(more or less ;-) + + The OpenBoopsi tree is structured in this way: + + OpenBoopsi root/ + Makefile + config.mk + + images/ + Makefile + class1/ + Makefile + config.mk + Class1.c + Class1Demo.c + class2/ + etc. + gadgets/ + Makefile + class1/ + Makefile + config.mk + etc. + include/ + common/ + general.mk + BoopsiStubs.h + etc. + images/ + Class1.h + etc. + etc. + + +These are things you should know: + +Makefiles +========= + +1) There is a global "config.mk" files where are defined all the compiler + specific variables, like command line options, tools, paths, etc. It is + divided in two sections and you usually should need to modify only the + first one. This file is placed in the OpenBoosi root. Run 'make help' for + a listing of the current configuration. + +2) There are different local "config.mk" files. They contain classes + specific informations, i.e. class name, class version, etc. They are + placed in every classes' directory and are required, so if you add a + new class to the OpenBoopsi project you must write one of this file. + An empty config.mk file is provided in the docs/ drawer with all the + explanations you will need. + +3) The top level Makefile will call all the makefiles in the other + subdirectories to build the complete distribution, as usual. However, + this Makefile also has a special target which sets up your build + environment. Without this preliminar step you won't be able to compile + anything. Read the INSTALL file or just run 'make help-setup' for a + more detailed explanation of this required step. + +4) The makefiles present in every classes' directory are simple dummy + makefiles. They just include the local "config.mk" file and the real + Makefile, so you just need to copy it in your class' directory without + any modifications. + +5) It is possibleto customize the local makefiles to pass custom "arguments" + to the true Makefile, so if e.g. your class need to link a specific object + you don't need to modify the general Makefile. Read the docs/empty_Makefile + file for a detailed explanation. + +6) You can obviously add to the local Makefile your own targets, e.g. for + creating a custom object that need to be linked to the demo program + (and that you will need to pass to the general Makefile via the argument + system described above). + +7) The "general.mk" file in the common/ directory is the Makefile used to + compile all the classes. It is included by the various local makefiles. + This method has three great advantages: 1) if the Makefile is changed or + improved it does not need to be copied in every subdirectories and 2) + you don't need to write your own custom Makefile, just the config.mk + 3) if you write a better/different Makefile other user can take + advantages of this just by including your Makefile instead of the + standard one. + +8) Remember that custom makefiles must support the defined targets or it + will be impossible to build all the distribution calling the top level + Makefile. You can find a list of the required targets and their purposes + in the general.mk file. + +9) If you want your own custom Makefile we suggest you to put it in the + common/ directory (so don't call it Makefile, give it a different name) + and then change your class' local Makefile to include your custom true + Makefile instead of the default one. In this way other people can use your + Makefile without the need to copy it to their subdirectories. + + +Includes +======== + +1) All the includes must be placed in the appropriate include/ subdirectories. + You must leave includes in the classes subdirectories only if they e.g. contain + private definitions needed by the class only, i.e. no other programs or classes + can include it. + +2) The makefiles already know where they should search for the needed + includes and how to tell the compiler to find them, so you should not + worry about this. + +3) To include the required headers in your programs or classes just follow + this example: + +#include "common/BoopsiStubs.h" +#include "images/VectorGlyph.h" +#include "gadgets/ListView.h" +#include "RequesterClass.h" +#include "MyPrivateInclude.h" + +4) IMPORTANT: in the example above the last two includes look identical, + however the first should be placed in the include/ dir (and not + in one of its subdirectories!) while the latter should go in the class + own directory. diff --git a/INSTALL b/INSTALL new file mode 100644 index 0000000..583664b --- /dev/null +++ b/INSTALL @@ -0,0 +1,15 @@ +$Id: INSTALL,v 1.1 2000/01/12 20:36:51 bernie Exp $ + +How to build the project +======================== + + Run "make setup".

It is + numbered 2 because it goes with version 2 of the ordinary GPL.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Library General Public License, applies to some +specially designated Free Software Foundation software, and to any +other libraries whose authors decide to use it. You can use it for +your libraries, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if +you distribute copies of the library, or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link a program with the library, you must provide +complete object files to the recipients so that they can relink them +with the library, after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + Our method of protecting your rights has two steps: (1) copyright +the library, and (2) offer you this license which gives you legal +permission to copy, distribute and/or modify the library. + + Also, for each distributor's protection, we want to make certain +that everyone understands that there is no warranty for this free +library. If the library is modified by someone else and passed on, we +want its recipients to know that what they have is not the original +version, so that any problems introduced by others will not reflect on +the original authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that companies distributing free +software will individually obtain patent licenses, thus in effect +transforming the program into proprietary software. To prevent this, +we have made it clear that any patent must be licensed for everyone's +free use or not licensed at all. + + Most GNU software, including some libraries, is covered by the ordinary +GNU General Public License, which was designed for utility programs. This +license, the GNU Library General Public License, applies to certain +designated libraries. This license is quite different from the ordinary +one; be sure to read it in full, and don't assume that anything in it is +the same as in the ordinary license. + + The reason we have a separate public license for some libraries is that +they blur the distinction we usually make between modifying or adding to a +program and simply using it. Linking a program with a library, without +changing the library, is in some sense simply using the library, and is +analogous to running a utility program or application program. However, in +a textual and legal sense, the linked executable is a combined work, a +derivative of the original library, and the ordinary General Public License +treats it as such. + + Because of this blurred distinction, using the ordinary General +Public License for libraries did not effectively promote software +sharing, because most developers did not use the libraries. We +concluded that weaker conditions might promote sharing better. + + However, unrestricted linking of non-free programs would deprive the +users of those programs of all benefit from the free status of the +libraries themselves. This Library General Public License is intended to +permit developers of non-free programs to use free libraries, while +preserving your freedom as a user of such programs to change the free +libraries that are incorporated in them. (We have not seen how to achieve +this as regards changes in header files, but we have achieved it as regards +changes in the actual functions of the Library.) The hope is that this +will lead to faster development of free libraries. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, while the latter only +works together with the library. + + Note that it is possible for a library to be covered by the ordinary +General Public License rather than by this special one. + + GNU LIBRARY GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library which +contains a notice placed by the copyright holder or other authorized +party saying it may be distributed under the terms of this Library +General Public License (also called "this License"). Each licensee is +addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also compile or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + c) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + d) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the source code distributed need not include anything that is normally +distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Library General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS + + Appendix: How to Apply These Terms to Your New Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). + + To apply these terms, attach the following notices to the library.

This facility is available in AmigaOS since Kickstart V36. +boopsi is primary meant as an OOP framework for GUI components such as +gadgets, images, texts and so on. + + The system provides several boopsi classes which are the OOP counterparts +of the plain Intuition gadgets and other important structures such as Image +and IntuiText. There are also classes that allow building a network of +interconnected boopsi objects so that each object can notify the others +about its attributes. This boopsi communication system enables the gadgets +to talk each other so they can react to user input in complex ways, freeing +the application from most of the GUI administration duties. + + +Other GUI systems +================= + + Unfortunately, the built-in Intuition classes are not very powerful, +nor flexible enough for todays applications. That's why so many +alternative GUI systems have appeared during the past years. Some +of these systems are also based on boopsi, while others provide +their own API through a shared library. + + The main disadvantage with these GUI systems mentioned above is +none of them is free. In this case we are referring to the GNU meaning +of the word `free'. It means that the users and the developers are +not given enough freedom. Some GUI systems are shareware, some others +come with a license that forbids or limits their use for commercial +applications. Few of them come with their source code and in most +cases they don't give you the freedom to change it. On the technical +side, the major limit of the current GUI systems is that they are +usually mutually exclusive. You can't mix objects from two different +systems to take advantage of the features of both. + + +About the boopsi OSS project +============================ + + The goal of this project is providing a comprehensive set of +boopsi classes for general application developement. The main +developemnt guidelines are: + + - providing a pure boopsi API for GUI construction. There + are no additional libraries. + + - integration with the system built-in classes, whenever + possible. + + - support the current V39/V40 OS along with the current + RTG systems. + + - Sticking to clean AmigaOS programming, except when it is + absolutely impossible to do so to workaround known + OS bugs. + + - Adopting a distributed developement model. Source code + is freely available and anyone is allowed to improve or + add new functionality. + + - Leave the choice to the application developer. + The classes will be available in several flavours, + including shared class libraries, linker library and + a monolithic shared library. + + - Find the best trade-off beteen efficiency, portability + and configurability + + +DISCLAIMER +========== + + This software is provided AS-IS, without any explicit or implied warranty. + + This software is to be considered PRELIMINARY and SUBJECT TO CHANGE. +It has not been tested accurately and it may contain BUGS that could +easily CRASH YOUR SYSTEM. diff --git a/STYLE b/STYLE new file mode 100644 index 0000000..4f153d4 --- /dev/null +++ b/STYLE @@ -0,0 +1,185 @@ +$VER OpenBOOPSI Project Style Guide 1.1 (4.5.99) + + + OpenBOOPSI Project Style Guide + +---- + + +0. SUMMARY + + 1. Introduction + 2. Comments + 2.1 General Rules + 2.2 Language + 2.3 Single line comments + 2.4 Multi line comments + 3. Blank Spaces + 3.1 Tabs + 3.2 Spaces + 3.3 Empty lines + 4. Naming Conventions + 4.1 General Rules + 4.2 Functions + 4.3 Variables + + +1. INTRODUCTION + + This is a brief guide on recommended source code formatting style + for the OpenBOOPSI Project classes. Every source file added to this + project should conform as close as possible to the rules given in + this document to mantain consistency within the source tree. + + It might happen that you're already used to a different coding + style. Yes, we all understand well that changing your style can be + frustrating for any programmer. But the need to keep the source + code style consistent is more important than each one's habits. + No one will blame you if you don't strictly follow these + guidelines, but we will be glad if you do. + + +2. COMMENTS + + 2.1 GENERAL RULES + + Comment as much as you can. Other programmers will read your + sources and since most of them will have different knowledge of + Amiga programming and/or different ways to do a certain thing they + may not understand the purpose or the inner working of some of your + code, so try to explain what you are doing. Obviously avoid comments + such as "now open a window" right above a OpenWindow() function call. + + 2.2 LANGUAGE + + Comments must be written in english. + + 2.3 SINGLE LINE COMMENTS + + Single line comments should follow the ANSI C syntax, i.e. + using the "/* */" construct. C++ comments must not be used + because not all C compilers do support them. + + 2.4 MULTI LINE COMMENTS + + Comments spanning over multiple lines should be formatted this way: + + /* This is a very very very + * very very long comment! + */ + + +3. BLANK SPACES + + 3.1 TABS + + Tabs are four spaces wide. + + 3.2 SPACES + + There should be a space after commas. + + There should never be a space after a * when it's used with pointers, + e.g.: + + ULONG *pointer = NULL; + *pointer = 45 * y; + + There should be a blank space around operators, e.g.: + + var1 + var2; + var1 & var2; + etc. + + the only exceptions are prefix and postfix ++ and -- operators, + i.e.: + + var--; + ++var; + + Before a parenthesis there should never be blank spaces if + it follow a keyword or a function name. e.g. + + if() /* good */ + DoMethod(); /* also good */ + while () /* wrong! */ + yourfunction (); /* also wrong! */ + + 3.3 EMPTY LINES + + After the #include block and after the #define one there should be + two empty lines. + + Between the declaration of the global variables and the beginning of + the code there should be two empty lines. + + Between the end of a function and the next one there should be three + empty lines. + + Any code block enclosed in braces should be preceded by an empty line. + An open brace should be on a line by itself. After a closing brace there + should be one empty line, except when another closing brace follows. e.g. + + if(z == 1) + { + z++; + } + + y += z + 3; + + if(y > 8) + { + f = do_some_stuff(); + + if(f == TRUE) + { + printf("ok!\n"); + } + } + + /* the following is wrong! */ + + if(y==1) { + z++; + } + y+=z +3; + if (y >8) + { etc. } + + +4. NAMING CONVENTIONS + + 4.3 GENERAL RULES + + Everything related to the classes (methods, functions, etc.) should + have a prefix (two or three letter maximum) that recalls the name of + the class. i.e. if your class is called "BananaSplit" its methods + should be called something like BSM_SHAKE, its attributes should look + like BSA_SugarSpuns, etc. + + 4.2 FUNCTIONS + + Method functions should obviously follow the general rule and have + the above mentioned prefix, e.g.: + + BS_GoActive(); + + Function names should have the first letters of each word + forming their names capitalized, like system's one. e.g.: + + MyWonderfulFunction() + + 4.3 VARIABLES + + Variables name must be in english and must have a meaning! Please + avoid names such as "foobar" or "dummy"! We hate them! + Some examples: + + struct Window *win; /* these are good */ + ULONG result; + + struct BitMap *dummy1; /* these are wrong! */ + struct RastPort *dummy2; + + Names of local variables should be all in lowercase. Global + variables should have their initials uppercase. diff --git a/TODO b/TODO new file mode 100755 index 0000000..e69de29 diff --git a/classes/ExtRequesterClass/Makefile b/classes/ExtRequesterClass/Makefile new file mode 100644 index 0000000..92449a0 --- /dev/null +++ b/classes/ExtRequesterClass/Makefile @@ -0,0 +1,23 @@ +# +# $Id: Makefile,v 1.1 2000/01/12 20:40:56 bernie Exp $ +# +# Copyright (C) 1999 by Matteo Cavalleri +# + +include $(TOP)/config.mk + +ARG_COMMON := +ARG_ALL := $(ARG_COMMON) +ARG_LIB := $(ARG_COMMON) +ARG_DEBUG := $(ARG_COMMON) +ARG_PRIVATE := $(ARG_COMMON) +ARG_OBJ := $(ARG_COMMON) + +DEP_COMMON := +DEP_ALL := $(DEP_COMMON) +DEP_LIB := $(DEP_COMMON) +DEP_DEBUG := $(DEP_COMMON) +DEP_PRIVATE := $(DEP_COMMON) +DEP_OBJ := $(DEP_COMMON) + +include $(TOP)/common/general.mk diff --git a/classes/Makefile b/classes/Makefile new file mode 100644 index 0000000..54b2e11 --- /dev/null +++ b/classes/Makefile @@ -0,0 +1,9 @@ +# +# $Id: Makefile,v 1.1 2000/01/12 20:40:06 bernie Exp $ +# +# Copyright (C) 1999 by Matteo Cavalleri +# + +SUBDIRS := ExtRequesterClass + +include $(TOP)/common/general.mk diff --git a/common/ClassLib.s b/common/ClassLib.s new file mode 100755 index 0000000..d9bc8c2 --- /dev/null +++ b/common/ClassLib.s @@ -0,0 +1,298 @@ +****************************************************************************** +* +* $VER: ClassLib.asm (5.9.97) +* +* Copyright (C) 1995,96,97 by Bernardo Innocenti +* +****************************************************************************** +* +* This source is based on the RomTag.asm source I've found somewhere :-) +* +* + INCLUDE "exec/types.i" + INCLUDE "exec/macros.i" + INCLUDE "exec/libraries.i" + INCLUDE "exec/lists.i" + INCLUDE "exec/alerts.i" + INCLUDE "exec/initializers.i" + INCLUDE "exec/resident.i" + INCLUDE "exec/execbase.i" + INCLUDE "libraries/dos.i" + + INCLUDE "exec/funcdef.i" + INCLUDE "exec/exec_lib.i" + + +; BOOPSI class libraries should use this structure as the base for their +; library data.

In uscita l'handler restituisce +la lista modificata, la quale diventerà l'ingresso per l'handler successivo. + +Il codice di un handler viene eseguito come una normale chiamata a funzione: +di conseguenza esso gira sempre nel contesto del task dell'input.device. + +Normalmente l'handler con priorità massima è quello della commodities.library +(che quindi intercetta gli eventi prima di chiunque altro), tranne che nel +caso in cui essa non sia stata ancora aperta. + +L'handler immediatamente successivo è tipicamente quello di Intuition; la +sua funzione è "interpretare", ed eventualmente filtrare, tutti quegli eventi +che possono influire sullo stato della GUI o sulle attività dei programmi che +ne fanno uso. + +Questo handler fondamentalmente si limita a chiamare la funzione Intuition() +della intuition.library, passandole come unico argomento il puntatore alla +lista di eventi ricevuto in ingresso. + +Intuition() verifica la natura di ogni singolo evento e, se necessario, +reagisce ad esso eseguendo opportune azioni, come ad esempio attivare una +finestra, modificare l'aspetto e lo stato di un gadget o inviare un messaggio +ad un applicativo. + +La casistica più comune comprende: + +· Refresh automatico di una componente della GUI (bordo di una finestra, + gadget non BOOPSI, barra del titolo di uno schermo). + +· Visualizzazione di menu + +· Invocazione dell'opportuno metodo di un gadget BOOPSI + +· Nessuna azione visibile (es.: click all'interno di una finestra, ma non + su un gadget) + +A ciascuna di queste azioni può essere associato l'invio di un particolare +messaggio, rappresentato da una struttura IntuiMessage, all'applicativo +"proprietario" della finestra correntemente attiva (normalmente il task che +l'ha aperta). + +Gli IntuiMessage hanno spesso una corrispondenza stretta con gli InputEvent +da cui derivano. + +Al termine di queste azioni gli eventi che non possono essere utili agli +handler successivi vengono rimossi dalla lista, altri (generalmente utili +a console.device) vengono aggiunti, e la funzione Intuition() termina +restituendo all'handler il puntatore alla nuova lista. + +Infine l'handler di Intuition restituisce a sua volta il puntatore +all'input.device che può quindi passarlo all'handler successivo, solitamente +quello di console.device. + _ _ _ _ _ _ + | \ \ \ \ \ | + |Applicativo| + |_\_\_\_\_\_| + InputEvent stream /|\ + .····················. _ _ _|_ _ __ + : : | | + _ _ _ _ _ _ _ _ _ _ _: _ _ _ _ __ _ _ V _ _ __ _ |Messaggio ad| +| | | | | | |applicativo | +|keyboard.device|-. | |==>|Input handler (CX) | |__ _ _ _ _ _| +|_ _ _ _ _ _ _ _| \ | | |_ _ _ _ _ _ _ _ _ _| /\ + _ _ _ _ _ _ _ _ \ | | _ __ _ _ V _ _ __ _ _ ||_ _ _ _ +| | \ |input.device| | | | | +|gameport.device|----->| task |==>|Input handler (I) |==>|Intuition()| +|_ _ _ _ _ _ _ _| / | | |_ _ _ _ _ _ _ _ _ _| |_ _ _ _ _ _| + _ _ _ _ _ _ _ _ / | | _ __ _ _ V _ _ __ _ || +| | / | | | | _ _ \/_ _ +| timer.device |-' | |==>|Input handler (c.d)| | | +|_ _ _ _ _ _ _ _| |__ _ _ _ _ _| |_ _ _ _ _ _ _ _ _ _| |Refresh | + : |della GUI| + _: |_ _ _ _ _| + / \_/ || + : _ _ _ _ \/_ _ _ _ + : | | + V |Esecuzione metodo| + ///// |_ _ _ _ _ _ _ _ _| + +Questo meccanismo comporta che l'unico codice eseguito nel contesto di un +applicativo che faccia uso di Intuition è quello che si occupa di rispondere +agli IntuiMessage ed intraprendere eventuali azioni in base al loro contenuto +(generalmente finalizzate a svolgere il compito richiesto dall'utente più +che a gestire l'interfaccia; tuttavia nel caso di GadTools alcune operazioni +di gestione della GUI vengono affidate al task dell'applicativo mediante le +funzioni GT_GetIMsg() e GT_ReplyIMsg()). + +In particolare, nel caso dei gadget BOOPSI, la risposta della GUI risulta +sempre immediata e "in tempo reale", indipendentemente dalle operazioni che +l'applicativo sta svolgendo nello stesso momento, poiché di fatto se ne +occupa asincronamente un altro task (quello dell'input.device). + + +Come si comporta MUI +-------------------- + +La differenza fondamentale tra MUI ed Intuition è che i suoi gadget, pur +essendo oggetti BOOPSI, sono sottoclassi di "rootclass" piuttosto che di +"gadgetclass".

Tutto ciò che quest'ultima rileva quando l'utente interagisce +con i gadget MUI è una serie di eventi IDCMP_MOUSEBUTTONS e IDCMP_MOUSEMOVE +che essa trasmette, invariati, al task proprietario della finestra. + +Quest'ultimo tipicamente si trova in uno stato di attesa degli eventi. +Per ogni evento ricevuto chiama una funzione MUI di gestione dell'input +(per l'esattezza invoca un metodo di una particolare classe) la quale +è poi in grado di determinare a quale gadget MUI va passato, mediante +l'invocazione di un suo opportuno metodo, l'evento appena letto. + _ _ _ _ _ _ _ _ _ __ + | \ \ \ \ \ \ \ \ \ \| + |Operazioni programma| + |_\_\_\_\_\_\_\_\_\_\| + _ _ _ _ _ _ _ _ __ /\ + _ _ _ _ _ _ | | _ _ _ _ _ _ _ _ _ _|| _ _ _ _ +| | |Semplice messaggio| | \ \ \ \ \ | | \ \ \ \ \ \ \ \ | +|Intuition()|==>| all'applicativo |---->|Applicativo| |Refresh della GUI| +|_ _ _ _ _ _| | (IDCMP_MOUSE#?) | |_\_\_\_\_\_| |_\_\_\_\_\_\_\_\_| + |__ _ _ _ _ _ _ _ _| || /\ + _ _ _ \/_ _ __ _ _ _ _|| _ _ _ _ + | \ \ \ \ \ \ \| | \ \ \ \ \ \ \ \ | + |Gestione input|==>|Esecuzione metodo| + |_\_\_\_\_\_\_\| |_\_\_\_\_\_\_\_\_| + +Con MUI, di conseguenza, la risposta della GUI (almeno con le classi di +gadget standard fornite con il pacchetto) risulta sincrona alle operazioni +del task dell'applicativo, in quanto avviene nel suo stesso contesto. + + +PROBLEMI + +Problema n. 1 (input.device bloccato; Intuition) +------------------------------------------------ + +La gestione dell'input secondo il modello di Intuition, cioè tramite un +handler, ha il vantaggio di garantire pressoché sempre una risposta immediata +da parte della GUI, anche nel caso in cui l'applicativo non fosse pronto a +reagire all'input ricevuto. + +Tuttavia, poiché l'handler di Intuition opera sempre, come già illustrato, +nel contesto dell'input.device, qualsiasi trasmissione di eventi di input +nel sistema risulta completamente bloccata fino alla conclusione delle sue +operazioni. + +Il problema si manifesta in modo evidente soprattutto con i gadget BOOPSI; +infatti l'handler invoca opportuni metodi di tali gadget quando l'input +dell'utente è diretto a loro o comporta una modifica del loro stato. Nel +caso di metodi particolarmente complessi, come quelli dei gadget associati +ai DataType, il tempo di esecuzione può essere elevato, e di conseguenza +la trasmissione dell'input nell'intero sistema può subire una sospensione di +durata non trascurabile. + +Il sintomo più tipico è il blocco del puntatore del mouse, ma anche altre +attività del sistema operativo che si basino su una regolare ricezione di +eventi di input (ad esempio quelli generati dal timer.device) rischiano di +venire ostacolate con conseguenze imprevedibili. + + +Problema n. 2 (refresh della GUI bloccato; MUI) +----------------------------------------------- + +Il sistema MUI presenta un problema per certi versi opposto, ma ugualmente +fastidioso per l'utente. Con i gadget di MUI le operazioni svolte nel +contesto del task dell'input.device sono sempre molto limitate e di breve +durata; si tratta per lo più di comunicare una serie di click dei pulsanti +del mouse (e spostamenti di quest'ultimo) all'applicativo associato al canale +IDCMP della finestra attiva. + +Ogni operazione relativa alla GUI viene poi effettuata nel contesto del task +che riceve i messaggi in questione. Nel caso esso sia occupato in qualche +elaborazione e quindi non si trovi in attesa di segnali dalla porta IDCMP, +come è facile immaginare, nessun tipo di aggiornamento della GUI verrà +attuato fino alla conclusione delle operazioni. + +L'utente, in questo caso, non osservando alcuna risposta dai gadget con cui +tenta di interagire, può avere l'impressione che l'intero programma sia +bloccato e non semplicemente impegnato in altre attività. + +Nel caso migliore l'utente si fa una cattiva opinione del programma; inoltre +l'incertezza sul da farsi può portare l'utente a danneggiare inavvertitamente +il lavoro che sta svolgendo mediante l'applicativo. Ad esempio, un tentativo +di selezione ripetuta dello stesso gadget (nella speranza di una ripresa del +funzionamento del programma) può provocare effetti collaterali indesiderati +nell'istante in cui l'applicativo ricomincia a gestire l'input e si occupa di +quello nel frattempo ricevuto. + + +IPOTESI DI SOLUZIONI + +Possibile soluzione per il problema n. 1 (sotto-task IDCMP in parallelo) +------------------------------------------------------------------------ + +Una possibile soluzione al primo problema, attuabile al livello di Intuition, +è la gestione multithreaded degli eventi di input trasmessi al suo handler +dall'input.device, che in tal modo si libererebbe molto rapidamente dopo +la chiamata alla funzione Intuition(). Come realizzare questo nella pratica? + +Un'idea potrebbe essere associare ad ogni schermo e finestra un task +dedicato, creato all'apertura ed eliminato alla chiusura. Ciascuno di questi +task riceverebbe solo gli eventi che lo riguardano e potrebbe gestirli del +tutto asincronamente al resto del sistema e in particolare all'input.device. + +Per rendere possibile ciò sarebbe necessario apportare alcune modifiche alla +funzione Intuition(): + +1. Essa dovrebbe, preliminarmente, esaminare la lista di InputEvent ricevuta + dall'input.device e in base ad essa costruire una seconda lista privata + copiando tutti gli eventi che riguardano la GUI. + +2. Fatto ciò, tutti gli eventi che non devono essere rilevati dagli altri + handler dovrebbero essere rimossi dalla lista principale. + +3. La lista privata di eventi dovrebbe poi essere separata in sottoliste, + ognuna indirizzata all'opportuna finestra (o all'opportuno schermo). + +4. Ogni sottolista dovrebbe essere spedita, tramite un opportuno messaggio, + al task associato alla finestra (o schermo) destinazione. + +5. A questo punto Intuition() potrebbe terminare subito la sua esecuzione, + senza aspettare alcuna risposta dai task a cui ha spedito i messaggi; + in questo modo l'input.device sarebbe subito libero di proseguire la + sua attività. + +Una possibile variante è il passaggio (subito dopo il punto 2) della lista +privata ad un task "intermedio" che si occupi di eseguire le operazioni +rimanenti; in questo caso Intuition() potrebbe terminare prima del punto 3. +Questo ipotetico task intermedio potrebbe ad esempio venire creato in modo +automatico all'apertura della intuition.library. + +Occorre prestare molta attenzione all'implementazione del punto 2, in quanto +è necessario stabilire delle regole precise in base alle quali si possa +determinare IN ANTICIPO e senza ambiguità se un evento riguarda o no la GUI e +se esso debba venire trasmesso o no ai successivi handler. Questo potrebbe, +oggettivamente, non essere un compito facile. + +In particolare, se un evento deve essere modificato da Intuition e poi +trasmesso al resto degli handler, bisogna che: + +- Si sappia già come modificarlo PRIMA di passarlo al task destinatario, + per non dover aspettare che questo termini fornendo informazioni sulla + modifica da effettuare (soluzione non sempre applicabile), oppure + +- Il task destinatario, dopo avere modificato personalmente l'evento, si + occupi di REINSERIRLO nella catena di InputEvent a monte dell'handler di + Intuition. Questo si può realizzare ad esempio aggiungendolo ad una coda + di eventi globale periodicamente letta dall'handler, oppure sfruttando + la commodities.library. Non basta chiamare direttamente Intuition() con + l'evento in questione poiché si rimarrebbe nel contesto del task. + Le regole per realizzare ciò potrebbero risultare abbastanza complicate. + +Ammettendo di risolvere questi problemi, restano da esaminare i compiti dei +singoli task destinatari. + +Quelli associati alle finestre svolgerebbero esattamente gli stessi compiti +che attualmente sono svolti dalla funzione Intuition(), cioè aggiornare lo +stato della GUI, invocare opportuni metodi di eventuali gadget BOOPSI +selezionati e spedire IntuiMessage all'applicativo che "possiede" la finestra +(con l'unica avvertenza, ovvia del resto, di assicurarsi che il task sia +completamente rientrante ed esegua una corretta arbitrazione sui dati globali +di IntuitionBase). + +I task associati agli schermi non dovrebbero fare altro che gestire la +selezione degli unici due possibili gadget, quello di trascinamento e quello +di profondità, nonché la disattivazione di tutte le finestre in caso di +click del mouse su una zona libera dello schermo, l'autoscrolling e lo screen +dragging tramite Amiga sinistro + mouse. + +Si potrebbe anche pensare ad un ulteriore task indipendente che gestisca +semplicemente il movimento del puntatore, ma questo è un compito talmente +banale che potrebbe essere svolto direttamente (e più rapidamente) dalla +funzione Intuition(). + _ _ _ _ _ _ + | \ \ \ \ \ | + |Applicativo| + |_\_\_\_\_\_| + InputEvent stream /|\ + .····················. | + : : :::::::::::::::: + _ _ _: _ _ _ _ __ _ _ V _ _ __ _ ::Messaggio ad:: +| | | | ::applicativo::: +| |==>|Input handler (CX) | :::::::::::::::: +| | |_ _ _ _ _ _ _ _ _ _| /\ +| | _ __ _ _ V _ _ __ _ _ _ _ _ _ _ || +|input.device| | | | | ::::::::::::::::: +| task |==>|Input handler (I) |==>|Intuition()|-->::Task finestra:: +| | |_ _ _ _ _ _ _ _ _ _| |_ _ _ _ _ _| ::::::::::::::::: +| | _ __ _ _ V _ _ __ _ || +| | | | \/ +| |==>|Input handler (c.d)| ::::::::::::: +|__ _ _ _ _ _| |_ _ _ _ _ _ _ _ _ _| ::Refresh:::: + : ::della GUI:: + _: ::::::::::::: + / \_/ || + : \/ + : ::::::::::::::::::::: + V ::Esecuzione metodo:: + ///// ::::::::::::::::::::: + + +Per concludere, si può osservare che in realtà sarebbe abbastanza raro che +la stessa lista contenga eventi indirizzati a finestre diverse; l'utente, +in circostanze normali, non dovrebbe essere più veloce dell'elaborazione +dell'input da parte del sistema.

Tale task potrebbe essere creato +dal metodo OM_NEW della classe e distrutto in seguito da OM_DISPOSE. +Eventuali valori di ritorno diretti all'applicativo potrebbero essere +comunicati mediante messaggi (gestiti automaticamente dal task del gadget). + +Il refresh grafico dei gadget, invece, essendo generalmente un'operazione +abbastanza rapida, potrebbe essere affidato ad un unico task globale; una +possibilità sarebbe quella di creare questo task all'apertura della libreria +MUIMaster. + + :::::::::::::::::::::::: ::::::::::::::::::: + ::Operazioni programma::<==::Task del gadget:: + :::::::::::::::::::::::: ::::::::::::::::::: + _ _ _ _ _ _ _ _ __ /|\ + _ _ _ _ _ _ | | _ _ _ _ _ __ _ _ _ _ | _ _ _ _ +| | |Semplice messaggio| | \ \ \ \ \ \ \| | \ \ \ \ \ \ \ \ | +|Intuition()|==>| all'applicativo |-+ |Gestione input|==>|Esecuzione metodo| +|_ _ _ _ _ _| | (IDCMP_MOUSE#?) | | |_\_\_\_\_\_\_\| |_\_\_\_\_\_\_\_\_| + |__ _ _ _ _ _ _ _ _| | /\ | + | _ _ ||_ _ _ \|/ + | | \ \ \ \ \ | ;;;;;;;;;;;;;;;;;;;;; + +-->|Applicativo| ;;Refresh della GUI;; + |_\_\_\_\_\_| ;;;;;;;;;;;;;;;;;;;;; + +Se le operazioni di refresh non necessitano di restituire alcun valore al +dispatcher dell'oggetto (oppure alla funzione di MUI che gestisce l'input) +quest'ultimo verrebbe disimpegnato immediatamente; in caso contrario sarebbe +sufficiente che il task preposto al refresh svolgesse tutte le sue operazioni +prima di rispondere al dispatcher con ReplyMsg(), e copiasse il valore di +ritorno in un apposito campo del messaggio "restituito" al mittente. + +Questo ovviamente terrebbe impegnato il task dell'applicativo per un tempo +leggermente superiore, ma le operazioni di refresh grafico puro e semplice +non dovrebbero, nella maggior parte dei casi, richiedere più di qualche +millisecondo (come del resto accade per Intuition nel caso di gadget non +troppo complicati). Chiaramente se tale comportamento fosse richiesto per +TUTTI i gadget sarebbe più conveniente evitare del tutto l'uso di un task +separato per il refresh, mantenendo però quello dedicato al callback. + +Sarebbero possibili diverse variazioni sul tema: ad esempio, l'ordine in cui +vengono "richiamati" i due task potrebbe influenzare, sia pure di poco, la +prontezza del refresh e quindi della risposta all'utente da parte della GUI; +oppure in certi casi potrebbe essere conveniente creare "al volo" il task +preposto al callback in modo che l'applicativo possa eseguire più volte +contemporaneamente la stessa funzione (se la sua natura lo consente). + +In ogni caso questa soluzione eliminerebbe alla radice il problema del +"blocco" apparente della risposta della GUI durante un'intensa attività +dell'applicativo, senza per questo tornare al modello "mono-threaded" +adottato attualmente da Intuition. L'alternativa proposta per quest'ultimo +(vedi paragrafo precedente) risolverebbe in teoria anche il problema di MUI, +ma solo se i gadget MUI fossero istanze di "gadgetclass", cosa che al +momento, in pratica, non accade. + + +CONSIDERAZIONI FINALI + +Funzionamento seriale dell'input.device +--------------------------------------- + +Come già detto, l'input.device propaga lo stream di eventi di input +attraverso i vari handler in cascata. Gli handler non sono altro che +funzioni chiamate, una dopo l'altra, dal task dell'input.device; ogni +handler riceve in ingresso il valore di uscita del precedente (e cioè +il puntatore ad una particolare lista di InputEvent). + +Questo è un meccanismo intrinsecamente seriale; inoltre esso implica che gli +handler di priorità più alta (come quello di Intuition) debbano esaminare, +tra gli altri, molti eventi che non li riguardano direttamente e che vanno +semplicemente trasmessi agli handler successivi. + +Come aumentare il parallelismo nelle operazioni dell'input.device? + +Ingenuamente si potrebbe pensare di avere diverse code, ognuna gestita da +un task indipendente, tra cui suddividere gli eventi in base al tipo degli +handler che tali code alimentano; ovviamente occorrerebbe che gli handler +di una coda non abbiano mai la necessità di trasmettere eventi a quelli di +un'altra coda. + +Purtroppo in pratica questo non è una soluzione, dato che porterebbe a +ricreare la situazione corrente. Infatti normalmente gli handler esistenti +nel sistema sono pochi (per lo più Commodities, Intuition e console.device) +ed è difficile individuare tipi di eventi che non interessino, anche solo +potenzialmente, almeno due di essi. + +In particolare, la quasi totalità degli eventi di input generati dall'utente +interessa in qualche modo Intuition, che viene ad essere un vero e proprio +"collo di bottiglia". + +Più vantaggioso risulterebbe applicare questa soluzione al livello dei +singoli handler; ciascuno di essi, a meno che il suo funzionamento sia +molto semplice, potrebbe gestire l'input in arrivo ripartendolo in modo +opportuno tra diversi task paralleli (come illustrato riguardo al problema +di Intuition). + +In questo modo sorgerebbe però il problema della trasmissione del flusso +di input lungo la catena di handler. Ognuno di essi potrebbe trasmettere +al successivo solo gli eventi che può scartare immediatamente come "non +rilevanti" per le sue attività, ma gli sarebbe preclusa la possibilità di +modificare gli eventi utilizzati, o crearne di nuovi in base ai risultati +della loro elaborazione, e reinserirli nella posizione originale: questa +operazione generalmente richiederebbe la conoscenza di dati non disponibili +a priori e, d'altra parte, una sincronizzazione con i suoi task per ottenere +da essi tali dati annullerebbe ovviamente tutti i vantaggi del parallelismo. + +E` dunque necessario, volendo impiegare un simile modello: + +· Stabilire delle regole estremamente precise per decidere quando l'ordine + relativo di due eventi vada mantenuto oppure sia ininfluente; + +· Limitare al massimo la necessità di trasmettere informazioni tra un + handler e il successivo (nel caso di entità strettamente connesse, come + Intuition e console.device, questo potrebbe rivelarsi un problema serio); + +· Assicurarsi, ad esempio mediante semafori, che venga sempre mantenuta la + consistenza interna dei valori che definiscono lo stato di un handler (e + quindi dell'entità software che si appoggia ad esso) anche in presenza + di numerosi sotto-task che possono accedere a tali valori. + +Ad esempio, se l'utente attiva una finestra di Shell e poi preme un tasto +sulla tastiera, è necessario che il console.device riceva l'evento "finestra +attiva" PRIMA di quello "tasto premuto", nonostante il fatto che il secondo +potrebbe venire trasmesso immediatamente mentre il primo richiederebbe una +più lunga elaborazione da parte di Intuition. + +Ancora, quando l'utente trascina un gadget proporzionale sarebbe auspicabile +che la posizione relativa di knob e puntatore del mouse rimanesse costante, +anche se gli spostamenti dei due oggetti vengono gestiti da due diversi task. + +La trasmissione di eventi agli handler successivi potrebbe ad esempio essere +implementata mediante una coda ausiliaria globale svuotata periodicamente, +accessibile a tutti i sotto-task di un handler, purché si presti la massima +attenzione a mantenerla sempre perfettamente ordinata e ad inserire in essa +anche quegli eventi (e solo quelli) che, pur non dovendo essere elaborati +dall'handler corrente, possono risentire dell'ordine in cui vengono trasmessi +rispetto a certi altri eventi. + +Queste considerazioni non pretendono certamente di costituire una soluzione +completa, preferibile ad altre o facilmente realizzabile; si tratta solo di +riflessioni su alcuni aspetti del problema di cui probabilmente converrebbe +tenere conto. + + +Fattibilità di un patch per Intuition +------------------------------------- + +E` possibile, tramite un patch, applicare all'attuale versione di Intuition +i criteri appena esposti? + +Probabilmente no. + +L'idea sarebbe di applicare un patch alla funzione Intuition() per forzare +il passaggio dell'input ad un task separato che se ne occupi, permettendo +all'handler di Intuition di terminare subito la sua esecuzione. Ma anche +immaginando di risolvere quasi tutti i problemi prima descritti, resta sempre +l'impossibilità di garantire la consistenza dei dati PRIVATI contenuti nella +struttura IntuitionBase, a cui sarebbe facile, in questo modo, effettuare +un accesso asincrono. + +Non è escluso che si possa trovare una soluzione anche a questo problema, ma +con ogni probabilità a questo punto conviene aspettare che sia Amiga Inc. ad +implementare nel sistema operativo una gestione dell'input più efficiente. + diff --git a/docs/LabelTextIClass.doc b/docs/LabelTextIClass.doc new file mode 100755 index 0000000..669699c --- /dev/null +++ b/docs/LabelTextIClass.doc @@ -0,0 +1,181 @@ +TABLE OF CONTENTS + +labeltext.image/labeltext.image + labeltext.image/labeltext.image labeltext.image/labeltext.image + + NAME + labeltext.image -- label BBOPSI image (V1) + + FUNCTION + The labeltext class is a little BOOPSI class that provides a complete + label handling. A label can be placed inside or outside a gadget + (above, below, left, right or inside) with different alignments + (centered, left aligned, right aligned, etc.) with a couple of + different rendering methods (normal, hilighted, 3d). It is able to + use the standard DrawInfo pens when no custom pens are supplied and + the system default font when no custom font is supplied. + It supports various image states (i.e. normal, selected, disabled, + etc.) This class has also a nice API for easy layer clipping when it + is necessary. + + METHODS + IM_DRAW -- Tell the class to render itself. Before calling this + method for the first time you should first invoke the IM_FRAMEBOX + method and then the IM_DRAW one using the FrameBox Left and Top + field or the Image LeftEdge and TopEdge fields. Note that these + coordinates are NOT exactly the ones the label will use, i.e. + if you do a Text() call using that coordinates you'll get a text + slightly shifted. In other words if you calculate yourself the + coordinates of the label you won't be able to draw it in the right + place. This is required for an easy layer clipping support. + NB: You must alway supply the imp_Offset coordinates, even if the + Image->LeftEdge and Image->TopEdge field already contain the right + values. + + IM_FRAMEBOX -- This method tell the class to calculate its position + relative to the ContentsBox coordinates and according to its + alignment attributes. For this reason the ContenstBox is usually + filled with the gadgets coordinates.

If not the FrameBox Left and + Top fields will be set to -1. You can blindly pass this values + to the IM_DRAW or IM_ERASE method, since the class knows that it + has not to render itself. The FrameBox Width and Height fields + are set to an arbitrary value to avoid problems if the gadget do + layer clipping without checking the result of the IM_FRAMEBOX + method. + + NOTE: If you change some attributes (e.g. the font) you should call + the IM_FRAMEBOX method again, so that the label can recalculate + its position and size. + + TAGS + + ELA_Label -- Pointer to the string the class will print.

In effetti a quanto ho visto +finora ObtainGIRPort() restituisce sempre lo stesso indirizzo, qualunque sia +il contesto. + +I valori di gi_Screen, gi_Window e gi_Requester sono inizializzati in modo +opportuno (oppure nulli se non applicabili, a parte gi_Screen). + +Tabella di esempio per un gadget in una finestra non GZZ: + + +-------------------------------------------------------------------------+ + | gi_Window: W | + | gi_Layer: RL, LWindow: W, LRastPort: R | + | gi_RastPort: S, BitMap: bm, Layer: SL, LWindow: 0, LRastPort: S | + | gi_Window->RPort: R, BitMap: bm, Layer: RL, LWindow: W, LRastPort: R | + | gi_Window->BorderRP: 0, BitMap: --, Layer: --, LWindow: -, LRastPort: - | + | gpr_RPort: C, BitMap: bm, Layer: RL, LWindow: W, LRastPort: R | + | ObtainGIRPort(): C, BitMap: bm, Layer: RL, LWindow: W, LRastPort: R | + +-------------------------------------------------------------------------+ + +Tabella di esempio per un gadget non GZZ in una finestra GZZ: + + +-------------------------------------------------------------------------+ + | gi_Window: W | + | gi_Layer: RL, LWindow: W, LRastPort: R | + | gi_RastPort: S, BitMap: bm, Layer: SL, LWindow: 0, LRastPort: S | + | gi_Window->RPort: R, BitMap: bm, Layer: RL, LWindow: W, LRastPort: R | + | gi_Window->BorderRP: B, BitMap: bm, Layer: BL, LWindow: W, LRastPort: B | + | gpr_RPort: C, BitMap: bm, Layer: RL, LWindow: W, LRastPort: R | + | ObtainGIRPort(): C, BitMap: bm, Layer: RL, LWindow: W, LRastPort: R | + +-------------------------------------------------------------------------+ + +Tabella di esempio per un gadget GZZ in una finestra GZZ: + + +-------------------------------------------------------------------------+ + | gi_Window: W | + | gi_Layer: BL, LWindow: W, LRastPort: B | + | gi_RastPort: S, BitMap: bm, Layer: SL, LWindow: 0, LRastPort: S | + | gi_Window->RPort: R, BitMap: bm, Layer: RL, LWindow: W, LRastPort: R | + | gi_Window->BorderRP: B, BitMap: bm, Layer: BL, LWindow: W, LRastPort: B | + | gpr_RPort: C, BitMap: bm, Layer: BL, LWindow: W, LRastPort: B | + | ObtainGIRPort(): C, BitMap: bm, Layer: BL, LWindow: W, LRastPort: B | + +-------------------------------------------------------------------------+ + +Il campo gi_Domain contiene larghezza e altezza del "contenitore logico" del +gadget. Nel caso di un gadget SCRGADGET, l'altezza è stranamente quella dello +schermo, mentre sarebbe più corretto se fosse quella della titlebar. Inoltre +un gadget che appartenga ad un gruppo ha come "contenitore logico" quello che +contiene il gruppo, e non il gruppo stesso (probabilmente in quanto il gruppo +non ha un layer proprio). +Gli offset contenuti in gi_Domain sono la distanza della posizione (espressa +in coordinate di schermo) del layer associato al "contenitore logico" del +gadget dalla posizione (sempre in coordinate di schermo) del suo "contenitore +fisico primario" (cioè lo schermo per i gadget SCRGADGET e la finestra per +tutti gli altri, anche se REQGADGET oppure appartenenti ad un gruppo). + +La funzione DoGadgetMethodA() crea una struttura GadgetInfo appropriata +in base al tipo di gadget di cui viene invocato il metodo. Se è di tipo +GZZGADGET, REQGADGET o SCRGADGET viene scelto il layer corretto, e anche +gi_Domain viene inizializzato adeguatamente. + +Un problema è che "gadgetclass" e "icclass" nell'implementare il metodo +OM_NOTIFY non chiamano DoGadgetMethodA() per invocare il metodo OM_UPDATE +dell'oggetto ICA_TARGET, bensì gli passano direttamente il puntatore a +GadgetInfo ricevuto, che fa riferimento al contesto dell'oggetto notificante +e non, come sarebbe corretto, a quello dell'oggetto notificato! + +Non si devono annidare chiamate a ObtainGIRPort(), altrimenti la RastPort +clonata (sempre la stessa) può venire modificata ad ogni chiamata. In +realtà probabilmente se si rimane nello stesso contesto la RastPort clonata +viene reinizializzata ogni volta con gli stessi valori, per cui non cambia +niente. Il vero pericolo sta nell'invocare un metodo di un altro gadget che +chiami ObtainGIRPort() mentre si è ancora all'interno del proprio blocco +ObtainGIRPort(). +In entrambi i casi comunque può verificarsi un errore 01000008 (Semaphore +in illegal state). +Del resto chiamare tanto ObtainGIRPort() quanto DoGadgetMethodA() all'interno +di un blocco ObtainGIRPort() dovrebbe essere scorretto comunque (sono due +funzioni di Intuition). + + +Note varie +---------- + +GACT_IMMEDIATE viene sempre rispettato anche per i gadget custom o BOOPSI. +Il valore di Code del messaggio IDCMP_GADGETDOWN è sempre zero e non può +essere impostato dal dispatcher in alcun metodo (GM_HITTEST/GM_GOACTIVE). + +GACT_RELVERIFY è necessario affinché l'uso di GMR_VERIFY + gpi_Termination +generi effettivamente un messaggio IDCMP_GADGETUP; in sua assenza esso non +viene generato. Viceversa la sua presenza non garantisce l'invio di tali +messaggi; ciò è deciso dal dispatcher nei metodi GM_GOACTIVE e GM_HANDLEINPUT. + +La documentazione del metodo IM_FRAMEBOX sul RKM è sbagliata! Viene invertito +il ruolo di imp_ContentsBox e imp_FrameBox. + diff --git a/docs/empty_Makefile b/docs/empty_Makefile new file mode 100644 index 0000000..c17c250 --- /dev/null +++ b/docs/empty_Makefile @@ -0,0 +1,96 @@ +# +# $Id:$ +# +# Copyright (C) 1999 by Matteo Cavalleri +# + +## This is the 'local' makefile, i.e. the makefile +## that is placed in very classes' directory. +## You can simply copy it in your class' directory +## and rename it to 'Makefile', or, if you want, you +## can customize it. +## +## We also suggest you to delete the lines beginning +## with two '##' like the ones you are reading now. +## This will make the processing of this file faster +## since make won't have to strip tons of comments. +## +include $(BOOPSITOP)/config.mk +## +## This include the local configuration +## for your class, i.e. the file with +## the class name, version, etc. +## It must be present and properly +## customized.

Window was being positioned just below +** the screen title bar, but it was looking on the titlebar height of +** the screen being captured instead of the screen when the window was +** to be opened +** +** - Changed PATTA_#? attributes to PIPA_#? attributes in the boopsi +** interconnection diagram. PATTA_ is the attribute prefix for the +** pattedit.gadget, another boopsi class written by me +** +** - Changed to always keep a lock on the screen where the window opens. +** This is needed because we are trying to free the associated DrawInfo +** strucure *after* closing the window. Without a proper lock, our host +** screen could close just after we closed our window, which would make +** the parameter we pass to FreeScreenDrawInfo() an invalid pointer +** +** - Fixed a bug that caused a call to still BltBitMapRastPort() with a +** NULL BitMap pointer when the PIPA_BitMap attribute was set to NULL +** +** - Added error report for bad arguments +** +** +** 2.2 (28.4.97) +** +** - Added gcc compiler support (untested) +** +** - Now uses a custom DoMethod() stub (faster than calling amiga.lib one) +** +** - Fixed the arrow buttons positioning when their width/height is +** not the same of the size gadget +** +** 2.3 (10.5.97) +** +** - Fixed LEFT, TOP, WIDTH & HEIGHT command line arguments. The +** OpenPIPWin() function was passing the *pointers* to the LONG +** values to OpenWindowTags(). (Riccardo Torrini) +** +** - Dragging the view to the extreme left or top does no longer send +** negative numbers when notifying the sliders. +** +** - Removed test to check if GetScreenDrawInfo() fails because this +** function is always successful +** +** +** 2.4 (15.8.97) +** +** - Added StormC compiler support +** +** - gcc support tested: works fine with latest GeekGadgets snapshot +** +** +** 2.5 (15.9.97) +** +** - Compiled with SAS/C 6.58 +** +** - Improved SMakefile, now PIPWin is not need to be linked with +** any static libraries +** +** - Size reduced even more! +** +** 2.6 (13.10.97) +** +** - Fixed scroll bars positioning with non standard window +** border sizes +** +** - gcc version can now be built without linking with libnix +** +** - Replaced call to RefreshGList() with the new PIPM_Refresh +** class method, which in turn calls GM_RENDER with mode GREDRAW_UPDATE. +** +** +** To Do +** ===== +** +** - Add a requester to select a public screen to snoop +** +** - Allow opening more than one window +** +** - Workbench startup and ToolTypes parsing +** +** - Allow zooming into the bitmap +** +** - Make the pipclass update its imagery automatically at given +** time intervals. This would require creating a Process for each +** istance the class, or perhaps one single Process for all objects. +** Unfortunately, most gadgetclass methods can not be called by +** soft interrupts, so it seems we really need a process :-( +** +** - This one is very ambitious: it should be possible to forward mouse +** and keyboard input to the screen being displayed. This would allow +** the user to actually USE programs without bringing their screens +** to front +** +** - Optimize display scrolling in some special cases. When the bitmap +** of the screen being displayed is not the same format of the bitmap +** where the PIP gadget renders (i.e.: they arn't `friend bitmaps'), +** some kind of conversion (e.g.: planar to chunky) will be done +** transparently by CopyBitMapRastPort().
