Subject: SDL: video/quartz cleanup
while doing some experimental changes in the quartz code, I was annoyed
by having to recompile that one big .o file over and over again. So I
decided to finally realize one TODO: properly splitting the code over
multiple files :-).
With two exceptions, I didn't make code changes, only rearranged files
and added new headers. Since there are several new files, making a
patch didn't work out so well, so I decided to just send you all the
new & modified files.
The one source change I made is related to showing/hiding the mouse. I
renamed cursor_visible to cursor_should_be_visible and cursor_hidden to
cursor_visible; I think that makes reading the code easier.
Then I added two new functions: QZ_ShowMouse and QZ_HideMouse. They
help manage cursor_visible (the former 'cursor_hidden'). Finally I
replaced the Carbon ShowCursor/HiderCuror calls by [NSCursor hide] and
[NSCursor unhide]. The API docs are not conclusive, but it might be
that with those the "cursor_visible" (former 'cursor_hidden') hack may
not be necessary anymore; however so far I didn't test this hypothesis,
so I left that in.
The other change was to remove in_foreground and use [NSApp isActive]
instead: Manually keeping track of whether we are in the foreground is
error prone. This should work better in some corner cases.

============================================================================== Using the Simple DirectMedia Layer with Mac OS X ============================================================================== These instructions are for people using Apple's Mac OS X (pronounced "ten"). From the developer's point of view, OS X is a sort of hybrid Mac and Unix system, and you have the option of using either traditional command line tools or Apple's IDE ProjectBuilder (PB). To build using the command line, use the standard configure and make process: ./configure make make install (You may need to create the subdirs of /usr/local manually.) To use the library once it's built, you essential have two possibilities: use the traditional autoconf/automake/make method, or use Apple's Project Builder. ============================================================================== Using the Simple DirectMedia Layer with a traditional Makefile ============================================================================== An existing autoconf/automake build system for your SDL app has good chances to work almost unchanged on OS X. However, to produce a "real" MacOS X binary that you can distribute to users, you need to put the generated binary into a so called "bundle", which basically is a fancy folder with a name like "MyCoolGame.app". To get this build automatically, add something like the following rule to your Makefile.am: bundle_contents = APP_NAME.app/Contents APP_NAME_bundle: EXE_NAME mkdir -p $(bundle_contents)/MacOS mkdir -p $(bundle_contents)/Resources echo "APPL????" > $(bundle_contents)/PkgInfo $(INSTALL_PROGRAM) $< $(bundle_contents)/MacOS/ You should replace EXE_NAME with the name of the executable. APP_NAME is what will be visible to the user in the Finder. Usually it will be the same as EXE_NAME but capitalized. E.g. if EXE_NAME is "testgame" then APP_NAME usually is "TestGame". You might also want to use @PACKAGE@ to use the package name as specified in your configure.in file. If your project builds more than one application, you will have to do a bit more. For each of your target applications, you need a seperate rule. If you want the created bundles to be installed, you may want to add this rule to your Makefile.am: install-exec-hook: APP_NAME_bundle rm -rf $(DESTDIR)$(prefix)/Applications/APP_NAME.app mkdir -p $(DESTDIR)$(prefix)/Applications/ cp -r $< /$(DESTDIR)$(prefix)Applications/ This rule takes the Bundle created by the rule from step 3 and installs them into $(DESTDIR)$(prefix)/Applications/. Again, if you want to install multiple applications, you will have to augment the make rule accordingly. ============================================================================== Using the Simple DirectMedia Layer with Project Builder ============================================================================== These instructions are for using Apple's Project Builder IDE to build SDL applications. - First steps The first thing to do is to unpack the PBProjects.tar.gz archive in the top level SDL directory (where the PBProjects.tar.gz archive resides). Because Stuffit Expander will unpack the archive into a subdirectory, you should unpack the archive manually from the command line: cd [path_to_SDL_source] tar zxf PBProjects.tar.gz This will create a new folder called PBProjects, which you can browse normally from the Finder. - Building the Framework The SDL Library is packaged as a framework bundle, an organized relocatable folder heirarchy of executible code, interface headers, and additional resources. For practical purposes, you can think of a framework as a more user and system-friendly shared library, whose library file behaves more or less like a standard UNIX shared library. To build the framework, simply open the framework project and build it. By default, the framework bundle "SDL.framework" is installed in ~/Library/Frameworks. Therefore, the testers and project stationary expect it to be located there. However, it will function the same in any of the following locations: ~/Library/Frameworks /Local/Library/Frameworks /System/Library/Frameworks - Build Options There are two "Build Styles" (See the "Targets" tab) for SDL. "Deployment" should be used if you aren't tweaking the SDL library. "Development" should be used to debug SDL apps or the library itself. - Building the Testers Open the SDLTest project and build away! - Using the Project Stationary Copy the stationary to the indicated folders to access it from the "New Project" and "Add target" menus. What could be easier? - Setting up a new project by hand Some of you won't want to use the Stationary so I'll give some tips: * Create a new "Cocoa Application" * Add src/main/macosx/SDLMain.m , .h and .nib to your project * Remove "main.c" from your project * Remove "MainMenu.nib" from your project * Add "$(HOME)/Library/Frameworks/SDL.framework/Headers" to include path * Add "$(HOME)/Library/Frameworks" to the frameworks search path * Add "-framework SDL -framework Foundation -framework AppKit" to "OTHER_LDFLAGS" * Set the "Main Nib File" under "Application Settings" to "SDLMain.nib" * Add your files * Clean and build - Building from command line Use pbxbuild in the same directory as your .pbproj file - Running your app You can send command line args to your app by either invoking it from the command line (in *.app/Contents/MacOS) or by entering them in the "Executibles" panel of the target settings. - Implementation Notes Some things that may be of interest about how it all works... * Working directory As defined in the SDL_main.m file, the working directory of your SDL app is by default set to its parent. You may wish to change this to better suit your needs. * You have a Cocoa App! Your SDL app is essentially a Cocoa application. When your app starts up and the libraries finish loading, a Cocoa procedure is called, which sets up the working directory and calls your main() method. You are free to modify your Cocoa app with generally no consequence to SDL. You cannot, however, easily change the SDL window itself. Functionality may be added in the future to help this.
