Quartz target shouldn't crash if an event thread is used. (SDL_INIT_EVENTTHREAD still doesn't work, but the crash is gone...)

To: From: Christian Walther <> Date: Thu, 15 Dec 2005 21:19:53 +0100 Subject: [SDL] More mouse enhancements for Mac OS X The attached patch brings two more enhancements to mouse handling on Mac OS X (Quartz): 1. Currently, after launching an SDL application, SDL's notion of the mouse position is stuck in the top left corner (0,0) until the first time the mouse is moved. That's because the UpdateMouse() function isn't implemented in the Quartz driver. This patch adds it. 2. When grabbing input while the mouse cursor is hidden, the function CGAssociateMouseAndMouseCursorPosition(0) is called, which prevents the system's notion of the mouse location from moving (and therefore leaving the SDL window) even when the mouse is moved. However, apparently the Wacom tablet driver (and maybe other special pointing device drivers) doesn't care about that setting and still allows the mouse location to go outside of the window. Interestingly, the system cursor, which is made visible by the existing code in SDL in that case, does not follow the mouse location, but appears in the middle of the SDL window. The mouse location being outside of the window however means that mouse button events go to background applications (or the dock or whatever is there), which is very confusing to the user who sees no cursor outside of the SDL window. I have not found any way of intercepting these events (and that's probably by design, as "normal" applications shouldn't prevent the user from bringing other applications' windows to the front by clicking on them). An idea would be placing a fully transparent, screen-filling window in front of everything, but I fear that this might affect rendering performance (by doing unnecessary compositing, using up memory, or whatever). The deluxe solution to the problem would be talking to the tablet driver using AppleEvents to tell it to constrain its mapped area to the window (see Wacom's "TabletEventDemo" sample app,, but I think that the bloat that solution would add to SDL would outweigh its usefulness. What I did instead in my patch is reassociating mouse and cursor when the mouse leaves the window while an invisible grab is in effect, and restoring the grab when the window is entered. That way, the grab can still be effectively broken by a tablet, but at least it's obvious to the user that it is broken. That change is minimal - it doesn't affect operation with a mouse (or a trackpad), and the code that it adds is not executed on every PumpEvents() call, only when entering and leaving the window. Unless there are any concerns about the patch, please apply. Feel free to shorten the lengthy comment in SDL_QuartzEvents.m if you think it's too verbose. Thanks -Christian

To: From: Christian Walther <> Date: Wed, 28 Dec 2005 12:13:20 +0100 Subject: [SDL] Fix for opening documents on Mac OS X < 10.4 The current code in SDLMain.m that transforms documents opened from the Finder into command-line arguments (introduced in revision 1.14, 2005-08-11) uses the methods -[NSString lengthOfBytesUsingEncoding:] and -[NSString getCString:maxLength:encoding:], which are only available in Mac OS X 10.4. Compiling this code on 10.3 produces warnings, and running it (i.e. starting an SDL application by opening a document) leads to weird behavior which I didn't investigate in detail ("*** -[NSCFString lengthOfBytesUsingEncoding:]: selector not recognized" is printed to the console log, and the SDL window never opens). The attached patch removes the offending calls and uses -[NSString UTF8String] instead, which is available everywhere. Tested on 10.3.9, and I see no reason why it shouldn't also work on 10.2 and 10.4. Two further comments: * The comment above the -[SDLMain application: openFile:] implementation says "You need to have a CFBundleDocumentsType section in your Info.plist to get this message, apparently." This is not the case in my experience - it worked just fine with a hand-built bare-bones application consisting only of, without any Info.plist (although you have to press the option and command keys for such an application to accept a dragged file). * I took the liberty of cleaning up another area of SDLMain.m: I changed "CustomApplicationMain (argc, argv)" to "CustomApplicationMain (int argc, char **argv)". This avoids the "type of `argv' defaults to `int'" warnings, and I'm not sure if leaving out the types could cause problems on platforms where an int and a char** aren't of the same size. -Christian

Bumped windib's priority above DirectX, since both DirectDraw and DirectInput seem to be giving people issues on newer Windows and DX revisions. We'll see if this is just a temporary fix or not... :/ --ryan.

Additionally I've modifed the order the wait for vsync is called as it should be after the screen bank switching.

Otherwise, the next mouse motion event is wrong. Please apply. Thanks Christian
