From c944e03efaa41065beca04a5b2ab6f48e70490e8 Mon Sep 17 00:00:00 2001 From: Sam Lantinga Date: Tue, 22 Jan 2002 18:46:28 +0000 Subject: [PATCH] Date: Sat, 19 Jan 2002 17:24:32 -0500 (EST) From: Darrell Walisser Subject: SDL Quartz video update -better mouse motion events -fixed minification bugs (except OpenGL) -fixed QZ_SetGamma for correct semantics -fade/unfade display before/after rez switch -experimental obscured-check/blind-copy code The obscured code, while it speeds up window drawing substantially, isn't ready yet. The reason is that there doesn't (yet) seem to be a way to know when the window is dragged or when the window suddenly comes to the foreground. Since Carbon windows seem to allow detection of such things, I suspect it is possible through some window server API. Cocoa(NSWindow) has no functions for such things, AFAIK. --- src/video/quartz/SDL_QuartzEvents.m | 125 ++++-- src/video/quartz/SDL_QuartzVideo.h | 122 ++++-- src/video/quartz/SDL_QuartzVideo.m | 589 ++++++++++++++++++++++++---- src/video/quartz/SDL_QuartzWM.m | 128 ++++-- src/video/quartz/SDL_QuartzWindow.m | 71 +++- 5 files changed, 855 insertions(+), 180 deletions(-) diff --git a/src/video/quartz/SDL_QuartzEvents.m b/src/video/quartz/SDL_QuartzEvents.m index c7dadac74..8d477abfd 100644 --- a/src/video/quartz/SDL_QuartzEvents.m +++ b/src/video/quartz/SDL_QuartzEvents.m @@ -19,6 +19,7 @@ Sam Lantinga slouken@libsdl.org */ +#include #include "SDL_QuartzKeys.h" @@ -305,7 +306,13 @@ static void QZ_DoDeactivate (_THIS) { static void QZ_PumpEvents (_THIS) { - NSDate *distantPast; + + static NSPoint lastMouse; + NSPoint mouse, saveMouse; + Point qdMouse; + CGMouseDelta dx, dy; + + NSDate *distantPast; NSEvent *event; NSRect winRect; NSRect titleBarRect; @@ -314,10 +321,36 @@ static void QZ_PumpEvents (_THIS) pool = [ [ NSAutoreleasePool alloc ] init ]; distantPast = [ NSDate distantPast ]; - winRect = NSMakeRect (0, 0, SDL_VideoSurface->w + 1, SDL_VideoSurface->h + 1); + winRect = NSMakeRect (0, 0, SDL_VideoSurface->w, SDL_VideoSurface->h); titleBarRect = NSMakeRect ( 0, SDL_VideoSurface->h, SDL_VideoSurface->w, SDL_VideoSurface->h + 22 ); - + + if (currentGrabMode != SDL_GRAB_ON) { /* if grabbed, the cursor can't move!
