- No, not usually. - Launch times are slow, maybe prebinding will help - Direct framebuffer access has some artifacts, maybe a driver issue - Cursor in 8 bit modes is screwy */ #include #include #include #include #include "SDL_video.h" #include "SDL_error.h" #include "SDL_syswm.h" #include "SDL_sysvideo.h" #include "SDL_pixels_c.h" #include "SDL_events_c.h" /* This is a workaround to directly access NSOpenGLContext's CGL context */ /* We need to do this in order to check for errors */ @interface NSOpenGLContext (CGLContextAccess) - (CGLContextObj) cglContext; @end @implementation NSOpenGLContext (CGLContextAccess) - (CGLContextObj) cglContext; { return _contextAuxiliary; } @end typedef struct SDL_PrivateVideoData { CGDirectDisplayID display; /* 0 == main display */ CFDictionaryRef mode; CFDictionaryRef save_mode; CFArrayRef mode_list; CGDirectPaletteRef palette; NSOpenGLContext *gl_context; Uint32 width, height, bpp; Uint32 flags; SDL_bool video_is_set; /* tell if the video mode was set */ /* Window-only fields */ NSWindow *window; NSQuickDrawView *view; } SDL_PrivateVideoData ; #define _THIS SDL_VideoDevice *this #define display_id (this->hidden->display) #define mode (this->hidden->mode) #define save_mode (this->hidden->save_mode) #define mode_list (this->hidden->mode_list) #define palette (this->hidden->palette) #define glcontext (this->hidden->glcontext) #define objc_video (this->hidden->objc_video) #define gl_context (this->hidden->gl_context) #define device_width (this->hidden->width) #define device_height (this->hidden->height) #define device_bpp (this->hidden->bpp) #define mode_flags (this->hidden->flags) #define video_set (this->hidden->video_is_set) #define qz_window (this->hidden->window) #define windowView (this->hidden->view) /* Interface for hardware fill not (yet) in the public API */ int CGSDisplayHWFill (CGDirectDisplayID id, unsigned int x, unsigned int y, unsigned int w, unsigned int h, unsigned int color); int CGSDisplayCanHWFill (CGDirectDisplayID id); /* Bootstrap functions */ static int QZ_Available (); static SDL_VideoDevice* QZ_CreateDevice (int device_index); static void QZ_DeleteDevice (SDL_VideoDevice *device); /* Initialization, Query, Setup, and Redrawing functions */ static int QZ_VideoInit (_THIS, SDL_PixelFormat *video_format); static SDL_Rect** QZ_ListModes (_THIS, SDL_PixelFormat *format, Uint32 flags); static void QZ_UnsetVideoMode (_THIS); static SDL_Surface* QZ_SetVideoMode (_THIS, SDL_Surface *current, int width, int height, int bpp, Uint32 flags); static int QZ_ToggleFullScreen (_THIS, int on); static int QZ_SetColors (_THIS, int first_color, int num_colors, SDL_Color *colors); static void QZ_DirectUpdate (_THIS, int num_rects, SDL_Rect *rects); static void QZ_UpdateRects (_THIS, int num_rects, SDL_Rect *rects); static void QZ_VideoQuit (_THIS); /* Hardware surface functions (for fullscreen mode only) */ static int QZ_FillHWRect (_THIS, SDL_Surface *dst, SDL_Rect *rect, Uint32 color); static int QZ_LockHWSurface(_THIS, SDL_Surface *surface); static void QZ_UnlockHWSurface(_THIS, SDL_Surface *surface); static void QZ_FreeHWSurface (_THIS, SDL_Surface *surface); /* static int QZ_FlipHWSurface (_THIS, SDL_Surface *surface); */ /* Gamma Functions */ static int QZ_SetGamma (_THIS, float red, float green, float blue); static int QZ_GetGamma (_THIS, float *red, float *green, float *blue); static int QZ_SetGammaRamp (_THIS, Uint16 *ramp); static int QZ_GetGammaRamp (_THIS, Uint16 *ramp); /* OpenGL functions */ static int QZ_SetupOpenGL (_THIS, int bpp, Uint32 flags); static void QZ_TearDownOpenGL (_THIS); static void* QZ_GL_GetProcAddress (_THIS, const char *proc); static int QZ_GL_GetAttribute (_THIS, SDL_GLattr attrib, int* value); static int QZ_GL_MakeCurrent (_THIS); static void QZ_GL_SwapBuffers (_THIS); static int QZ_GL_LoadLibrary (_THIS, const char *location); /* Private function to warp the cursor (used internally) */ static void QZ_PrivateWarpCursor (_THIS, int fullscreen, int h, int x, int y); /* Cursor and Mouse functions */ static void QZ_FreeWMCursor (_THIS, WMcursor *cursor); static WMcursor* QZ_CreateWMCursor (_THIS, Uint8 *data, Uint8 *mask, int w, int h, int hot_x, int hot_y); static int QZ_ShowWMCursor (_THIS, WMcursor *cursor); static void QZ_WarpWMCursor (_THIS, Uint16 x, Uint16 y); static void QZ_MoveWMCursor (_THIS, int x, int y); static void QZ_CheckMouseMode (_THIS); /* Event functions */ static void QZ_InitOSKeymap (_THIS); static void QZ_PumpEvents (_THIS); /* Window Manager functions */ static void QZ_SetCaption (_THIS, const char *title, const char *icon); static void QZ_SetIcon (_THIS, SDL_Surface *icon, Uint8 *mask); static int QZ_IconifyWindow (_THIS); static SDL_GrabMode QZ_GrabInput (_THIS, SDL_GrabMode grab_mode); /*static int QZ_GetWMInfo (_THIS, SDL_SysWMinfo *info);*/
