Function Documentation

void dmxBECreateGC ScreenPtr  pScreen,
GCPtr  pGC
 

Create the GC on the back-end server.

Bool dmxBEFreeGC GCPtr  pGC  ) 
 

Free the pGC on the back-end server.

void dmxChangeClip GCPtr  pGC,
int  type,
pointer  pvalue,
int  nrects
 

Change the clip rects for a GC.

void dmxChangeGC GCPtr  pGC,
unsigned long  mask
 

Set the values in the graphics context on the back-end server associated with pGC's screen.

void dmxCopyClip GCPtr  pGCDst,
GCPtr  pGCSrc
 

Copy a GC's clip rects.

void dmxCopyGC GCPtr  pGCSrc,
unsigned long  changes,
GCPtr  pGCDst
 

Copy pGCSrc to pGCDst on the back-end server associated with pGCSrc's screen.

Bool dmxCreateGC GCPtr  pGC  ) 
 

Create a graphics context on the back-end server associated /a pGC's screen.

void dmxDestroyClip GCPtr  pGC  ) 
 

Destroy a GC's clip rects.

void dmxDestroyGC GCPtr  pGC  ) 
 

Destroy the graphics context, pGC and free the corresponding GC on the back-end server.

Bool dmxInitGC ScreenPtr  pScreen  ) 
 

Initialize the GC on pScreen, which currently involves allocating the GC private associated with this screen.

void dmxValidateGC GCPtr  pGC,
unsigned long  changes,
DrawablePtr  pDrawable
 

Validate a graphics context, pGC, locally in the DMX server and recompute the composite clip, if necessary.
