Referenced by dmxBEDestroyWindowTree(), and dmxDestroyWindow().

void dmxChangeBorderWidth	(	WindowPtr	pWindow,
		unsigned int	width
	)

Change border width for pWindow to width pixels.

Bool dmxChangeWindowAttributes	(	WindowPtr	pWindow,
		unsigned long	mask
	)

Change the window attributes of pWindow.

Referenced by dmxChangeWindowAttributes(), and dmxScreenInit().

void dmxCopyWindow	(	WindowPtr	pWindow,
		DDXPointRec	ptOldOrg,
		RegionPtr	prgnSrc
	)

Move pWindow on the back-end server. Determine whether or not it is on or offscreen, and realize it if it is newly on screen and the lazy window creation optimization is enabled.

References _DMXScreenInfo::beDisplay, DMX_GET_WINDOW_PRIV, DMX_UNWRAP, DMX_UPDATE_COPY, DMX_WINDOW_OFFSCREEN, DMX_WRAP, dmxCopyWindow(), dmxCreateAndRealizeWindow(), dmxScreens, dmxSync(), dmxUpdateWindowInfo(), _dmxWinPriv::mapped, _dmxWinPriv::offscreen, and _dmxWinPriv::window.

Referenced by dmxCopyWindow(), and dmxScreenInit().

void dmxCreateAndRealizeWindow	(	WindowPtr	pWindow,
		Bool	doSync
	)

This function handles lazy window creation and realization. Window creation is handled by dmxCreateNonRootWindow(). It also handles any stacking changes that have occured since the window was originally created by calling dmxDoRestackWindow(). If the window is shaped, the shape is set on the back-end server by calling dmxDoSetShape(), and if the window has pictures (from RENDER) associated with it, those pictures are created on the back-end server by calling dmxCreatePictureList(). If doSync is TRUE, then dmxSync() is called.
