Function Documentation

Bool dmxBEDestroyWindow ( WindowPtr  pWindow  ) 

Destroy pWindow on the back-end server.

References _DMXScreenInfo::beDisplay, DMX_GET_WINDOW_PRIV, dmxScreens, and _dmxWinPriv::window.

Referenced by dmxBEDestroyWindowTree(), and dmxDestroyWindow().

void dmxChangeBorderWidth ( WindowPtr  pWindow,

)
Bool dmxChangeWindowAttributes ( WindowPtr  pWindow,
unsigned long  mask 
)
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.

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.

References _DMXScreenInfo::beDisplay, DMX_GET_WINDOW_PRIV, dmxCreateNonRootWindow(), dmxCreatePictureList(), dmxDoRestackWindow(), dmxDoSetShape(), dmxScreens, dmxSync(), _dmxWinPriv::hasPict, _dmxWinPriv::isShaped, _dmxWinPriv::mapped, _dmxWinPriv::restacked, and _dmxWinPriv::window.

Window dmxCreateRootWindow ( WindowPtr  pWindow  ) 
Bool dmxCreateWindow ( WindowPtr  pWindow  ) 
Bool dmxDestroyWindow ( WindowPtr  pWindow  ) 

Destroy pWindow on the back-end server. If any RENDER pictures were created, destroy them as well.

Initialize the private area for the window functions.

Bool dmxPositionWindow ( WindowPtr  pWindow,
int  x,
int  y 
)
Bool dmxRealizeWindow ( WindowPtr  pWindow  ) 

Realize pWindow on the back-end server. If the lazy window creation optimization is enabled, the window is only realized when it at least partially overlaps the screen.

void dmxResizeRootWindow ( WindowPtr  pRoot,

)

Change the location and size of the "root" window. Called from dmxConfigureRootWindow.

void dmxResizeScreenWindow ( ScreenPtr  pScreen,
int  x,
int  y,
int  w,
int  h 
)

Change the location and size of the "screen" window. Called from dmxConfigureScreenWindow().

References _DMXScreenInfo::beDisplay, dmxScreens, dmxSync(), and _DMXScreenInfo::scrnWin.

void dmxResizeWindow ( WindowPtr  pWindow,
int  x,
int  y,
unsigned int  w,
unsigned int  h,
WindowPtr  pSib 
)

Resize 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_RESIZE, DMX_WINDOW_OFFSCREEN, DMX_WRAP, dmxCreateAndRealizeWindow(), dmxResizeWindow(), dmxScreens, dmxSync(), dmxUpdateWindowInfo(), _dmxWinPriv::mapped, _dmxWinPriv::offscreen, and _dmxWinPriv::window.

) [static]

Referenced by dmxWindowExposures().

void dmxWindowExposures ( WindowPtr  pWindow,
RegionPtr  prgn,
RegionPtr  other_exposed 
)

Handle exposures on pWindow. Since window exposures are handled in DMX, the events that are generated by the back-end server are redundant, so we eat them here.
