XDestroyWindow(3X11)RISC/os Reference Manual XDestroyWindow(3X11)



NAME
     XDestroyWindow, XDestroySubwindows - destroy windows

SYNTAX
     XDestroyWindow(display, w)
           Display *display;
           Window w;

     XDestroySubwindows(display, w)
           Display *display;
           Window w;

ARGUMENTS
     display   Specifies the connection to the X server.

     w         Specifies the window.

DESCRIPTION
     The XDestroyWindow function destroys the specified window as
     well as all of its subwindows and causes the X server to
     generate a DestroyNotify event for each window.  The window
     should never be referenced again.  If the window specified
     by the w argument is mapped, it is unmapped automatically.
     The ordering of the DestroyNotify events is such that for
     any given window being destroyed, DestroyNotify is generated
     on any inferiors of the window before being generated on the
     window itself.  The ordering among siblings and across
     subhierarchies is not otherwise constrained.  If the window
     you specified is a root window, no windows are destroyed.
     Destroying a mapped window will generate Expose events on
     other windows that were obscured by the window being des-
     troyed.

     XDestroyWindow can generate a BadWindow error.

     The XDestroySubwindows function destroys all inferior win-
     dows of the specified window, in bottom-to-top stacking
     order.  It causes the X server to generate a DestroyNotify
     event for each window.  If any mapped subwindows were actu-
     ally destroyed, XDestroySubwindows causes the X server to
     generate Expose events on the specified window.  This is
     much more efficient than deleting many windows one at a time
     because much of the work need be performed only once for all
     of the windows, rather than for each window.  The subwindows
     should never be referenced again.

     XDestroySubwindows can generate a BadWindow error.

DIAGNOSTICS
     BadWindow A value for a Window argument does not name a
               defined Window.
