XDestroySubwindows(3)


NAME

   XDestroyWindow, XDestroySubwindows - destroy windows

SYNTAX

   int XDestroyWindow(Display *display, Window w);

   int XDestroySubwindows(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 destroyed.

   XDestroyWindow can generate a BadWindow error.

   The XDestroySubwindows function destroys all inferior windows 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 actually 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.
