XUnmapWindow(3X11)            SDK X11 R4.11MU05           XUnmapWindow(3X11)


NAME
       XUnmapWindow, XUnmapSubwindows - unmap windows

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

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

ARGUMENTS
       display   Specifies the connection to the X server.

       w         Specifies the window.

DESCRIPTION
       The XUnmapWindow function unmaps the specified window and causes the
       X server to generate an UnmapNotify event.  If the specified window
       is already unmapped, XUnmapWindow has no effect.  Normal exposure
       processing on formerly obscured windows is performed.  Any child
       window will no longer be visible until another map call is made on
       the parent.  In other words, the subwindows are still mapped but are
       not visible until the parent is mapped.  Unmapping a window will
       generate Expose events on windows that were formerly obscured by it.

       XUnmapWindow can generate a BadWindow error.

       The XUnmapSubwindows function unmaps all subwindows for the specified
       window in bottom-to-top stacking order.  It causes the X server to
       generate an UnmapNotify event on each subwindow and Expose events on
       formerly obscured windows.  Using this function is much more
       efficient than unmapping multiple windows one at a time because the
       server needs to perform much of the work only once, for all of the
       windows, rather than for each window.

       XUnmapSubwindows can generate a BadWindow error.

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