XUnmapWindow(3X11)      COMMAND REFERENCE      XUnmapWindow(3X11)



NAME
     XUnmapWindow, XUnmapSubwindows - unmap windows

SYNOPSIS
     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.
