XUnmapWindow(3)                                                XUnmapWindow(3)




NAME

       XUnmapWindow, XUnmapSubwindows - unmap windows


SYNTAX

       int XUnmapWindow(Display *display, Window w);

       int XUnmapSubwindows(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 process-
       ing 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 gen-
       erate an UnmapNotify event on each subwindow and Expose events on  for-
       merly  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.
