XUnmapWindow(XS)  X Version 11 (Release 5) 6 January 1993   XUnmapWindow(XS)


 Name

    XUnmapWindow - 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 win-
    dows 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 form-
    erly obscured windows.  Using this function is much more efficient than
    unmapping multiple windows one at a time because the server needs to per-
    form 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 Win-
                   dow.
