                                6 January 1993


 Name

    XReparentWindow - reparent windows

 Syntax


    XReparentWindow(display, w, parent, x, y)
          Display *display;
          Window w;
          Window parent;
          int x, y;


 Arguments


    display  Specifies the connection to the X server.

    parent   Specifies the parent window.

    w        Specifies the window.

    x
    y        Specify the x and y coordinates of the position in the new
             parent window.

 Description

    If the specified window is mapped, XReparentWindow automatically performs
    an UnmapWindow request on it, removes it from its current position in the
    hierarchy, and inserts it as the child of the specified parent.  The win-
    dow is placed in the stacking order on top with respect to sibling win-
    dows.

    After reparenting the specified window, XReparentWindow causes the X
    server to generate a ReparentNotify event.  The overrideredirect member
    returned in this event is set to the window's corresponding attribute.
    Window manager clients usually should ignore this window if this member
    is set to True.  Finally, if the specified window was originally mapped,
    the X server automatically performs a MapWindow request on it.

    The X server performs normal exposure processing on formerly obscured
    windows.  The X server might not generate Expose events for regions from
    the initial UnmapWindow request that are immediately obscured by the
    final MapWindow request.  A ``BadMatch'' error results if:

    +  The new parent window is not on the same screen as the old parent win-
       dow.

    +  The new parent window is the specified window or an inferior of the
       specified window.

    +  The new parent is InputOnly and the window is not.

    +  The specified window has a ParentRelative background, and the new
       parent window is not the same depth as the specified window.

    XReparentWindow can generate ``BadMatch'' and ``BadWindow'' errors.

 Diagnostics


    ``BadWindow''  A value for a Window argument does not name a defined Win-
                   dow.
