XReparentWindow 3X11 __xorgversion__ XLIB FUNCTIONS XReparentWindow reparent windows int XReparentWindow ( Display *display , Window w , Window parent , int x , int y ); display Specifies the connection to the X server. parent Specifies the parent window. w Specifies the window. x y Specify the x and y coordinatesof the position in the new parent window. 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 window is placed in the stacking order on top with respect to sibling windows. After reparenting the specified window,  XReparentWindow  causes the X server to generate a  ReparentNotify  event. The override_redirect 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 window. 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.  BadWindow  A value for a Window argument does not name a defined Window.
