XMapWindow 3X11 __xorgversion__ XLIB FUNCTIONS XMapWindow XMapRaised XMapSubwindows map windows int XMapWindow ( Display *display , Window w ); int XMapRaised ( Display *display , Window w ); int XMapSubwindows ( Display *display , Window w ); display Specifies the connection to the X server. w Specifies the window. The  XMapWindow  function maps the window and all of its subwindows that have had map requests. Mapping a window that has an unmapped ancestor does not display the window but marks it as eligible for display when the ancestor becomes mapped. Such a window is called unviewable. When all its ancestors are mapped, the window becomes viewable and will be visible on the screen if it is not obscured by another window. This function has no effect if the window is already mapped. If the override-redirect of the window is  False  and if some other client has selected  SubstructureRedirectMask  on the parent window, then the X server generates a  MapRequest  event, and the  XMapWindow  function does not map the window. Otherwise, the window is mapped, and the X server generates a  MapNotify  event. If the window becomes viewable and no earlier contents for it are remembered, the X server tiles the window with its background. If the window's background is undefined, the existing screen contents are not altered, and the X server generates zero or more  Expose  events. If backing-store was maintained while the window was unmapped, no  Expose  events are generated. If backing-store will now be maintained, a full-window exposure is always generated. Otherwise, only visible regions may be reported. Similar tiling and exposure take place for any newly viewable inferiors. If the window is an  InputOutput  window,  XMapWindow  generates  Expose  events on each  InputOutput  window that it causes to be displayed. If the client maps and paints the window and if the client begins processing events, the window is painted twice. To avoid this, first ask for  Expose  events and then map the window, so the client processes input events as usual. The event list will include  Expose  for each window that has appeared on the screen. The client's normal response to an  Expose  event should be to repaint the window. This method usually leads to simpler programs and to proper interaction with window managers.  XMapWindow  can generate a  BadWindow  error. The  XMapRaised  function essentially is similar to  XMapWindow  in that it maps the window and all of its subwindows that have had map requests. However, it also raises the specified window to the top of the stack.  XMapRaised  can generate a  BadWindow  error. The  XMapSubwindows  function maps all subwindows for a specified window in top-to-bottom stacking order. The X server generates  Expose  events on each newly displayed window. This may be much more efficient than mapping many 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.  XMapSubwindows  can generate a  BadWindow  error.  BadWindow  A value for a Window argument does not name a defined Window.
