XMapWindow(3X11)		XLIB FUNCTIONS		     XMapWindow(3X11)



NAME
       XMapWindow, XMapRaised, XMapSubwindows - map windows

SYNTAX
       int XMapWindow(Display *display, Window w);

       int XMapRaised(Display *display, Window w);

       int XMapSubwindows(Display *display, Window w);

ARGUMENTS
       display	 Specifies the connection to the X server.

       w	 Specifies the window.

DESCRIPTION
       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 pro-
       cessing 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 usu-
       ally 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.

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