NAME

XMapWinow, XMapRaised, XMapSubwindows - map windows

SYNTAX

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

XMapRaised(display, w)
      Display *display;
      Window w;

XMapSubwindows(display, w)
      Display *display;
      Window w;

ARGUMENTS

display   Specifies the connection to the XWIN 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 XWIN server generates a MapRequest event, and the XMapWindow function does not map the window. Otherwise, the window is mapped, and the XWIN server generates a MapNotify event.

     If the window becomes viewable and no earlier contents for
     it are remembered, the XWIN server tiles the window with its
     background.  If the window's background is undefined, the
     existing screen contents are not altered, and the XWIN
     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 infe-
     riors.

     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 speci-
fied window to the top of the stack.

XMapRaised can generate a BadWindow error.

The XMapSubwindows function maps all subwindows for a speci-
fied window in top-to-bottom stacking order.  The XWIN
server generates Expose events on each newly displayed win-
dow.  This may be much more efficient than mapping many win-
dows 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 Window.
