XMapWindow(3X11)
X11R6
NAME
  XMapWindow, XMapRaised, XMapSubwindows - map windows

SYNOPSIS
  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 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 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.

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