DESCRIPTION
The 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 ances‐
tor 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 and if some other client has
selected on the parent window, then the X server generates a event, and
the function does not map the window. Otherwise, the window is mapped,
and the X server generates a 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 events. If backing-
store was maintained while the window was unmapped, no events are gen‐
erated. If backing-store will now be maintained, a full-window expo‐
sure is always generated. Otherwise, only visible regions may be
reported. Similar tiling and exposure take place for any newly view‐
able inferiors.
If the window is an window, generates events on each 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 events and then map the window, so the
client processes input events as usual. The event list will include
for each window that has appeared on the screen. The client's normal
response to an event should be to repaint the window. This method usu‐
ally leads to simpler programs and to proper interaction with window
managers.
can generate a error.
The function essentially is similar to 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.
can generate a error.
The function maps all subwindows for a specified window in top-to-bot‐
tom stacking order. The X server generates events on each newly dis‐
played window. 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.
can generate a error.
DIAGNOSTICS
A value for a Window argument does not name a defined Window.
