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.
