The purpose of this event type is so that you can keep track of such
events if you want to.
-@cindex @code{deiconify-frame} event
-@item (deiconify-frame (@var{frame}))
+@cindex @code{make-frame-visible} event
+@item (make-frame-visible (@var{frame}))
This kind of event indicates that the user deiconified @var{frame} using
the window manager. Its standard definition is @code{ignore}; since the
frame has already been iconified, Emacs has no work to do.
