\section{\class{wxMenuEvent}}\label{wxmenuevent}
This class is used for a variety of menu-related events. Note that
these do not include menu command events, which are
handled using \helpref{wxCommandEvent}{wxcommandevent} objects.
The handler \helpref{wxFrame::OnMenuHighlight}{wxframeonmenuhighlight} displays help
text in the first field of the status bar.

functions that take a wxMenuEvent argument.
