1 | \section{\class{wxMenuEvent}}\label{wxmenuevent} |
| 2 | ||
| 3 | This class is used for a variety of menu-related events. Note that | |
| f4fcc291 JS |
4 | these do not include menu command events, which are |
| 5 | handled using \helpref{wxCommandEvent}{wxcommandevent} objects. | |
| 6 | ||
| 7 | The handler \helpref{wxFrame::OnMenuHighlight}{wxframeonmenuhighlight} displays help | |
| 8 | text in the first field of the status bar. | |
