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

20 | ||
21 | To process a menu event, use these event handler macros to direct input to member | |
22 | functions that take a wxMenuEvent argument. They can only be processed by | |
23 | a menubar's frame. | |

62 | ||
63 | \constfunc{int}{GetMenuId}{\void} | |
