This class is used to represent a variety of menu-related events such as
highlighting, opening and closing items. Note that the commonest event
to be handled from menus – that of actually choosing a menu item – is
not a MenuEvent but a CommandEvent, captured by
using evt_menu.
The default handler for evt_menu_highlight displays help text in the
first field of the status bar.
To process a menu event, use these event handler macros to direct input to member functions that take a MenuEvent argument. They can only be processed by a menubar’s frame.
| evt_menu_open() { | event | ... } | A menu is about to be opened. On Windows,this is only sent once for each navigation of the menubar (up until all menus have closed). |
| evt_menu_close() { | event | ... } | A menu has been just closed. |
| evt_menu_highlight(id) { | event | ... } | The menu item with thespecified id has been highlighted: used to show help prompts in the status barby Frame |
| evt_menu_highlight_all() { | event | ... } | A menu item has beenhighlighted, i.e. the currently selected menu item has changed. |
