问题
Wondering if there's a menu event I can bind to that's related to the currently selected menu item? By menu item I mean the items that show up in a popup menu like New, Open, Save, etc.
Use case: I would like to update a statusbar area of our application with a description of the currently selected menu item.
Any ideas appreciated.
Thank you, Malcolm

You need to bind to the <<MenuSelect>> event.

There's an <Enter> event that is triggered when the mouse pointer enters a widget's space. Depending on how you're building your menu, you may be able to use it.
