Python/Tkinter: bind to event related to currently selected menu item

Question

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

Answer 1

您需要绑定到<<MenuSelect>>事件。

Answer 2

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.
