Popup Menu Example

This example demonstrates how to popup a menu.

A menu can be popped up in 2-ways. The first is by declaring the menu as a child of a widget and setting the ‘context_menu’ attribute to True. The second method is by creating the menu on-demand, and then invoking it’s ‘popup()’ method to show the menu at the current mouse location.

Tip

To see this example in action, download it from popup_menu and run:

$ enaml-run popup_menu.enaml
