In case you want the code to execute before the menu is visible so you can configure the popup you can add a PopupMenuListener to the JPopup. It supports 3 events:
- popupMenuCanceled
- popupMenuWillBecomeInvisible
- popupMenuWillBecomeVisible

You should register a property change listener.
In the listener you should check whether the new value of the event is
Boolean.TRUE.
