JComboBox selection actions on mouse and enter only

I am driving some processing off of selections in a JComboBox.

The ItemListener goes into action when the user mouse clicks on an item (this is good), but also when an item is arrowed through (bad).

I want to wait until the person hits enter before starting my processing.

Ideally the JComboBox popup could close before the start of my processing.

The direction I am currently headed: I notice that when the mouse clicks, and when enter is hit, the JComboBox popup closes. Since these are the 2 user events I want to respond to, this fact interests me greatly. Is there any way to see and use the event of the popup closing?

Note: I don't care so much about the direction I am thinking now as much as a solution to the overall problem.
