How to make JPopupMenu invisible?

I have added to a JTextField a JPopupMenu.
Unfortunatelly, when i change the focus from JTextField, or when i "minimize" the window, the JPopupMenu still is visible.
I need to make it invisible if JTextField is loosing the focus.
How can i do this?

I guess you can add a FocusListener to the text field. When the focusLost() event is fired you get the source which will be the text field and then get the parent which should be the popup menu which you can then hide manually.

Good to know I wasted my time answering a question that has already been answered. That won't happen again.
