回答1:

When you create a JDialog you should be specifying the JFrame as the owner of the dialog, then you can use the getOwner() method of the dialog to get the frame reference at any time.

In you JDialog you should be able to use a WindowListener.

1. In the windowOpened event you hide the frame
2. in the windowClosed event you show the frame.
