Question

What is the difference between a JFrame and a JDialog?

Why can\'t we use setDefaultCloseOperation(JDialog.EXIT_ON_CLOSE); for a JD

Answer 1

You can also use setModal(boolean t); This only works on JDialog. User must operate on JDialog not other window. If they wanna operate owner windows, they must shut down this JDialog.
