Java Window Frames

Dear Sirs,
I have 2 windows frames. Let's put it this way: a parent and a child.
How can I prevent access to the parent frame when the child is active (called from the parent). In other words, open it in read mode.

Another scenario, is that to only keep the child active and close the parent.

I am new to Java.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Generally speaking, you should only have one JFrame class per app. Additional windows will be some kind of dialog. If you use a JOptionPane for this, it is by definition modal and the functionality will be as you desire. If you want to use a JDialog subclass, call setModal(true)

Yes. Use a JDialog much like a JFrame
