Question about JInternalFrame

[Alexandre Baldo]

Hi, guys!
I'm working on a little project and I having some difficulties using JInternalFrame
Let me explain what's going on:

I have a JDesktopPane and I am adding a JInternalFrame (A) to it.
Inside (A) I have a JButton that make an instance of another JInternalFrame (B) and add it to the JDesktopPane as well.

The questions are:

1) How can I make (A) accessible only when (B) is closed???

2) Why (B).setSelected(true) and (B).moveToFront() doesn't work in this case?? (B) always appears behind (A)...

Thank's!!!

2) Why (B).setSelected(true) and (B).moveToFront() doesn't work in this case?? (B) always appears behind (A)...

Sorry guys! I just figured out what's going on with question #2!
I was doing this:

try {
  frame.moveToFront();
  frame.setSelected(true);
} catch (PropertyVetoException e) {
  e.printStackTrace();
} 
desktop.add(frame);

BUT...... I was suposed to do desktop.add(frame); FIRST!

Now just left #1!

Thank's!

When the button is clicked, besides showing B you should call "setVisible(false)" on A. That will hide it.

Add an InternalFrameListener to B; extend InternalFrameAdapter for ease. Override "internalFrameClosed", and in it call "setVisible(true)" on A. That will show it again.

Thank's Rod!!

But I dont't want to make (A) invisible. I want (B) to be modal...
I'll try to instance (B) as a JDialog.
I was reading the API and I think it could work...

Thanks again!

It should work, but it will be modal for the entire application, not just A.
