Hide JInternalFrame from JPanel

I'm building a JPanel and it is given to a JInternalFrame. Now I want that if someone clicks on the X button of the JInternalFrame it is hidden, not closed. The Problem is that I have to implement this function in the JPanel and I don't have access to the JInternalFrame.

Is this possible?

I know from the JInternalFrame it can be realized with setDefaultCloseOperation(HIDE_ON_CLOSE); but I don't know how to do it from the JPanel. Of course I searched in SO but I did not found anything that fits for my case.

Another Question, just for understanding: what is happening when you click on the X button? Is the dispose() function called? I'm new to Java Swing and interested how it works.

You can use the SwingUtilities class to find the parent container.

Something like:

JInternalFrame frame = (JInternalFrame)SwingUtilities.ancestorOfClass(JInternalFrame.class, thePanel);
