[JAVA] Close a JFrame Solved

Question

Hello,  I want to close a JFrame window with a quit button. I see how to handle the button event, but I don't know what to put to close this window.  Thank you for your help.

If you have instantiated an object of type JFrame and you manage it from another class, you do:

 monObjectJFrame.dispose();

If you handle the event inside your own class (which extends JFrame), you do:

 this.dispose();

It should normally work.

Hello, my (simple) problem is the following:
I have a JFrame with a JPanel that contains a button that opens another JFrame, which contains a JPanel with a button to close this window.

I would like to access the JFrame of my 2nd JPanel in order to be able to close it; my attempts have only managed to close the 1st JFrame.

How can I access the JFrame from a JPanel? There is no getJFrame() method.

((JFrame) tonSecondPanel.getTopLevelAncestor()).dispose() ;  It should work!
