minimizing the jframe window with a jbutton click

I know to minimize the jframe, I need to use setExtendedState(JFrame.ICONIFIED);
But what I am trying to figure out is how to get to the frame. This dialog is child of a parent dialog. Here is the Constructor.

    public EdiBaseDialog(EdiDialogHandler edh, Frame parent, TCSession theSession) {
      super(parent, false);
      session = theSession;
      createDialog();
   }

So when I try to add setExtendedState(JFrame.ICONIFIED) command in my jbutton actionPerformed. Which is in a JPanel Method.

I do not know how to address the frame.

??.setState(JFrame.ICONFIED);

What you need to do is go up in the component hierarchy until you arrive at the Frame. There are already helper methods in Swing to do this. Try SwingUtilties:

SwingUtilities.getAncestorOfClass(JFrame.class, this);

(Where 'this' can be any component in the hierarchy) Of course this will only be of use if your dialogs are forming a proper hierarchy (no dialogs using a NULL owner. If thats the case, you have to pass in the Frame through some method or constructor.

Call Dialog.getOwner() from within the dialog.
