Java hide JFrame1 and JFrame2, when JFrame0 is deactivated?

is there a way to hide all the other JFrames of my application, when the user clicks out of the "mainFrame"?

I tried with this

   public void windowActivated(WindowEvent we) {
        frame1.setVisible(true);
        frame.setVisible(true);
    }

    public void windowDeactivated(WindowEvent we) {
        frame1.setVisible(false);
        frame2.setVisible(false);
    }`

but this doesn't work. All of my Windows start blinking. I cannot set JFrame2 unfocusable.

Is there any other way to do this?

The non-modal dialog suggestion in this answer is one way to go. See also this answer elsewhere.

If for some reason you need to continue using frames, you can minify them with

frame1.setState(Frame.ICONIFIED)

and raise them with 

frame1.setState(Frame.NORMAL)

Handle these in a code block like:

frame0.addWindowStateListener(new WindowStateListener() {

        @Override
        public void windowStateChanged(WindowEvent e) {
                // handle change
        }
    });

as described in this question's answers.

If you want to close all frames when the frame0 is closed, you can use:

frame0.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

to exit the program and close all frames when the frame0 is closed. If you are just hiding on close use a window listener. You can use frame1.setVisible(false) in your WindowListener.

Use non-modal dialogs instead and the problem is sorted by default.

import javax.swing.*;

class TestDialogMinimize {

    public static void main(String[] args) {
        Runnable r = new Runnable() {
            public void run() {
                JFrame f = new JFrame("Has a Dialog");

                f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                f.setSize(400,400);

                JDialog d = new JDialog(f);
                d.setSize(200,200);
                f.setVisible(true);
                d.setVisible(true);
            }
        };
        SwingUtilities.invokeLater(r);
    }
}
