Java SE (Java Platform, Standard Edition)

Hello,
I added a JLabel to a JFrame's LayeredPane:

frame.getLayeredPane().add(label,100);

and putted the JLabel's text in the middle of the frame using this code:

label.setBounds(0, 0, frame.getWidth(), frame.getHeight());

Now I would like the JLabel to be centered in the JFrame automatically when the JFrame gets resized by the user. Is it possible?
I'm using the WindowStateListener:

frame.addWindowStateListener(new WindowStateListener() {
	public void windowStateChanged(WindowEvent e) {
		label.setBounds(0, 0, frame.getWidth(), frame.getHeight());
	}
});

but this only works when the JFrame is resized using the predefined window's button in the top-right corner.

I would like the JLabel to be resized when the user drags the borders too.

Thank you in advance.
