Hey here's my code for functioning like MS Paint. But JLabels are just not visible. Please Help.

		frame.getContentPane().add(panel);
		panel.setLayout(new BorderLayout());
		panel.add(paint);
		frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
		frame.setVisible(true);
		paint.getComponent(0).requestFocus();
	}

Probably because you override paint rather than paintComponent. paint also handles painting of children (eg lables ina child panel!), borders etc, and should not normally be overridden. paintComponent just handles the painting of the content area, and is the one you normally override.

Yes dat was exactly the problem. I never knew paintComponent ever existed. Now I will try to explore and learn it. Thanks a lot James!!
