Drawing on a Panel

[jonbink16]

The drawing of an Image on a panel wont show up until I minimize and then re-open the JFrame. Also, the mousePressed and mouseReleased functions wont work until I resize the JFrame. Is there anything that I need to add to the code to make me not have to do this?

You should provide context in the form of a SSCCE - concentrating on one thing at a time. I can render a guess that you are adding components after the JFrame is visible, but can only guess given the amount of information.

I think this will work. When the window is ready then it does the following code.

panel.addWindowListener(new WindowAdapter() {
	public void windowActivated(WindowEvent e) {
		repaint();
	}
});

I hope this works.

That won't come close to solving the original poster's problem, sorry. He possibly is not calling repaint() inside of his MouseListener, but til he posts his code, who knows.

I have had this problem before and I believe this code does work. though it may not be repaint() that he needs to call. But yes for anyone who had not had this problem before would need context.
