Hey,

I have a JPanel with custom painting on it. If tell the mouseMoved()
method to repaint() the JPanel it repaints() the whole JFrame,
including all sorts of other components beside the JPanel in it,
inside the Panel.
Any idea why this happens or how I could solve the problem? Thanks for
your help in advance.

Greetings

the right question is - why do you want to repaint your panel on
mouseMoved()???

Simple: if you call repaint() on a JFrame, it repaints the (whole) JFrame.
What do you want to repaint, if not the whole JFrame?

Try repainting just the JPanel.

panel.repaint() ;

This would repaint the JPanel. If you have your own custom painting
inside a paintComponent method, this will be called.
