Thread: Problem with saving image to a file

Yes, but this code does not work maybe it requires JPanel.

The main method is in another class (GUIApp class)

So, can I send my application as a jar file to your email?

Thank you a lot. It works now

The problem was

<f.paint( graphics2D );

The correct is

<drawingPanel.paint( graphics2D );>
