How to print an invisible JPanel.
Hello!
I try to print a new instance of a JPanel with the Printable interface. But the output page is everytime empty.
When I put the instance of the JPanel into a new JFrame and open this frame with a setVisible(true), the output is perfect.
My theory is, that the JPanel will not be painted, when it's not will be showed.
Is it possible, that I can print my JPanel without creating and showing a JFrame?
Thanks for your answers!
PS: And sorry for this mad english!
