JFrame needed for JPanel??

Just curious if JFrame is needed if your trying to use JPanel..

public class TestPanel extends JPanel{

Now somewhere after that do i need to make a new JFrame???

Yup, all applications can only display 'top level' components on your desktop; the Swing top level components are JFrame, JDialog and JWindow. You have to add your JPanel to one of these to be able to display it.

kind regards,

Yes. A JPanel is simply an area inside a window. You need to put that in a window. Whether that window is an JFrame or an Applet is up to you.
