Please help Re: Oval shape does not display 13 Years Ago by NormR1 Is the JPanel added after the GUI is made visible? Try calling setVisible after adding the JPanel. Re: Oval shape does not display 13 Years Ago by NormR1 There could be a conflict between the layout managers you are using. Try getting rid f the one used by the IDE and creating the layout yourself.
