JFrame not showing up in JApplet until applet is resized

Question

I am creating a Java applet, and I am trying to add a JFrame to it. I am calling:

add(new MyJFrameSubclass());

But when I launch the application, my JFrame isn't shown until I resize the window.

Answer 1

JFrame and JApplet are both top-level containers. Instead of trying to have both containers present at once, put your content in a lightweight container such as JPanel; then add that JPanel to either a JFrame (for local use) or a JApplet (for the browser). This example shows the approach.

Answer 2

This may be too elementary of a suggestion, but sticking in a validate() or repaint() can sometimes solve problems that seem complicated.
