I've wrote an applet that renders some vector data. Applet's content pane has a JPanel
child as the canvas. Before the first rendering and (paint()-ing) this JPanel needs to
know its' own size to properly caclulate the size of object to be drawn. JApplet has a
BorderLayout, so everithing gets the size automatically.
First access of the applet is working fine. After a stop() and destroy() event (but
without closing the browser) and hitting again the applet's page the applet crashes because
of JPanel.getWidth() and getHeight() returns 0.
( I'm doing everything _after_ the init() and start() using invokeLater() ).

So I'm confused a bit, how and when the layouted components get their size.

After the first paint()? But then how can I calculate the correct sizes of object to be
 drawn? And why does work the applet after the first loading?

(Just a notice: none of my browsers follow the standard of applet's lifecycle events.
Displaying applet's page always causes init() and start(), and moving to another page
always causes stop() and destroy(). And I can't produce a combination of mouse clicks
 that causes a start() without init() or a stop() without destroy().)

Thanks for help,
regards,
