Hi, hope someone can help.

Is it possible to spawn a new window (say a JFrame) from an applet? I wish to create a new desktop separate from the browser window, if possible, as with menus and internal frames, an applet would get quite crowded in a browser.

Cheers! Email me if you like.
Chris.

It sure is. In JDK1.1 though you had to create a subclass of java.awt.Frame and then instanciate that. That may apply to SWING objects as well. So, create a MyJFrame which extends JFrame and then use the MyJFrame in your applet. I forgot why that little trick was necessary. May have been a bug or something ...

Mike,

THanks for your reply. I've tried this, but it doesn't seem to do the business. With a CommerApplet file extending JApplet and simply instantiating CommerGUI (which itself extends JFrame), I get the following error message in my IE4.72 Java console:

      java.lang.IllegalArgumentException: adding a window to a container
      at java/awt/Container.addImpl

Here is code from a clock applet I wrote which had the clock in it's own Window separate from the browser. It was my OtherTimeApplet which showed the user the time in other time zones. I wrote it for someone in Europe that needed it, since I thought it'd be an interesting little project to pursue. It looked fine on Netscape Navigator, but, unfortunately, I wasn't able to get it running on Microsoft Internet Explorer, but I suspect that it would work if I use Swing components.

      import OtherTimeFrame;

      class OtherTimeApplet
      {
      private static OtherTimeFrame frameClock;
      .
      .
      .
      public void start
      (
      )
      {
      frameClock = new OtherTimeFrame();
      frameClock.setResizable(false);
      frameClock.toFront();
      frameClock.show();
      }



      public void stop
      (
      )
      {
      frameClock.dispose();
      destroy();
      }
      .
      .
      .
      }
