Question

Bug in IE?

Asked by: tgrundvik

I have an HTML-page that lounches another HTML-page in its own window. This page again lounches a JavaApplet in a Frame.
When I close the window that lounched the JavaApplet, the Applet-frame does not close.
How can i make a script to ensure that the Applet is destoryed and the frame is closed?
(Netscape Navigator destroys the Applet)

Can we see that in action, please???

You may want to do
onUnload="document.myApplet.finish()"
where finish is a public method that cleans up, but I have never heard of this happening before

I hope YOU made the applet.

You probably extended the applet with Runnable, and will therefore also (probably) use Threads....

You should override the Thread-methods.

public void start()
public void run()
public void stop()

the stop part is where you need to add code (and even more additional code for NS!) like:

      Thread                  killThread;

      public class KillThread extends Thread
      {
            Applet parent;
          final int KILLTHREADINTERVAL = 5000; // 5 seconds
          public KillThread (Applet p)
            {
                  super("killThread");
                  parent = p;
            }

            public void run ()
            {
                  try
                  {
                        sleep(KILLTHREADINTERVAL);
                  }
                  catch (InterruptedException e) {}
                  parent.destroy();
            }
      }

      public void destroy()
      {
            if (thMusic != null)
            {
                  thMusic.stop();
                  thMusic = null;
            }
            
            if (killThread != null)
            {
                  killThread.stop();
                  killThread = null;
            }
    }



public void stop()
{
    if((MyThread!=null) && (MyThread.isAlive()))
    {
         thMusic.suspend();
    }
            
    if (killThread != null)
        System.out.println ("ERROR - killThread shouldn't exist");
    else
    {
         killThread = new KillThread(this);  
         killThread.start();  
    }
}


Which will in general check for when the stop method is called, and then creates a new thread which will keep it alive for some more time (for NS)...and if that one expires will THEN get rid of everything....

I hope that helped a bit...

regards,
CJ

public void destroy()
{
if (thMusic != null)
{
thMusic.stop();
thMusic = null;
}

if (killThread != null)
{
killThread.stop();
killThread = null;
}
    }





should be for you:

public void destroy()
{
if (MyThread != null)
{
MyThread.stop();
MyThread = null;
}

if (killThread != null)
{
killThread.stop();
killThread = null;
}
    }

Is onUnload triggered when the IE window is closing? I thougt it was only triggered when a new document was loaded.

You can see the problem at:

unsigned java and have it like this. Damn, I'm impressed!....
looks pretty neat, though it was not fullscreen...

 

by: mplungjanPosted on 2000-08-31 at 08:00:12ID: 4143660

It was for me - completely fullscreen NS 4.75 under NT4

Michel

 

by: mplungjanPosted on 2000-08-31 at 08:00:50ID: 4143664

tgrundvik: would you care to share the secret of the fullscreen?

Michel

 

by: CJ_SPosted on 2000-08-31 at 08:12:15ID: 4143793

Not for me 1600x1400, NT4 SP 6
NS 4.72

And I wonder why IE doesn't work...uhm...

and yes, I definitely would look to know the secret!

 

by: mplungjanPosted on 2000-08-31 at 08:48:06ID: 4144513

Oh so it is allowed to blow to 1600*1200 and not complain?

Michel

 

by: tgrundvikPosted on 2000-08-31 at 09:57:01ID: 4145580

You can create a window that is larger than the screen! But, if you try to drag the window, you will get the Warning: untrusted bla bla. And it is not fullscreen, it is scaled to 1024x800.

 

by: CJ_SPosted on 2000-08-31 at 10:47:14ID: 4145935

uhmm, still interesting....I tried a qwhile ago to use Java and DirectX and DirectX can go fullscreen. I know how ta do it in C++ so I might just try it in java. :/.....

I don't like to complain but the dragging of the window you created, tgrundvik, that....seems a bit weird...everywhere you click on the titlebar the applet / window will move it's upper left corner to the mouseposition. I don't think that is normal...or is it?
