repainting issue

I have an applet that pops out a dialogbox. now how can i repaint tha applet when this dialog box is removed. I have so far passed a reference of the applet to the dialogbox and tried to repaint (via {applet}.repaint() ) and then use the update(g) method to paintComponents(g) but it is not working...

even tried repaint(tm) but failed.

Help much appreciated

heyhey_

applet is supposed to repaint itself - unless you block the event thread. do you perform any long task immediatelly after closing the dialog box (in the same thread) ?

yes...there is a long task after i close the dialog box...should i start the long task in a separate thread perhaps??

absolutely

well that's something that is very difficult for me to implement. This is the program flow:

methodXX()
{
[#1 perform some tasks, declare method variables]

if(error==true)
{
popUpDialogbox()
}
[#2 continue task, involves setting and accessing method variables declared above]
}

so now if i include portion #2 in a thread, i can't possibly set any of the values in #1 right? since the run() method of the Runnable class is void, i can't return any value to the method either. Only way is to use static variables??

thanks a bomb for any advice!!

but how about passing values from the thread back to the method?

just pass the result handler to the Task Thread

class TaskHandler extnds Thread
{
public ResultHandler resultHandler;
public int val1;
public String val2;

public void run()
{
// task 2
resultHandler.taskCompleted(result);
}
}

actually...i took an easier route....got the Sun Java Plugin and guess what...no more repainting problems!!!

cheers
thx for the help anyways
