Thread Implementation

Posted by Tushar on June 22, 2000 at 8:40 PM

Hi ,
I hope you will answer the same in time..
I am facing a problem for implementing a thread for my process. Rather I don�t know where to implement the same in my whole code.

Could you provide some sample code/ working application which I can use as a template.
My application is something like this.

My main class extends JFrame
In it I am having a tree panel on left.
On click of any tree node, I need to process some data which takes several seconds.
For that time, I want to display a dialog box/progressbox on top of my current frame.

public class InfoCenter extends JFrame implements TreeSelectionListener, Runnable{

public void valueChanged( TreeSelectionEvent e ) {

here I need to popup progressbar and make a call to method that will generate the data for me.

private getStatusForPrograms(){
///this is that time consuming process.

}//end class InfoCenter.

Now if I want to start a thread or thread(s) possibly one for progressbar and another for the getStatusForPrograms (), how to do so?
From where should I call the getStatusForPrograms() and how to detect the completion of the getStatusForPrograms() so that I can hide the Dialog box.

So any inputs from you will be greatly helpful
Thanks and Regards
