Question on asyncexec and updating UI Elements [message #516422]

I am trying to update a progressbar during a loop of processing.

new Thread()
{
public void run()
{
//some processing code here in a loop
progval++; //this is actually in the loop

try { Thread.sleep(100); } catch {}
if (display.isDisposed()) return;
display.getDefault().asyncExec(new Runnable() {
public void run()
{
progressBar.setSelection(progval);
}
});
}
}.start();

The problem is that progval, inside the Runnable, isn't recognized. How
do I get a value that is outside of the Runnable to be recognized and
usable inside? Is there a way to pass a value into it?

FIrst of all why are you not using Jobs API...

Secound...

The question is too generic...
there can be many answers....
1.make progval class level variable..
2.Create a class which impeiments runnable and create a constructor which gets the "progVal".

etc
