Subject: Re: suspend the awt thread
Hey,
From what I understood what you wish to achieve is that the
UI should continue to repaint but the user should not be able to interact with
it while you complete your task?
You can -
a) Show a modal dialog that says "Please Wait" or shows a
progress bar preferably with a cancel button - this dialog disappears on the
completion of your task. (I think this is the
b) Disable all input event dispatching until your operation
concludes by replacing the EventQueue with your own.
c) A harder way to achieve this is to have the glass pane
take focus, block mouse events and disable all menus.
Does this help?
Regards
Sachin

Subject: suspend the awt thread
Hi,
I want to suspend the awt thread but still get painting
done. Is this possible?
assume this piece of code:
actionPerformed(ActionEvent e)
{
Runnable myRunnable = new MyRunnable();
Thread
workerThread = new Thread( myRunnable );
workerThread.start();
// Wait here for
workerThread to finish
// but still paint!
Oject o =
myRunnable.getObject();
// do something
with o
}
You are in the actionPerformed, so this gets executed on the
awt thread. The workerThread starts with some lengthy operation and we want
to wait in the actionPerformed for it to finish and then continue with our
work. How do I do it?
kind regards,
Wim
