suspend the awt thread
Title: 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

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?

Sachin

Yes,
a) is what I want to do. Now the progressbar is started in the MyRunnable()
class. Are you saying that I should start it within the actionPerformed()
method?
