Title: suspend the awt thread

Yes, create the dialog and start the progress bar in the action peformed and then update it with calls to SwingUtilities.invokeLater in your MyRunnable class. Make sure you close the dialog in a finally block.   public void actionPerformed(ActionEvent ae) {     startProgressDialog();     Runnable runnable = new Runnable() {         public void run() {             try {                 // do some long operation and update progress dialog in the Swing thread when appropriate             } finally {                 closeProgressDialog(); // remember to do this in the swing thread         }     }     new Thread(runnable).start(); }   Hope this helps.

Now the progressbar is started in the MyRunnable() class. Are you saying that I should start it within the actionPerformed() method? -----Original Message----- From: Sachin Hejip [mailto:[EMAIL PROTECTED] Sent: woensdag 11 juni 2003 8:45 To: Deblauwe, Wim; [EMAIL PROTECTED] Subject: Re: suspend the awt thread Sorry - sent it before completing my sentence - I meant to say a) seems the best way . :-) ----- Original Message ----- From: Sachin Hejip To: Deblauwe, Wim ; [EMAIL PROTECTED] Sent: Wednesday, June 11, 2003 12:14 PM 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 ----- Original Message ----- From: Deblauwe, Wim To: '[EMAIL PROTECTED]' Sent: Wednesday, June 11, 2003 11:40 AM 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 ------------- Ing.
