I'm not working with applets. In an application You can do the following
Button1ActionPerformed (ActionEvent evt) {
Runnable afterRunner = new Runnable() {
public void run() {
// do button operation
// SHORT PROCESSING else GUI is blocked
}
};
Runnable runner = new Runnable() {
public void run() {
try {
// HEAVY BACKGROUND PROCESSING
// Put the button operation runnable on the
event queue
SwingUtilities.invokerLater(afterRunner);
} catch(Exception e){
System.out.println(e);
}
}
//RETURN FASTLY CONTROL
}

Subject: RE: Threads inside actionPerformed event
Hi again,
I'm using JDK 1.3, and the problem is that the "actionPerformed" event
blocks the GUI and I can't do anything else.
I've tried with invokeLater(), and also invokeLater() within another created
thread inside the "actionPerformed" event, but the GUI is freezed until the
event is consumed.
Any solution??
Thanks
