I can give you some skeleton for your application:
1/ put senFile in a Thread subclass
2/ create another Thread subclass like this:
class MonitorThread extends Thread {
public void run() {
EventQueue.invokeLater(new Runnable() {
// init on the EDT
progress.setValue(0);
I make it... .. it works quite well, but update progress I am running in
timer because
Thread.sleep(100) resulted in a hung IE browser (applet)
I am setting delay on 1000 ms, but update but it does not perform the
equivalent time at 1 second and once every 5
how repaired it? Can anything changing priorities of threads?
