I made in Timer. Here the code:

int delay = 30000;
Timer timer = new Timer();
timer.schedule(new TimerTask() {
            public void run() {
                myDialog.toFront();
                myDialog.repaint();}
                }, delay);

but my dialog did not appear on the front of all windows.

Your code is running on the wrong thread. See
SwingUtilities.invokeLater.

Probably not necessary. repaint() certainly not and toFront() is a
method of Window and probably doesn't need to be called on the EDT.

Why would it not need to be called on the EDT?

There isn't anything in the Javadocs to indicate that Window is thread
safe.

Window is an AWT component. No requirement to use the EDT on AWT
components that I know of.

I'm not really sure the toFront() and toBack() is the way to get this to
work. toFront() only puts the window in front of other windows in the
same VM. The setAlwaysOnTop() works fine on my XP box though.
