You should be aware that there is a considerably different API
in the new library: the architecture is completely different
and most notably internals are no longer exposed to public view.
public final class Timer
Timer: an object that executes a Fireable
target object's
fire
method at a specified interval.
For example, here's how an application clock might be implemented, where the
application passes in an org.gnu.gtk.Label
object as its pane:
private final Label clockPane = (Label) glade.getWidget("clockLabel"); private Timer clock = new Timer(1000, // one second new Fireable() { public boolean fire() { String dateStr = DateFormat.getDateInstance() .format(new Date()); clockPane.setText(dateStr); return true; // continue firing } }); clock.start();
Note: a Timer generates events on the application's GUI event queue. It therefore is not accurate for short time periods. It also should only be used to directly fire short/fast methods. Longer methods need to be executed in a separate thread.
