<B>Deprecated.</B> <I>This class is part of the java-gnome 2.x family of libraries,
which, due to their inefficiency and complexity, are no longer
being maintained and have been abandoned by the java-gnome
project. This class may have an equivalent in java-gnome 4.0,
see <code>org.gnome.glib.Timer</code>.
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.</I>
<P>
<DL>
<DT><PRE>public final class <B>Timer</B><DT>extends java.lang.Object</DL>
</PRE>
<P>
Timer: an object that executes a <code>Fireable</code> target object's
<code>fire</code> method at a specified interval.
<p>
For example, here's how an application clock might be implemented, where the
application passes in an <CODE>org.gnu.gtk.Label</CODE> object as its pane:
<pre>
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();
</pre>
<p>
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.
