java.lang.Object
org.gnu.glib.Timer
public final class Timer
extends java.lang.Object
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.

public Timer(int interval, Fireable target)
Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.
Create a new Timer object.
- Parameters:
interval
- the time period betweenfire
method executions, in thousandths of a second.target
- the object whose fire() method gets called after the specified time period elapses.
protected final void finalize() throws Throwable
Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.
Do not call this method; it's only purpose is to ensure that the timer is stopped before it is GC'd.
public final int getInterval()
Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.
Returns the interval associated with this Timer.
- Returns:
- the time period between
fire
method executions, in thousandths of a second.
public final boolean isRunning()
Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.
Returns whether this timer is running.
- Returns:
- true if this timer is currently running.
public final void setInterval(int interval)
Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.
Set the interval associated with this Timer.
- Parameters:
interval
- the time period betweenfire
method executions, in thousandths of a second.
public final void start()
Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.
Start this timer object; that is, begin executing its fire method at its specified interval.
public final void stop()
Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.
Stop this timer object; that is, stop executing its fire method at its specified interval. This method does not need to be called if thefire
method returnedfalse
