HOW TO MAKE A TIMED TASK WITH TINYTASK UPDATE
TumbleItem applet uses a timer to update its display at regular intervals. Let's look at an example of using a timer to periodically update a component. SeeĬoncurrency in Swing for instructions about using the SwingWorker class and information on using Swing components in multi-threaded programs. If the task might take a while to execute, then consider using a SwingWorker instead of or in addition to the timer. This is an in-built windows command supported by XP, Vista and Windows 7. This means that the task can safely manipulate components, but it also means that the task should execute quickly. ‘Schedule tasks‘ is a GUI application using which we can schedule tasks, There is an equivalent utility which provides the same functionality but with the advantage that it can be used from windows command line. If that doesn’t do it, maybe the app has no GUI. If that does not do it, look for it in the set of tiny icons by the clock. Note that the Swing timer's task is performed in the event dispatch thread. Right click on the taskbar and select cascade windows. To start the timer, call its start method. If you want the timer to go off only once, you can invoke setRepeats(false) on the timer. When you create the timer, you also specify the number of milliseconds between timer firings.
HOW TO MAKE A TIMED TASK WITH TINYTASK CODE
The actionPerformed method in this listener should contain the code for whatever task you need to be performed. When you create the timer, you specify an action listener to be notified when the timer "goes off". However, you might use a general-purpose timer if you don't plan on touching the GUI from the timer, or need to perform lengthy processing.įor example, the tool tip manager uses Swing timers to determine when to show a tool tip and when to hide it.įor example, you might perform animation or update a component that displays progress toward a goal. In general, we recommend using Swing timers rather than general-purpose timers for GUI-related tasks because Swing timers all share the same, pre-existing timer thread and the GUI-related task automatically executes on the event-dispatch thread. Do not confuse Swing timers with the general-purpose timer facility in the java.util package. Click ok, once you select the desired schedule. Here we are making the schedule of daily midnight and my Windows automatically shut down at night. Make Schedule according to your choice so that your windows automatically shut down. ) fires one or more action events after a specified delay. In the New Windows make sure on the drop down menu of Begin the Task just choose On a Schedule.
