Class QBasicTimer

extends QtJambiObject
implements java.lang.Cloneable

The `QBasicTimer` class provides timer events for objects. This is a fast, lightweight, and low-level class used by Qt internally. We recommend using the higher-level `QTimer` class rather than this class if you want to use timers in your applications.

To use this class, create a `QBasicTimer`, and call its `start()` function with a timeout interval and with a pointer to a `QObject` subclass. When the timer times out it will send a timer event to the `QObject` subclass. The timer can be stopped at any time using `stop()`. `isActive()` returns true for a timer that is running; i.e. it has been started, has not reached the timeout time, and has not been stopped. The timer's ID can be retrieved using `timerId()`.

The Wiggly example uses `QBasicTimer` to repaint a widget at regular intervals.

Constructor Detail

### QBasicTimer

    public QBasicTimer()

  Contructs a basic timer.

See also:
  `start()`.

Method Detail

### isActive

    public final boolean isActive()

  Returns true if the timer is running, has not yet timed out, and has not been stopped; otherwise returns false.

See also:
  `start()`, and `stop()`.

### start

    public final void start(int msec,
                            QObject obj)

  Starts (or restarts) the timer with a `msec` milliseconds timeout.

  The given `object` will receive timer events.

See also:
  `stop()`, `isActive()`, and `QObject::timerEvent()`.

### stop

    public final void stop()

  Stops the timer.

See also:
  `start()`, and `isActive()`.

### timerId

    public final int timerId()

  Returns the timer's ID.

See also:
  `QTimerEvent::timerId()`.

### clone

    public QBasicTimer clone()

  This method is reimplemented for internal reasons

  Overrides:
    `clone` in class `java.lang.Object`
