Detailed Description

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. Note that this timer is a repeating timer that will send subsequent timer events unless the stop() function is called.

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 & Destructor Documentation

QtCore.QBasicTimer.QBasicTimer ( System.Type  dummy)
protected
QtCore.QBasicTimer.QBasicTimer ( )

Contructs a basic timer.

See also start().

QtCore.QBasicTimer.QBasicTimer ( QBasicTimer  copy)

Member Function Documentation

virtual void QtCore.QBasicTimer.CreateProxy ( )
virtual
new void QtCore.QBasicTimer.Dispose ( )
new void QtCore.QBasicTimer.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().

new void QtCore.QBasicTimer.Stop ( )

Stops the timer.

See also start() and isActive().
