Constructor & Destructor Documentation

◆ CountDownWidget()

CountDownWidget::CountDownWidget	(	int	start,
		int	stop,
		unsigned	msec,
		WContainerWidget *	parent = `0`
	)

Create a new CountDownWidget.

The widget will count down from start to stop, decrementing the number every msec milliseconds.
