Constructor & Destructor Documentation

HistogramWidget()

Digikam::HistogramWidget::HistogramWidget	(	int	w,
		int	h,
		QWidget *const	parent = nullptr,
		bool	selectMode = true,
		bool	showProgress = true,
		bool	statisticsVisible = false )

Needed to use updateData() methods after to create valid instance.
