Detailed Description

This widget that consists of a QTreeView and a GraphicsView.

This is the easy to use, complete gantt chart widget. It consists of a QTreeView on the left and a KDGantt::GraphicsView on the right separated by a QSplitter. The two views share the same model.

void View::print	(	QPrinter *	printer,
		bool	drawRowLabels = true,
		bool	drawColumnLabels = true
	)

Print the Gantt chart using printer. If drawRowLabels is true (the default), each row will have it's label printed on the left side. If drawColumnLabels is true (the default), each column will have it's label printed at the top side.

This version of print() will print multiple pages.

void View::print	(	QPrinter *	printer,
		qreal	start,
		qreal	end,
		bool	drawRowLabels = true,
		bool	drawColumnLabels = true
	)

Print part of the Gantt chart from start to end using printer. If drawRowLabels is true (the default), each row will have it's label printed on the left side. If drawColumnLabels is true (the default), each column will have it's label printed at the top side.

This version of print() will print multiple pages.

To print a certain range of a chart with a DateTimeGrid, use qreal DateTimeGrid::mapFromDateTime( const QDateTime& dt) const to figure out the values for start and end.

void View::print	(	QPainter *	painter,
		const QRectF &	target = QRectF(),

		bool	drawColumnLabels = true
	)

Render the GanttView inside the rectangle target using the painter painter. If drawRowLabels is true (the default), each row will have it's label printed on the left side. If drawColumnLabels is true (the default), each column will have it's label printed at the top side.
