void GraphicsScene::print	(	QPrinter *	printer,
		bool	drawRowLabels = `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 GraphicsScene::print	(	QPrinter *	printer,
		qreal	start,
		qreal	end,

	)

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.
