virtual void vtkQtStackedChart::setChartArea ( vtkQtChartArea * area ) [virtual]

Sets the chart area for the chart layer.

If the model is set before the chart layer is added to a chart area, series options will not be available. Setting the chart area will create the series options for the model in this case. Subclasses can extend this method to handle the new options.

Parameters:

area

The new chart area.

Reimplemented from vtkQtChartSeriesLayer.

virtual void vtkQtStackedChart::setModel ( vtkQtChartSeriesModel * model ) [virtual]

Sets the chart series model.

Parameters:

model

The new chart series model.

Reimplemented from vtkQtChartSeriesLayer.

vtkQtStackedChartOptions* vtkQtStackedChart::getOptions ( ) const [inline]

Gets the stacked chart drawing options.

Returns:: A pointer to the stacked chart drawing options.

Definition at line 58 of file vtkQtStackedChart.h.

void vtkQtStackedChart::setOptions ( const vtkQtStackedChartOptions & options )

Sets the stacked chart drawing options.

This method sets all the options at once, which can prevent unnecessary view updates.

Parameters:

options

The new stacked chart drawing options.

virtual QPixmap vtkQtStackedChart::getSeriesIcon ( int series ) const [virtual]

Gets the stacked chart drawing options.

Returns:: A pointer to the stacked chart drawing options.

Reimplemented from vtkQtChartSeriesLayer.

virtual void vtkQtStackedChart::getLayerDomain ( vtkQtChartLayerDomain & domain ) const [virtual]

Notifies the chart layer that a resize interaction has finished.

The chart quad tree is not updated while the chart is in an interactive state. It is updated in this method if needed.

Reimplemented from vtkQtChartLayer.

virtual void vtkQtStackedChart::layoutChart ( const QRectF & area ) [virtual]

Notifies the chart layer that a resize interaction has finished.

The chart quad tree is not updated while the chart is in an interactive state. It is updated in this method if needed.

Implements vtkQtChartLayer.

virtual bool vtkQtStackedChart::getHelpText	(	const QPointF &	point,
		QString &	text
	)			`[virtual]`

Notifies the chart layer that a resize interaction has finished.

The chart quad tree is not updated while the chart is in an interactive state. It is updated in this method if needed.

Reimplemented from vtkQtChartLayer.

virtual void vtkQtStackedChart::finishInteractiveResize ( ) [virtual]

Notifies the chart layer that a resize interaction has finished.

The chart quad tree is not updated while the chart is in an interactive state. It is updated in this method if needed.

Reimplemented from vtkQtChartLayer.

virtual void vtkQtStackedChart::getSeriesAt	(	const QPointF &	point,
		vtkQtChartSeriesSelection &	selection
	)			const `[virtual]`

Gets the list of series at a given position.

Parameters:

	point	The position in scene coordinates.
	selection	Used to return the list of series.

Reimplemented from vtkQtChartSeriesLayer.

virtual void vtkQtStackedChart::getPointsAt	(	const QPointF &	point,
		vtkQtChartSeriesSelection &	selection
	)			const `[virtual]`

Gets the list of points at a given position.

Parameters:

	point	The position in scene coordinates.
	selection	Used to return the list of points.

Reimplemented from vtkQtChartSeriesLayer.

virtual void vtkQtStackedChart::getSeriesIn	(	const QRectF &	area,
		vtkQtChartSeriesSelection &	selection
	)			const `[virtual]`

Gets the list of series in a given area.

Parameters:

	area	The rectangle in scene coordinates.
	selection	Used to return the list of series.

Reimplemented from vtkQtChartSeriesLayer.

virtual void vtkQtStackedChart::getPointsIn	(	const QRectF &	area,
		vtkQtChartSeriesSelection &	selection
	)			const `[virtual]`

Gets the list of points in a given area.

Parameters:

	area	The rectangle in scene coordinates.
	selection	Used to return the list of points.

Reimplemented from vtkQtChartSeriesLayer.

virtual QRectF vtkQtStackedChart::boundingRect ( ) const [virtual]

virtual void vtkQtStackedChart::paint	(	QPainter *	painter,
		const QStyleOptionGraphicsItem *	option,
		QWidget *	widget = `0`
	)			`[virtual]`

void vtkQtStackedChart::reset ( ) [slot]

Refreshes the stacked chart data from the model.

The currently displayed data is cleaned up. If a model is set, it is used to populate the stacked chart.

virtual void vtkQtStackedChart::handleOptionsChanged	(	vtkQtChartSeriesOptions *	,
		int	type,
		const QVariant &	newvalue,
		const QVariant &	oldvalue
	)			`[protected, virtual, slot]`

Called when any of the series options are changed.

Default implementation fires the modelSeriesChanged() signal.

Parameters:

	options	The options that fired the dataChanged() signal.
	type	Type of the option that was changed.
	newValue	The new value for the option.
	oldValue	The previous value for the option, if any.

Reimplemented from vtkQtChartSeriesLayer.
