Member Function Documentation

virtual void vtkQtChartSeriesLayer::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 vtkQtChartLayer.

Reimplemented in vtkQtLineChart, vtkQtBarChart, vtkQtStackedChart, and vtkQtStatisticalBoxChart.

vtkQtChartSeriesModel* vtkQtChartSeriesLayer::getModel ( ) const [inline]

Gets the chart series model.

Returns:: A pointer to the chart series model.

Definition at line 74 of file vtkQtChartSeriesLayer.h.

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

Sets the chart series model.

Parameters:

model The new chart series model.

Reimplemented in vtkQtLineChart, vtkQtBarChart, vtkQtStackedChart, and vtkQtStatisticalBoxChart.

vtkQtChartSeriesOptionsModel* vtkQtChartSeriesLayer::getOptionsModel ( ) const [inline]

Gets the chart series options model.

Returns:: A pointer to the current chart series options model.

Definition at line 85 of file vtkQtChartSeriesLayer.h.

virtual void vtkQtChartSeriesLayer::setOptionsModel ( vtkQtChartSeriesOptionsModel * model ) [virtual]

Sets the chart series options model.

Parameters:

model The new chart series options model.

vtkQtChartSeriesOptions* vtkQtChartSeriesLayer::getSeriesOptions ( int series ) const

Gets the drawing options for the given series.

Parameters:

series The index of the series.

Returns:: A pointer to the drawing options for the given series.

int vtkQtChartSeriesLayer::getSeriesOptionsIndex ( vtkQtChartSeriesOptions * options ) const

Gets the index for the given series options.

Parameters:

options The series options object.

Returns:: The index for the given series options.

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

Gets the icon for a given series.

The icon is used by the chart legend.

Parameters:

series The index of the series.

Returns:: A pixmap representation of the series.

Reimplemented in vtkQtLineChart, vtkQtBarChart, vtkQtStackedChart, and vtkQtStatisticalBoxChart.

vtkQtChartSeriesSelectionModel* vtkQtChartSeriesLayer::getSelectionModel ( ) const

Gets the chart series selection model.

Returns:: A pointer to the chart series selection model.

virtual void vtkQtChartSeriesLayer::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 in vtkQtLineChart, vtkQtBarChart, vtkQtStackedChart, and vtkQtStatisticalBoxChart.

virtual void vtkQtChartSeriesLayer::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 in vtkQtLineChart, vtkQtBarChart, vtkQtStackedChart, and vtkQtStatisticalBoxChart.

virtual void vtkQtChartSeriesLayer::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 in vtkQtLineChart, vtkQtBarChart, vtkQtStackedChart, and vtkQtStatisticalBoxChart.

virtual void vtkQtChartSeriesLayer::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 in vtkQtLineChart, vtkQtBarChart, vtkQtStackedChart, and vtkQtStatisticalBoxChart.

void vtkQtChartSeriesLayer::setXOffset ( float offset ) [slot]

Sets the contents x-axis offset.

Parameters:

offset The new x-axis offset.

void vtkQtChartSeriesLayer::setYOffset ( float offset ) [slot]

Sets the contents y-axis offset.

Parameters:

offset The new y-axis offset.

void vtkQtChartSeriesLayer::modelChanged	(	vtkQtChartSeriesModel *	previous,
		vtkQtChartSeriesModel *	current
	)		`[signal]`

Emitted when the series model is changed.

Parameters:

previous	The previous series model.
current	The current series model.

void vtkQtChartSeriesLayer::modelSeriesChanged	(	int	first,
		int	last
	)		`[signal]`

Emitted when the name or icon changes for a set of series.

Parameters:

first	The first series index of the range.
last	The last series index of the range.

virtual void vtkQtChartSeriesLayer::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 in vtkQtBarChart, vtkQtLineChart, vtkQtStackedChart, and vtkQtStatisticalBoxChart.

virtual void vtkQtChartSeriesLayer::setupOptions ( vtkQtChartSeriesOptions * options ) [protected, virtual]

Sets up the default values for the series options object.

The style manager should be used to help set up the series options. Subclass must call this method every time a new series options is set up.

Parameters:

options The newly created series options.

Reimplemented in vtkQtStatisticalBoxChart.

virtual void vtkQtChartSeriesLayer::cleanupOptions ( vtkQtChartSeriesOptions * options ) [protected, virtual]

Cleans up the options by deallocating the style reservation for the option.

Subclass must call this method before a series options object is cleaned up.
