Detailed Description

The vtkQtChartSeriesLayer class is the base class for chart layers that use the chart series model.

It stores the pointer to the chart series model and the list of options for the series. The series options are created using the createOptions method. Subclasses should overload this method to create the appropriate type of options object.

Member Function Documentation

virtual vtkQtChartSeriesOptions* vtkQtChartSeriesLayer::createOptions ( QObject * parent ) [protected, pure virtual]

Creates an options object for a series.

Note:: Subclasses should only create the options in this method. Use the setupOptions to set up connections.

Parameters:

parent The parent of the options object.

Returns:: A pointer to a new options object.

See also:: vtkQtChaerSeriesLayer::setupOptions(vtkQtChartSeriesOptions *)

Implemented in vtkQtBarChart, vtkQtLineChart, vtkQtStackedChart, and vtkQtStatisticalBoxChart.

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

Gets the chart series model.

Returns:: A pointer to the chart series model.

Definition at line 75 of file vtkQtChartSeriesLayer.h.

{return this->Model;}

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 vtkQtBarChart, vtkQtLineChart, 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 vtkQtBarChart, vtkQtLineChart, 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 vtkQtBarChart, vtkQtLineChart, vtkQtStackedChart, and vtkQtStatisticalBoxChart.

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 vtkQtBarChart, vtkQtLineChart, 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 vtkQtBarChart, vtkQtLineChart, vtkQtStackedChart, and vtkQtStatisticalBoxChart.

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.

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.

void vtkQtChartSeriesLayer::modelSeriesVisibilityChanged	(	int	series,
		bool	visible
	)		`[signal]`

Emitted when the visibility for a series has changed.

Parameters:

series	The index of the series.
visible	True if the series is visible.

void vtkQtChartSeriesLayer::resetSeriesOptions ( ) [slot]

Resets the series options for the model.

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:
