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 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 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 vtkQtBarChart, vtkQtLineChart, 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 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 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::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.

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.

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.
