Member Function Documentation

virtual void vtkQtLineChart::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 vtkQtLineChart::setModel ( vtkQtChartSeriesModel model  )  [virtual]

Sets the chart series model.

Parameters:
model The new chart series model.

Reimplemented from vtkQtChartSeriesLayer.

vtkQtLineChartOptions* vtkQtLineChart::getOptions (  )  const [inline]

Gets the line chart drawing options.

Returns:
A pointer to the line chart drawing options.

Definition at line 61 of file vtkQtLineChart.h.

void vtkQtLineChart::setOptions ( const vtkQtLineChartOptions options  ) 

Sets the line chart drawing options.

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

Parameters:
options The new line chart drawing options.

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

Gets the line chart drawing options.

Returns:
A pointer to the line chart drawing options.

Reimplemented from vtkQtChartSeriesLayer.

virtual void vtkQtLineChart::getLayerDomain ( vtkQtChartLayerDomain domain  )  const [virtual]

Notifies the chart layer that a resize interaction has finished.

The chart search trees are not updated while the chart is in an interactive state. It is updated in this method if needed.

Reimplemented from vtkQtChartLayer.

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

Notifies the chart layer that a resize interaction has finished.

The chart search trees are not updated while the chart is in an interactive state. It is updated in this method if needed.

Implements vtkQtChartLayer.

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

Notifies the chart layer that a resize interaction has finished.

The chart search trees are not updated while the chart is in an interactive state. It is updated in this method if needed.

Reimplemented from vtkQtChartLayer.

virtual void vtkQtLineChart::finishInteractiveResize (  )  [virtual]

Notifies the chart layer that a resize interaction has finished.

The chart search trees are not updated while the chart is in an interactive state. It is updated in this method if needed.

Reimplemented from vtkQtChartLayer.

virtual void vtkQtLineChart::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 vtkQtLineChart::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 vtkQtLineChart::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 vtkQtLineChart::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 vtkQtLineChart::boundingRect (  )  const [virtual]

virtual void vtkQtLineChart::paint ( QPainter *  painter,
const QStyleOptionGraphicsItem *  option,
QWidget *  widget 
) [virtual]

void vtkQtLineChart::reset (  )  [slot]

Refreshes the line chart data from the model.

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

virtual void vtkQtLineChart::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.

void vtkQtLineChart::handleLayoutNeeded (  )  [protected, slot]

Called when this layer fires the layoutNeeded() signal is fired.
