| virtual QRectF vtkQtStackedChart::boundingRect | ( | ) | const [virtual] |
| virtual vtkQtChartSeriesOptions* vtkQtStackedChart::createOptions | ( | QObject * | parent ) | [protected, virtual] |
Creates a new stacked chart series options object.
| parent | The parent object. |
Implements vtkQtChartSeriesLayer.
| 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 bool vtkQtStackedChart::getHelpText | ( | const QPointF & | point, |
| QString & | text | ||
| ) | [virtual] |
Gets the help text for the given location.
When the chart receives a help event, the layers are searched, in order, for help text at the help event location. If a layer has an item at the location, it should return true.
| point | The help location in scene coordinates. |
| text | Used to return the help text. |
Reimplemented from vtkQtChartLayer.
| virtual void vtkQtStackedChart::getLayerDomain | ( | vtkQtChartLayerDomain & | domain ) | const [virtual] |
Gets the chart layer's domain.
The layer should use the mergeDomain method of the domain parameter to add its domains. The domains from all of the chart layers will be combined using the domain object.
| domain | Used to return the chart layer's domain. |
Reimplemented from vtkQtChartLayer.
| vtkQtStackedChartOptions* vtkQtStackedChart::getOptions | ( | ) | const [inline] |
Gets the stacked chart drawing options.

{return this->Options;}
| virtual void vtkQtStackedChart::getPointsAt | ( | const QPointF & | point, |
| vtkQtChartSeriesSelection & | selection | ||
| ) | const [virtual] |
Gets the list of points at a given position.
| point | The position in scene coordinates. |
| selection | Used to return the list of points. |
Reimplemented from vtkQtChartSeriesLayer.
| virtual void vtkQtStackedChart::getPointsIn | ( | const QRectF & | area, |
| vtkQtChartSeriesSelection & | selection | ||
| ) | const [virtual] |
Gets the list of points in a given area.
| area | The rectangle in scene coordinates. |
| selection | Used to return the list of points. |
Reimplemented from vtkQtChartSeriesLayer.
| virtual void vtkQtStackedChart::getSeriesAt | ( | const QPointF & | point, |
| vtkQtChartSeriesSelection & | selection | ||
| ) | const [virtual] |
Gets the list of series at a given position.
| point | The position in scene coordinates. |
| selection | Used to return the list of series. |
Reimplemented from vtkQtChartSeriesLayer.
| virtual QPixmap vtkQtStackedChart::getSeriesIcon | ( | int | series ) | const [virtual] |
Gets the icon for a given series.
The icon is used by the chart legend.
| series | The index of the series. |
Reimplemented from vtkQtChartSeriesLayer.
| virtual void vtkQtStackedChart::getSeriesIn | ( | const QRectF & | area, |
| vtkQtChartSeriesSelection & | selection | ||
| ) | const [virtual] |
Gets the list of series in a given area.
| area | The rectangle in scene coordinates. |
| selection | Used to return the list of series. |
Reimplemented from vtkQtChartSeriesLayer.
| vtkQtStackedChartSeriesOptions* vtkQtStackedChart::getStackedSeriesOptions | ( | int | series ) | const |
Gets the stacked chart series options.
| series | The series index. |
| virtual void vtkQtStackedChart::layoutChart | ( | const QRectF & | area ) | [virtual] |
Used to layout the chart layer.
Use the AxisDomain from the relevant axes to determine if the chart data can be displayed. The domain priority for the axes can override a layer's desired domain.
| area | The area the chart should occupy. |
Implements vtkQtChartLayer.
| 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::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.
| area | The new chart area. |
Reimplemented from vtkQtChartSeriesLayer.
| virtual void vtkQtStackedChart::setModel | ( | vtkQtChartSeriesModel * | model ) | [virtual] |
Sets the chart series model.
| model | The new chart series model. |
Reimplemented from vtkQtChartSeriesLayer.
| 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.
| options | The new stacked chart drawing options. |
| virtual void vtkQtStackedChart::setupOptions | ( | vtkQtChartSeriesOptions * | options ) | [protected, virtual] |
Sets up the series options defaults.
| options | The new series options object. |
Implements vtkQtChartSeriesLayer.
