IsTypeOf()

static vtkTypeBool vtkChartPie::IsTypeOf ( const char *  type )

static

IsA()

virtual vtkTypeBool vtkChartPie::IsA ( const char *  name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkChart.

SafeDownCast()

static vtkChartPie * vtkChartPie::SafeDownCast ( vtkObjectBase *  o )

static

NewInstanceInternal()

virtual vtkObjectBase * vtkChartPie::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkChart.

NewInstance()

vtkChartPie * vtkChartPie::NewInstance

(

)

const

PrintSelf()

void vtkChartPie::PrintSelf ( ostream &  os, vtkIndent  indent  )

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkChart.

New()

static vtkChartPie * vtkChartPie::New ( )

static

Creates a 2D Chart object.

Update()

void vtkChartPie::Update ( )

overridevirtual

Perform any updates to the item that may be necessary before rendering.

Reimplemented from vtkAbstractContextItem.

Paint()

bool vtkChartPie::Paint ( vtkContext2D *  painter )

overridevirtual

Paint event for the chart, called whenever the chart needs to be drawn.

Implements vtkChart.

overridevirtual

Add a plot to the chart.

Reimplemented from vtkChart.

SetPlot()

virtual void vtkChartPie::SetPlot ( vtkPlotPie *  plot )

virtual

Set plot to use for the chart.

Since this type of chart can only contain one plot, this will replace the previous plot.

GetPlot()

vtkPlot * vtkChartPie::GetPlot ( vtkIdType  index )

overridevirtual

Get the plot at the specified index, returns null if the index is invalid.

Reimplemented from vtkChart.

GetNumberOfPlots()

Reimplemented from vtkChart.

SetScene()

void vtkChartPie::SetScene ( vtkContextScene *  scene )

overridevirtual

Set the vtkContextScene for the item, always set for an item in a scene.

Reimplemented from vtkAbstractContextItem.

Hit()

bool vtkChartPie::Hit ( const vtkContextMouseEvent &  mouse )

overridevirtual
