virtual const char* vtkChartPie::GetClassName

(

)

[virtual]

Reimplemented from vtkChart.

static int vtkChartPie::IsTypeOf

(

const char *

name

)

[static]

Return 1 if this class type 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.

virtual int 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.

static vtkChartPie* vtkChartPie::SafeDownCast

(

vtkObject *

o

)

[static]

Reimplemented from vtkChart.

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

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.

static vtkChartPie* vtkChartPie::New

(

)

[static]

Creates a 2D Chart object.

Reimplemented from vtkObject.

virtual void vtkChartPie::Update

(

)

[virtual]

Perform any updates to the item that may be necessary before rendering. The scene should take care of calling this on all items before their Paint function is invoked.

Reimplemented from vtkAbstractContextItem.

virtual bool vtkChartPie::Paint

(

vtkContext2D *

painter

)

[virtual]

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

Implements vtkChart.

virtual vtkPlot* vtkChartPie::AddPlot

(

int

type

)

[virtual]

Add a plot to the chart.

Reimplemented from vtkChart.

virtual vtkIdType vtkChartPie::AddPlot

(

vtkPlot *

plot

)

[inline, virtual]

Add a plot to the chart. Return the index of the plot, -1 if it failed.

Reimplemented from vtkChart.

Definition at line 59 of file vtkChartPie.h.

virtual vtkPlot* vtkChartPie::GetPlot

(

vtkIdType

index

)

[virtual]

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

Reimplemented from vtkChart.

virtual vtkIdType vtkChartPie::GetNumberOfPlots

(

)

[virtual]

Get the number of plots the chart contains.

Reimplemented from vtkChart.

virtual void vtkChartPie::SetShowLegend

(

bool

visible

)

[virtual]

Set whether the chart should draw a legend.

Reimplemented from vtkChart.

virtual vtkChartLegend* vtkChartPie::GetLegend

(

)

[virtual]

Get the legend for the chart, if available. Can return NULL if there is no legend.

Reimplemented from vtkChart.

virtual void vtkChartPie::SetScene

(

vtkContextScene *

scene

)

[virtual]

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

Reimplemented from vtkAbstractContextItem.

virtual bool vtkChartPie::Hit

(

const vtkContextMouseEvent &

mouse

)

[virtual]

Return true if the supplied x, y coordinate is inside the item.

Reimplemented from vtkAbstractContextItem.

virtual bool vtkChartPie::MouseEnterEvent

(

const vtkContextMouseEvent &

mouse

)

[virtual]

Mouse enter event.

Reimplemented from vtkAbstractContextItem.

virtual bool vtkChartPie::MouseMoveEvent

(

const vtkContextMouseEvent &

mouse

)

[virtual]

Mouse move event.

Reimplemented from vtkAbstractContextItem.

virtual bool vtkChartPie::MouseLeaveEvent

(

const vtkContextMouseEvent &

mouse

)

[virtual]

Mouse leave event.

Reimplemented from vtkAbstractContextItem.

virtual bool vtkChartPie::MouseButtonPressEvent

(

const vtkContextMouseEvent &

mouse

)

[virtual]

Mouse button down event

Reimplemented from vtkAbstractContextItem.

virtual bool vtkChartPie::MouseButtonReleaseEvent

(

const vtkContextMouseEvent &

mouse

)

[virtual]

Mouse button release event.

Reimplemented from vtkAbstractContextItem.

virtual bool vtkChartPie::MouseWheelEvent	(	const vtkContextMouseEvent &	mouse,
		int	delta
	)			[virtual]

Mouse wheel event, positive delta indicates forward movement of the wheel.

Reimplemented from vtkAbstractContextItem.

void vtkChartPie::RecalculatePlotTransforms

(

)

[protected]

Recalculate the necessary transforms.
