Member Function Documentation

virtual bool vtkQtChartShape::contains

(

const QPointF &

point )

const [pure virtual]

Gets whether or not the shape contains the given point.

Parameters:

point

The position to evaluate.

Returns:

True if the shape contains the given point.

Implemented in vtkQtChartBar, and vtkQtChartQuad.

static int vtkQtChartShape::getBoundingBoxCode	(	const QPointF &	point,
		const QRectF &	bounds
	)		[static]

Gets the bounding box code for the given point and rectangle.

This method combines the x and y bounding box codes.

Parameters:

point	The position to evaluate.
bounds	The bounding box.

virtual void vtkQtChartShape::getBounds

(

QRectF &

bounds )

const [pure virtual]

Gets the bounding box for the shape.

Parameters:

bounds

Used to return the bounding box.

Implemented in vtkQtChartBar, and vtkQtChartQuad.

int vtkQtChartShape::getIndex

(

)

const [inline]

Gets the index in the series.

Returns:

The index in the series.

Definition at line 118 of file vtkQtChartShape.h.

{return this->Index;}

int vtkQtChartShape::getSeries

(

)

const [inline]

Gets the series number.

Returns:

The series number.

Definition at line 107 of file vtkQtChartShape.h.

{return this->Series;}

static int vtkQtChartShape::getXBoundingBoxCode	(	float	x,
		const QRectF &	bounds
	)		[static]

Gets the bounding box code for the given coordinate and rectangle.

Parameters:

x	The x position to evaluate.
bounds	The bounding box.

static int vtkQtChartShape::getYBoundingBoxCode	(	float	y,
		const QRectF &	bounds
	)		[static]

Gets the bounding box code for the given coordinate and rectangle.

Parameters:

y	The y position to evaluate.
bounds	The bounding box.

virtual bool vtkQtChartShape::intersects

(

const QRectF &

area )

const [pure virtual]

Gets whether or not the shape intersects the given area.

Parameters:

area	The area to evaluate.

Returns:

True if the shape intersects the given area.

Implemented in vtkQtChartBar, and vtkQtChartQuad.

vtkQtChartShape& vtkQtChartShape::operator=

(

const vtkQtChartShape &

other )

void vtkQtChartShape::setIndex

(

int

index )

[inline]

Sets the index in the series.

Parameters:

index

The new index in the series.

Definition at line 123 of file vtkQtChartShape.h.

{this->Index = index;}

virtual void vtkQtChartShape::setPolygon

(

const QPolygonF &

polygon )

[virtual]

Sets the shape for polygonal types.

This method can be used to set the shape. The default implementation does nothing. This is useful for objects that have a polygonal shape.

Parameters:

polygon

The new shape.

See also:

vtkQtChartShape::setRectangle(const QRectF &)

Reimplemented in vtkQtChartQuad.

virtual void vtkQtChartShape::setRectangle

(

const QRectF &

rectangle )

[virtual]

Sets the shape for rectangular types.

This method can be used to set the shape. The default implementation does nothing. This is useful for objects that have a rectangular shape.

Parameters:

rectangle

The new shape.

See also:

vtkQtChartShape::setPolygon(const QPolygonF &)

Reimplemented in vtkQtChartBar.

void vtkQtChartShape::setSeries

(

int

series )

[inline]

Sets the series number.

Parameters:

series

The new series number.

Definition at line 112 of file vtkQtChartShape.h.

{this->Series = series;}
