Member Function Documentation

virtual bool vtkQtChartQuad::contains

(

const QPointF &

point )

const [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.

Implements vtkQtChartShape.

virtual void vtkQtChartQuad::getBounds

(

QRectF &

bounds )

const [virtual]

Gets the bounding box for the shape.

Parameters:

bounds

Used to return the bounding box.

Implements vtkQtChartShape.

const QPolygonF& vtkQtChartQuad::getPoints

(

)

const

Gets the list of quad points.

Returns:

The list of quad points.

virtual bool vtkQtChartQuad::intersects

(

const QRectF &

area )

const [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.

Implements vtkQtChartShape.

vtkQtChartQuad& vtkQtChartQuad::operator=

(

const vtkQtChartQuad &

other )

void vtkQtChartQuad::setPoint	(	int	index,
		const QPointF &	point
	)

Sets the point for the given index.

Parameters:

index	The index of the quad point.
point	The new point.

void vtkQtChartQuad::setPoints

(

const QPolygonF &

points )

Sets the quad shape.

Parameters:

points

The list of points to define the quad.

virtual void vtkQtChartQuad::setPolygon

(

const QPolygonF &

polygon )

[inline, virtual]

Sets the quad shape.

The polygon should be a list of four points. The points should form a convex, clock-wise loop.

Parameters:

polygon

The list of points to define the quad.

Reimplemented from vtkQtChartShape.
