Member Function Documentation

invalidate()

virtual void PrerenderedElement::invalidate ( ) const

protectedpure virtual

invalidate() needs to be called if any of the properties that determine the visual appearance of the prerendered element change.

It can be called for a const object, as objects may need to force recalculation of the pixmap.

Implemented in PrerenderedLabel.

pixmap()

virtual const QPixmap& PrerenderedElement::pixmap ( ) const

pure virtual

Returns the rendered element.

If any of the properties have change, the element will be regenerated.

Implemented in PrerenderedLabel.

position()

const QPointF & PrerenderedElement::position

(

)

const

Get the position of the element.

Definition at line 48 of file KChartTextLabelCache.cpp.

referencePoint()

KChartEnums::PositionValue PrerenderedElement::referencePoint

(

)

const

Get the reference point of the element.

Definition at line 58 of file KChartTextLabelCache.cpp.

referencePointLocation()

virtual QPointF PrerenderedElement::referencePointLocation ( KChartEnums::PositionValue  ) const

pure virtual

Return the location of the reference point relatively to the pixmap's origin.

Implemented in PrerenderedLabel.

setPosition()

void PrerenderedElement::setPosition

(

const QPointF &

position

)

Set the position of the element.

Definition at line 43 of file KChartTextLabelCache.cpp.

setReferencePoint()

void PrerenderedElement::setReferencePoint

(

KChartEnums::PositionValue

point

)

Set the reference point of the element.

Every element has nine possible reference points (all compass directions, plus the center.
