Detailed Description

An area in the chart with a background, a frame, etc.

AbstractArea is the base class for all non-widget chart elements that have a set of background attributes and frame attributes, such as coordinate planes or axes.

Note: This class inherits from AbstractAreaBase, AbstractLayoutItem, QObject. The reason for this triple inheritance is that neither AbstractAreaBase nor AbstractLayoutItem are QObject.

◆ areaGeometry()

QRect AbstractArea::areaGeometry ( ) const

overrideprotectedvirtual

Implements KDChart::AbstractAreaBase.

Referenced by KDChart::CartesianCoordinatePlane::drawingArea(), KDChart::PolarCoordinatePlane::layoutDiagrams(), KDChart::TernaryCoordinatePlane::layoutDiagrams(), KDChart::CartesianAxis::paint(), KDChart::TernaryCoordinatePlane::paint(), paintAll(), and KDChart::CartesianAxis::paintCtx().

◆ bottomOverlap()

int AbstractArea::bottomOverlap ( bool doNotRecalculate = false ) const

virtual

This is called at layout time by KDChart:AutoSpacerLayoutItem::sizeHint().

The method triggers AbstractArea::sizeHint() to find out the amount of overlap at the bottom edge of the area.

Note: The default implementation is not using any caching, it might make sense to implement a more sophisticated solution for derived classes that have complex work to do in sizeHint(). All we have here is a primitive flag to be set by the caller if it is sure that no sizeHint() needs to be called.

◆ leftOverlap()

int AbstractArea::leftOverlap ( bool doNotRecalculate = false ) const

virtual

This is called at layout time by KDChart::AutoSpacerLayoutItem::sizeHint().

The method triggers AbstractArea::sizeHint() to find out the amount of overlap at the left edge of the area.

Note: The default implementation is not using any caching, it might make sense to implement a more sophisticated solution for derived classes that have complex work to do in sizeHint(). All we have here is a primitive flag to be set by the caller if it is sure that no sizeHint() needs to be called.

◆ paintAll()

void AbstractArea::paintAll ( QPainter & painter )

overridevirtual

Call paintAll, if you want the background and the frame to be drawn before the normal paint() is invoked automatically.

Reimplemented from KDChart::AbstractLayoutItem.

Reimplemented in KDChart::TernaryAxis.

Definition at line 102 of file KDChartAbstractArea.cpp.

References areaGeometry(), d, KDChart::AbstractAreaBase::innerRect(), KDChart::AbstractLayoutItem::paint(), KDChart::AbstractAreaBase::paintBackground(), and KDChart::AbstractAreaBase::paintFrame().

Referenced by paintIntoRect().

◆ paintIntoRect()

void AbstractArea::paintIntoRect	(	QPainter &	painter,
		const QRect &	rect
	)

virtual

Draws the background and frame, then calls paint().

In most cases there is no need to overwrite this method in a derived class, but you would overwrite AbstractLayoutItem::paint() instead.

◆ rightOverlap()

int AbstractArea::rightOverlap ( bool doNotRecalculate = false ) const

virtual

This is called at layout time by KDChart::AutoSpacerLayoutItem::sizeHint().

The method triggers AbstractArea::sizeHint() to find out the amount of overlap at the right edge of the area.

Note: The default implementation is not using any caching, it might make sense to implement a more sophisticated solution for derived classes that have complex work to do in sizeHint(). All we have here is a primitive flag to be set by the caller if it is sure that no sizeHint() needs to be called.

◆ topOverlap()

int AbstractArea::topOverlap ( bool doNotRecalculate = false ) const

virtual

This is called at layout time by KDChart::AutoSpacerLayoutItem::sizeHint().

The method triggers AbstractArea::sizeHint() to find out the amount of overlap at the top edge of the area.

Note: The default implementation is not using any caching, it might make sense to implement a more sophisticated solution for derived classes that have complex work to do in sizeHint(). All we have here is a primitive flag to be set by the caller if it is sure that no sizeHint() needs to be called.
