virtual void KDChart::AbstractLayoutItem::paint ( QPainter *  )

pure virtual

Implemented in KDChart::AutoSpacerLayoutItem, KDChart::CartesianCoordinatePlane, KDChart::VerticalLineLayoutItem, KDChart::HorizontalLineLayoutItem, KDChart::LineWithMarkerLayoutItem, KDChart::LineLayoutItem, KDChart::MarkerLayoutItem, KDChart::TextBubbleLayoutItem, KDChart::PolarCoordinatePlane, KDChart::TextLayoutItem, KDChart::CartesianAxis, KDChart::TernaryAxis, and KDChart::TernaryCoordinatePlane.

Referenced by KDChart::Legend::paint(), paintAll(), KDChart::AbstractArea::paintAll(), and paintCtx().

void KDChart::AbstractLayoutItem::paintAll ( QPainter &  painter )

virtual

Default impl: just call paint.

Derived classes like KDChart::AbstractArea are providing additional action here.

Reimplemented in KDChart::AbstractArea, KDChart::TextArea, and KDChart::TernaryAxis.

Definition at line 64 of file KDChartLayoutItems.cpp.

void KDChart::AbstractLayoutItem::paintCtx ( PaintContext *  context )

virtual

Default impl: Paint the complete item using its layouted position and size.

Reimplemented in KDChart::CartesianAxis, KDChart::LeveyJenningsAxis, and KDChart::TernaryAxis.

void KDChart::AbstractLayoutItem::setParentWidget ( QWidget *  widget )

virtual

Inform the item about its widget: This enables the item, to trigger that widget's update, whenever the size of the item's contents has changed.

Thus, you need to call setParentWidget on every item, that has a non-fixed size.

void KDChart::AbstractLayoutItem::sizeHintChanged ( ) const

virtual

Report changed size hint: ask the parent widget to recalculate the layout.
