void KDChart::AutoSpacerLayoutItem::paint ( QPainter *  painter )

virtual

Implements KDChart::AbstractLayoutItem.

Definition at line 1022 of file KDChartLayoutItems.cpp.

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

virtualinherited

Default impl: just call paint.

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

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

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

virtualinherited

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 )

virtualinherited

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.

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