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::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.
