Member Function Documentation

◆ paintAll()

void KChart::AbstractLayoutItem::paintAll ( QPainter painter)
virtual

Default impl: just call paint.

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

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

Definition at line 40 of file KChartLayoutItems.cpp.

◆ paintCtx()

void KChart::AbstractLayoutItem::paintCtx ( PaintContext context)
virtual

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

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

Definition at line 45 of file KChartLayoutItems.cpp.

◆ setParentWidget()

void KChart::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.

Definition at line 35 of file KChartLayoutItems.cpp.

◆ sizeHintChanged()

void KChart::AbstractLayoutItem::sizeHintChanged ( ) const
virtual

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

Definition at line 51 of file KChartLayoutItems.cpp.
