Member Function Documentation

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

Definition at line 72 of file KDChartLayoutItems.cpp.

References KDChart::PaintContext::painter().

QLayout* KDChart::AbstractLayoutItem::parentLayout ( )

void KDChart::AbstractLayoutItem::removeFromParentLayout ( )
void KDChart::AbstractLayoutItem::setParentLayout ( QLayout *  lay)
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.

Definition at line 59 of file KDChartLayoutItems.cpp.

References mParent.

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

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