Member Function Documentation

paint()

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

pure virtual

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

Referenced by KDChart::BarDiagram::paint(), KDChart::LineDiagram::paint(), and KDChart::AbstractArea::paintAll().

paintAll()

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

Definition at line 51 of file KDChartLayoutItems.cpp.

paintCtx()

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 59 of file KDChartLayoutItems.cpp.

parentLayout()

QLayout * KDChart::AbstractLayoutItem::parentLayout ( )

Definition at line 65 of file KDChartLayoutItems.h.

removeFromParentLayout()

void KDChart::AbstractLayoutItem::removeFromParentLayout ( )

inline

Definition at line 69 of file KDChartLayoutItems.h.

Referenced by KDChart::Chart::takeCoordinatePlane(), and KDChart::Chart::takeHeaderFooter().

setParentLayout()

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

inline

Definition at line 61 of file KDChartLayoutItems.h.

Referenced by KDChart::Chart::takeHeaderFooter().

setParentWidget()

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 46 of file KDChartLayoutItems.cpp.

References mParent, and QLayoutItem::widget().

Referenced by KDChart::HeaderFooter::setParent(), and KDChart::AbstractCartesianDiagram::takeAxis().

sizeHintChanged()

void KDChart::AbstractLayoutItem::sizeHintChanged ( ) const

virtual

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