Detailed Description

Base class for all layout items of KChart.

Definition at line 38 of file KChartLayoutItems.h.

Constructor & Destructor Documentation

AbstractLayoutItem()

KChart::AbstractLayoutItem::AbstractLayoutItem ( Qt::Alignment itemAlignment = Qt::Alignment() )

inline

Definition at line 41 of file KChartLayoutItems.h.

Member Function Documentation

paint()

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

pure virtual

Implemented in KChart::CartesianAxis, KChart::CartesianCoordinatePlane, and KChart::PolarCoordinatePlane.

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

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

Definition at line 45 of file KChartLayoutItems.cpp.

parentLayout()

QLayout * KChart::AbstractLayoutItem::parentLayout ( )

inline

Definition at line 81 of file KChartLayoutItems.h.

removeFromParentLayout()

void KChart::AbstractLayoutItem::removeFromParentLayout ( )

inline

Definition at line 85 of file KChartLayoutItems.h.

setParentLayout()

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

inline

Definition at line 77 of file KChartLayoutItems.h.

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.
