Public Member Functions | |
AbstractLayoutItem (Qt::Alignment itemAlignment=0) | |
virtual void | paint (QPainter *)=0 |
virtual void | paintAll (QPainter &painter) |
Default impl: just call paint. | |
virtual void | paintCtx (PaintContext *context) |
Default impl: Paint the complete item using its layouted position and size. | |
QLayout * | parentLayout () |
void | removeFromParentLayout () |
void | setParentLayout (QLayout *lay) |
virtual void | setParentWidget (QWidget *widget) |
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. | |
virtual void | sizeHintChanged () const |
Report changed size hint: ask the parent widget to recalculate the layout. | |

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, and KDChart::TernaryCoordinatePlane.
Referenced by KDChart::Legend::paint(), paintAll(), KDChart::AbstractArea::paintAll(), and paintCtx().
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.

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.
