Inheritance diagram for KDChart::AbstractLayoutItem:
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. | |
Protected Attributes | |

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 64 of file KDChartLayoutItems.cpp. References mParent. Referenced by KDChart::Legend::buildLegend(), and KDChart::AbstractCartesianDiagram::takeAxis().
00065 { 00066 mParent = widget; 00067 } |

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