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 KDChart::AbstractLayoutItem::mParent.
