Detailed Description

A text area in the chart with a background, a frame, etc.

TextArea is the base class for all text containing non-widget chart elements that have a set of background attributes and frame attributes, such as headers or footers.

Note:
This class inherits from AbstractAreaBase, TextLayoutItem, QObject. The reason for this tripple inheritance is that neither AbstractAreaBase nor TextLayoutItem are QObject.

void KDChart::AbstractLayoutItem::setParentWidget ( QWidget widget  )  [virtual, inherited]

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.
