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.
