Detailed Description

The QAccessibleWidget class implements the QAccessibleInterface for QWidgets.

\inmodule QtWidgets

This class is part of \l {Accessibility for QWidget Applications}.

This class is convenient to use as a base class for custom implementations of QAccessibleInterfaces that provide information about widget objects.

The class provides functions to retrieve the parentObject() (the widget's parent widget), and the associated widget(). Controlling signals can be added with addControllingSignal(), and setters are provided for various aspects of the interface implementation, for example setValue(), setDescription(), setAccelerator(), and setHelp().
