Detailed Description
This class is part of 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().
See also QAccessible and QAccessibleObject.

QAccessibleWidget::QAccessibleWidget(QWidget *w, QAccessible::Role role = QAccessible::Client, const QString &name = QString())
Creates a QAccessibleWidget object for widget w. role and name are optional parameters that set the object's role and name properties.
[virtual protected] QAccessibleWidget::~QAccessibleWidget()
Destroys this object.
[override virtual] QStringList QAccessibleWidget::actionNames() const
Reimplements: QAccessibleActionInterface::actionNames() const.
[protected] void QAccessibleWidget::addControllingSignal(const QString &signal)
