## 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.

## Member Function Documentation

### 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

### `[protected]` void QAccessibleWidget::addControllingSignal(const QString &signal)

Registers signal as a controlling signal.

An object is a Controller to any other object connected to a controlling signal.

### `[override virtual]` int QAccessibleWidget::indexOfChild(const QAccessibleInterface *child) const

### `[override virtual]` void *QAccessibleWidget::interface_cast(QAccessible::InterfaceType t)

### `[override virtual]` bool QAccessibleWidget::isValid() const

### `[override virtual]` QStringList QAccessibleWidget::keyBindingsForAction(const QString &actionName) const

### `[override virtual]` QAccessibleInterface *QAccessibleWidget::parent() const

### `[protected]` QObject *QAccessibleWidget::parentObject() const

Returns the associated widget's parent object, which is either the parent widget, or qApp for top-level widgets.

### `[override virtual]` QRect QAccessibleWidget::rect() const

### `[override virtual]` QVector<QPair<QAccessibleInterface *, QAccessible::Relation>> QAccessibleWidget::relations(QAccessible::Relation match = QAccessible::AllRelations) const

### `[override virtual]` QString QAccessibleWidget::text(QAccessible::Text t) const

### `[protected]` QWidget *QAccessibleWidget::widget() const

Returns the associated widget.

### `[override virtual]` QWindow *QAccessibleWidget::window() const
