## Detailed Description

The QAccessibleWidget class implements the QAccessibleInterface for QWidgets.

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.

### `[protected]` QAccessibleWidget::~QAccessibleWidget()

Destroys this object.

### `[virtual]` QStringList QAccessibleWidget::actionNames() const

Reimplemented from QAccessibleActionInterface::actionNames().

### `[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.

### `[virtual]` QColor QAccessibleWidget::backgroundColor() const

Reimplemented from QAccessibleInterface::backgroundColor().

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

Reimplemented from QAccessibleInterface::child().

### `[virtual]` int QAccessibleWidget::childCount() const

Reimplemented from QAccessibleInterface::childCount().

### `[virtual]` void QAccessibleWidget::doAction(const QString &actionName)

Reimplemented from QAccessibleActionInterface::doAction().

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

Reimplemented from QAccessibleInterface::focusChild().

### `[virtual]` QColor QAccessibleWidget::foregroundColor() const

Reimplemented from QAccessibleInterface::foregroundColor().

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

Reimplemented from QAccessibleInterface::indexOfChild().

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

Reimplemented from QAccessibleInterface::interface_cast().

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

Reimplemented from QAccessibleInterface::isValid().

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

Reimplemented from QAccessibleActionInterface::keyBindingsForAction().

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

Reimplemented from QAccessibleInterface::parent().

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

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

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

Reimplemented from QAccessibleInterface::rect().

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

Reimplemented from QAccessibleInterface::relations().

### `[virtual]` QAccessible::Role QAccessibleWidget::role() const

Reimplemented from QAccessibleInterface::role().

### `[virtual]` QAccessible::State QAccessibleWidget::state() const

Reimplemented from QAccessibleInterface::state().

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

Reimplemented from QAccessibleInterface::text().

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

Returns the associated widget.

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

Reimplemented from QAccessibleInterface::window().
