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)

Registers signal as a controlling signal.

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

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

Reimplements: QAccessibleInterface::backgroundColor() const.

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

Reimplements: QAccessibleInterface::child(int index) const.

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

Reimplements: QAccessibleInterface::childCount() const.

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

Reimplements: QAccessibleActionInterface::doAction(const QString &actionName).

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

Reimplements: QAccessibleInterface::focusChild() const.

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

Reimplements: QAccessibleInterface::foregroundColor() const.

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

Reimplements: QAccessibleInterface::indexOfChild(const QAccessibleInterface *child) const.

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

Reimplements: QAccessibleInterface::interface_cast(QAccessible::InterfaceType type).

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

Reimplements: QAccessibleObject::isValid() const.

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

Reimplements: QAccessibleActionInterface::keyBindingsForAction(const QString &actionName) const.

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

Reimplements: QAccessibleInterface::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

Reimplements: QAccessibleObject::rect() const.

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

Reimplements: QAccessibleInterface::relations(QAccessible::Relation match) const.

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

Returns the associated widget.

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

Reimplements: QAccessibleInterface::window() const.
