Detailed Description

The QAccessibleEvent class is the base class for accessibility notifications. This class was designed to be used with QAccessible::updateAccessibility(). There is an event type associated with every QAccessibleEvent object. Several subclasses exist which can be used to provide more details.

As an example, to notify all QAccessible clients about a focus change when overriding QWidget::setFocus, consider using the following code. All accessible events must be sent after the user interface has been updated.

void MyWidget::setFocus(Qt::FocusReason reason) {
   // handle custom focus setting
 
   QAccessibleEvent event(this, QAccessible::Focus);
   QAccessible::updateAccessibility(&event);
}
