Подробное описание
The QAccessibleEvent class is used to query addition accessibility information about complex widgets.
The event can be of type QEvent::AccessibilityDescription or QEvent::AccessibilityHelp.
Some QAccessibleInterface implementations send QAccessibleEvents to the widget they wrap to obtain the description or help text of a widget or of its children. The widget can answer by calling setValue() with the requested information.
The default QWidget::event() implementation simply sets the text to be the widget's tooltip (for AccessibilityDescription event) or its "What's This?" text (for AccessibilityHelp event).
