public class QActionEvent
extends QEvent

The QActionEvent class provides an event that is generated when a QAction is added, removed, or changed. Actions can be added to widgets using QWidget::addAction(). This generates an ActionAdded event, which you can handle to provide custom behavior. For example, QToolBar reimplements QWidget::actionEvent() to create QToolButtons for the actions.

QAction, QWidget::addAction(), QWidget::removeAction(), and QWidget::actions().
