Detailed Description

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 QToolButton for the actions.
