Detailed Description

The QActionEvent class provides an event that is generated when a QAction is added, removed, or changed.

\inmodule QtGui

Actions can be added to controls, for example by using QWidget::addAction(). This generates an \l ActionAdded event, which you can handle to provide custom behavior. For example, QToolBar reimplements QWidget::actionEvent() to create \l{QToolButton}s for the actions.
