QActionEvent露

PyQt5.QtGui.QActionEvent

Inherits from QEvent.

Description露

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

Actions can be added to widgets using addAction(). This generates an ActionAdded event, which you can handle to provide custom behavior. For example, QToolBar reimplements actionEvent() to create QToolButtons for the actions.
