DESCRIPTION
       The QEvent class is the base class of all event classes. Event objects
       contain event parameters.

       Qt's main event loop (QApplication::exec()) fetches native window
       system events from the event queue, translates them into QEvents and
       sends the translated events to QObjects.

       In general, events come from the underlying window system
       (spontaneous() returns TRUE) but it is also possible to manually send
       events using QApplication::sendEvent() and QApplication::postEvent()
       (spontaneous() returns FALSE).

       QObjects receive events by having their QObject::event() function
       called. The function can be reimplemented in subclasses to customize
       event handling and add additional event types; QWidget::event() is a
       notable example. By default, events are dispatched to event handlers
       like QObject::timerEvent() and QWidget::mouseMoveEvent().
       QObject::installEventFilter() allows an object to intercept events
       destined for another object.

       The basic QEvent contains only an event type parameter. Subclasses of
       QEvent contain additional parameters that describe the particular
       event.

       See also QObject::event(), QObject::installEventFilter(),
       QWidget::event(), QApplication::sendEvent(), QApplication::postEvent(),
       QApplication::processEvents(), Environment Classes, and Event Classes.
