45 \class QEvent-
46 \inmodule QtCore-
47 \brief The QEvent class is the base class of all-
48 event classes. Event objects contain event parameters.-
49-
50 \ingroup events-
51-
52 Qt's main event loop (QCoreApplication::exec()) fetches native-
53 window system events from the event queue, translates them into-
54 QEvents, and sends the translated events to \l{QObject}s.-
55-
56 In general, events come from the underlying window system-
57 (spontaneous() returns \c true), but it is also possible to manually-
58 send events using QCoreApplication::sendEvent() and-
59 QCoreApplication::postEvent() (spontaneous() returns \c false).-
60-
61 \l {QObject}{QObjects} receive events by having their QObject::event() function-
62 called. The function can be reimplemented in subclasses to-
63 customize event handling and add additional event types;-
64 QWidget::event() is a notable example. By default, events are-
65 dispatched to event handlers like QObject::timerEvent() and-
66 QWidget::mouseMoveEvent(). QObject::installEventFilter() allows an-
67 object to intercept events destined for another object.-
68-
69 The basic QEvent contains only an event type parameter and an-
70 "accept" flag. The accept flag set with accept(), and cleared-
71 with ignore(). It is set by default, but don't rely on this as-
72 subclasses may choose to clear it in their constructor.-
73-
74 Subclasses of QEvent contain additional parameters that describe-
75 the particular event.-

244 For convenience, you can use the registerEventType() function to-
245 register and reserve a custom event type for your-
246 application. Doing so will allow you to avoid accidentally-
247 re-using a custom event type already in use elsewhere in your-
248 application.-
