7 Event self-function:

void Accept ()
Voidignore ()
boolisaccepted () const
Voidsetaccepted (BOOL accepted)
Boolspontaneous () const
Typetype () const
Intregistereventtype (int hint =-1)

--------------------------------------------------------

Several key event handlers (in fact, are distributed in the Qobject,qwidget,qcoreapplication Class):

Qobject::event ()
Qobject::installeventfilter ()
Qwidget::event ()
Qcoreapplication::sendevent ()
Qcoreapplication::p ostevent ()
Qcoreapplication::p rocessevents ()

--------------------------------------------------------

Events (sources) are divided into three types: system-generated, QT-generated, programmer-generated
