The event() function can be reimplemented to customize the
behavior of an object.
+ Make sure you call the parent event class implementation
+ for all the events you did not handle.

+ Example:

+ \snippet code/src_corelib_kernel_qobject.cpp 52
+
\sa installEventFilter(), timerEvent(), QCoreApplication::sendEvent(),
QCoreApplication::postEvent()
