.SH DESCRIPTION
The QCustomEvent class provides support for custom events.
.PP
QCustomEvent is a user-defined event type which contains a \fCvoid*.
.PP
\fBWarning:\fR\fR This event class is internally used to implement Qt enhancements. It is not advisable to use QCustomEvent in normal applications, where other event types and the signal/slot mechanism can do the job.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QCustomEvent::QCustomEvent ( Type type, void * data )"
Constructs a custom event object with the event type \fItype\fR and a pointer to \fIdata.\fR
.SH "void * QCustomEvent::data () const"
Returns a pointer to the event data (specified in the constructor).
.PP
The event data can be anything and must be cast to something useful
based on the event type. Again, it is not
recommended to use custom events unless you are implementing Qt kernel
enhancements.
