+.SH DESCRIPTION
+The QCustomEvent class provides support for custom events.
+.PP
+QCustomEvent is a generic event class for user-defined events. User defined events can be sent to widgets or other QObject instances using QApplication::postEvent() or QApplication::sendEvent(). Subclasses of QObject can easily receive custom events by implementing the QObject::customEvent() event handler function.
+.PP
+QCustomEvent objects should be created with a type ID that uniquely identifies the event type. To avoid clashes with the Qt-defined events types, the value should be at least as large as the value of the "User" entry in the QEvent::Type enum.
+.PP
+QCustomEvent contains a generic void* data member that may be used for transferring event-specific data to the receiver. Note that since events are normally delivered asynchronously, the data pointer, if used, must remain valid until the event has been received and processed.
+.PP
+QCustomEvent can be used as-is for simple user-defined event types, but normally you will want to make a subclass of it for your event types. In a subclass, you can add data members that are suitable for your event type.
+.PP
+Example:
+.PP
+.nf
+.br
+    class ColorChangeEvent : public QCustomEvent
+.br
+    {
+.br
+    public:
+.br
+        ColorChangeEvent( QColor color )
+.br
+            : QCustomEvent( 65432 ), c( color ) {}
+.br
+        QColor color() const { return c; }
+.br
+    private:
+.br
+        QColor c;
+.br
+    };
+.br
+.br
+    // To send an event of this custom event type:
+.br
+.br
+    ColorChangeEvent* ce = new ColorChangeEvent( blue );
+.br
+    QApplication::postEvent( receiver, ce );  // Qt will delete it when done
+.br
+.br
+    // To receive an event of this custom event type:
+.br
+.br
+    void MyWidget::customEvent( QCustomEvent * e )
+.br
+    {
+.br
+        if ( e->type() == 65432 ) {  // It must be a ColorChangeEvent
+.br
+            ColorChangeEvent* ce = (ColorChangeEvent*)e;
+.br
+            newColor = ce->color();
+.br
+        }
+.br
+    }

+.SH MEMBER FUNCTION DOCUMENTATION
+.SH "QCustomEvent::QCustomEvent ( int type )"
+Constructs a custom event object with event type \fItype\fR. The value of \fItype\fR must be at least as large as QEvent::User. The data pointer is set to 0.
+.SH "QCustomEvent::QCustomEvent ( Type type, void * data )"
+Constructs a custom event object with the event type \fItype\fR and a pointer to \fIdata\fR. (Note that any int value may safely be cast to QEvent::Type).
+.SH "void * QCustomEvent::data () const"
+Returns a pointer to the generic event data.
+.PP
+See also setData().
+.SH "void QCustomEvent::setData ( void * data )"
+Sets the generic data pointer to \fIdata\fR.
+.PP
+See also data().
