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 - } -.br -.fi -.PP -See also QWidget::customEvent(), QApplication::notify(), and Event Classes. -.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(). - -.SH "SEE ALSO" -.BR http://doc.trolltech.com/qcustomevent.html -.BR http://www.trolltech.com/faq/tech.html -.SH COPYRIGHT -Copyright 1992-2007 Trolltech ASA, http://www.trolltech.com.
