QT 自定义消息（超级简单的一个例子）

#define TEST_EVENT QEvent::User + 100

 

class CVxActuatorMain : public QMainWindow

{

  protected:

      void customEvent(QEvent *event);

}

 

CVxActuatorMain::CVxActuatorMain(QWidget *parent, Qt::WFlags flags)
 : QMainWindow(parent, flags)
{
     QEvent *event = new QEvent(QEvent::Type(TEST_EVENT));
     qApp->postEvent(this, event);

}

 

void CVxActuatorMain::customEvent(QEvent *event)
{
     int type = event->type();
     if (type == TEST_EVENT) 
     {
          m_pEdt_Info->append(QObject::tr("Test"));
          event->accept();
     }
     else
     {
          QMainWindow::customEvent(event); 
     }
}
