Hi,

Please read the following code snippets;

class WorkerThread : public QThread
{
    public :
          WorkerThread () : QThread ()
           {
            }  
      
    protected:
        void run ();
};


void
WorkerThread :: run ()
{
    QWidget* widget =  new QWidget;
     widget->show ();
}

class MyWidget : public QWidget
{
    public:
          MyWidget () : QWidget 
          {
                    QPushButton* pb = new QPushButtoon ("Create Widget 
on Thread", this);
                   connect (pb, SIGNAL (clicked ()), this, SLOT 
(createWorkerThread ()));

          }

    public slots:
      
        void createWorkerThread ()
         {
                WorkerThread* thr1 =  new WorkerThread;
                 thr1->start ();
         }
};


int main (int n, char** c)
{
    QApplication app (n,c);
    MyWidget w;
    w.show ()
    app.exec ();
}



Will the above program work?
Can I create / show GUI elements in Worker Thread?
Please help me somebody by answering these simple qns.
