setMainWidget

Peace..
hey ..
I try to compile a simple qt programm whch I found in a tuto .. but I get the following error >> 'class QApplication' has no member named 'setMainWidget'

Code:

---

#include <QApplication.h>
#include <qpainter.h>
#include <qlabel.h>
#include <qpixmap.h>
#include <qpaintdevice.h>
void Dessiner(QPaintDevice * dev)
 { }
int main (int argc, char* argv[])
 { 
  QApplication app(argc, argv) ;
  QPixmap pix(300, 200) ;
   Dessiner(&pix) ;
   QLabel label(0) ;
   label.setPixmap(pix) ;
   app.setMainWidget(&label) ;
   label.show() ;
  return app.exec() ;
 }

so is setMainWidget a member of QApplication class ??
plz help

QApplication::setMainWidget() is a method from Qt3 whereas you seem to be using Qt4.

Yea Im using Qt4 ..so wht should I put instead ?

Nothing, you can remove that line.

So by default it is taken as a main widget !!
thanks for help
