Output is there..but code doesnt look to be Perfect..!

Hi..
I had tried to show a layout of buttons on View..it worked fine,but the return function ( retWidg() ) which i have specified in the main doesnt seems to be necessary..i mean to say is there any other solution by which i can avoid these statement and with it be more cleared in approach...

#include "exclass.h"
 
#include <QApplication>
#include <QGraphicsScene>
 
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
 
exclass *w = new exclass;
 
QWidget *mainW = new QWidget;
QGraphicsScene scene;
QGraphicsView view;
 
mainW = w->retWidg();
scene.addWidget(mainW);
scene.addItem(w);
 
view.setScene(&scene);
 
view.show();
return a.exec();
}
