Displaying LCD Widget of Qt in QML

[TheIndependentAquarius]

The following code compiles properly but shows NOTHING on QML window.

.cpp

#include "q.h"
 
Lcdnumber :: Lcdnumber(QGraphicsItem *parent) : QGraphicsProxyWidget(parent)
{ 
  number = new QLCDNumber();
  number->display(11);
}
 
int main (int argc, char *argv[])
{
  QApplication app (argc, argv);
 
  qmlRegisterType <Lcdnumber> ("Q", 1, 0, "Lcdnumber");
 
  QDeclarativeView view;
  view.setSource (QUrl :: fromLocalFile ("qq.qml"));
  view.show ();
 
  return app.exec();
}

#include "q.h"

Lcdnumber :: Lcdnumber(QGraphicsItem *parent) : QGraphicsProxyWidget(parent)
{ 
  number = new QLCDNumber();
  number->display(11);
}

int main (int argc, char *argv[])
{
  QApplication app (argc, argv);
  
  qmlRegisterType <Lcdnumber> ("Q", 1, 0, "Lcdnumber");

  QDeclarativeView view;
  view.setSource (QUrl :: fromLocalFile ("qq.qml"));
  view.show ();
  
  return app.exec();
}

qml

import QtQuick 1.0
import Q 1.0
 
Rectangle 
{
  id: window
  Lcdnumber 
  {
    id: button1
    anchors.centerIn: parent
    width: 600; height: 600
  }

import QtQuick 1.0
import Q 1.0

Rectangle 
{
  id: window
  Lcdnumber 
  {
    id: button1
    anchors.centerIn: parent
    width: 600; height: 600
  }
}

SOLVED

I forgot to add:

setWidget (number);

setWidget (number);

To copy to clipboard, switch view to plain text mode 

in constructor.
