Copied some example code but getting an error

I knew I am asking too many questions today but I promise this is the last one.

I got the calculator code from "here":http://www.trinitydesktop.org/docs/qt4/script-calculator.html
and made a project and put .js and .ui file in to that directory and copied main.cpp and qrc files

But in main.cpp some includes could not be found so I changed from :

then and there is no warning they are found or not

@ #include <QApplication>
#include <QUiLoader>
#include <QtScript>
#include <QWidget>
#include <QFile>
#include <QMainWindow>
#include <QLineEdit>

#ifndef QT_NO_SCRIPTTOOLS
#include <QScriptEngineDebugger>
#endif@

to :

@ #include <QApplication>
#include <QtUiTools/QUiLoader>
#include <QtScript/QtScript>
#include <QWidget>
#include <QFile>
#include <QMainWindow>
#include <QLineEdit>

#ifndef QT_NO_SCRIPTTOOLS
#include <QtScriptTools/QScriptEngineDebugger>
#endif@

But I when I try to run it , I get this error ; I don't what does it mean.

@D:\qt\owo\main.cpp:45: error: C2065: 'qFindChild' : undeclared identifier

D:\qt\owo\main.cpp:45: error: C2059: syntax error : '>'@

also "here ":http://s10.postimg.org/nmb239w6h/Scrshot13.pngis the screen shot

hmmm.... i can't find the method qFindChild in the docs?! Only qFindChildren()
You could change the line to this though:
@
QLineEdit* lineEdit = qFindChildren<QLineEdit*>(ui, "display").first(); // #include <QObject>
@
