Loading QML objects from C++.

Homer JS

Hi guys,
"These examples":http://doc.qt.io/qt-5/qtqml-cppintegration-interactqmlfromcpp.html

I was trying to follow the instructions of Qt5.4 documentation to make QML interact with C++. I get two errors.

D:\Qt\untitled14\main.cpp:22: error: C2661: 'QQmlProperty::QQmlProperty' : no overloaded function takes 2 arguments

2)D:\Qt\untitled14\main.cpp:22: error: C2228: left of '.write' must have class/struct/union

Any help appreciated.

//main.qml
@import QtQuick 2.0

Item {
width: 100; height: 100
}@

//main.cpp

@#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QQuickView>
#include <QQuickItem>
#include <QQmlComponent>

int main(int argc, char *argv[])
{
QGuiApplication app(argc, argv);

QQmlApplicationEngine engine_e;
engine_e.load(QUrl(QStringLiteral("qrc:/main.qml")));


QQmlApplicationEngine engine;

QQmlComponent component(&engine, QUrl::fromLocalFile&#40;("main.qml"&#41;&#41;);

QObject *object = component.create();

object->setProperty("widh", 50);
QQmlProperty(object, "width").write(80);

delete object;
return app.exec&#40;&#41;;

}@

Thank You.
