Change QML object properties from C++.

Homer JS

I'm trying to do a simple task as changing a property (text: ) of some QML object from C++ yet I'm failing miserably. Any help appreciated.

I'm not getting any errors, the window shows up, just the text property doesn't change as (at least I think) it s hould. Is even anything I'm NOT doing wrong here?!!

What I was trying is this:

main.cpp
@#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QQuickView>
#include <QQuickItem>
#include <QQmlEngine>
#include <QQmlComponent>
#include <QString>

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

QQmlApplicationEngine engine;


QQmlComponent component(&engine, QUrl::fromLocalFile&#40;"main.qml"&#41;);
QObject *object = component.create();

 engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
QString thisString = "Dr. Perry Cox";

object->setProperty("text", thisString);  //<--- tried  instead of thisString putting "Dr. ..." but nope.
delete object;



return app.exec();

}@

main.qml
@
import QtQuick 2.2
import QtQuick.Window 2.1

Window {
visible: true
width: 360
height: 360

MouseArea {
    anchors.fill: parent
    onClicked: {
        Qt.quit();
    }
}

Text {
    id: whot
    text: ""
    anchors.centerIn: parent
    font.pixelSize: 20
    color: "green"
}

}@

Hi,
I think you can try this
@
QQmlApplicationEngine engine;
QQmlContext *context = engine.rootContext();
QString thisString = "Dr. Perry Cox";
context->setContextProperty("myText", thisString);
@

Hope this help

Thank you for the answer, very much appreciated. Someone helped me earlier on another website though. Good luck.
