Changes to the QML object in the QT Widgets Application

pirates21

Can I change the properties of the QML object in the application in "QT widgets Application" (during the program)?
So far, I did as in the given code:

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);

connect(ui->pushButton, SIGNAL(clicked()), qApp, SLOT(quit()));

QQuickView *view = new QQuickView();
QWidget *container = QWidget::createWindowContainer(view, this);
container->setMinimumSize(200, 200);
container->setMaximumSize(200, 200);
container->setFocusPolicy(Qt::TabFocus);
view->setSource(QUrl("/home/newuser/widgetsandqml/main.qml"));
ui->verticalLayout->addWidget(container);

QObject *item = view->rootObject();
item->setProperty("width",500);
}
I would like to change the property in the QML file after pressing "Button"
If you can do that, please, for example.

Hi,

You should take a look at the Overview - QML and C++ Integration chapter in Qt's documentation.
