Setting Up StackView's initialItem property from c++.

Gurubaran

I want to set up the initialItem of StackView from c++,
This is my code
main.cpp
@
int main(int argc, char *argv[])
{
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
QGuiApplication app(argc, argv);
QQmlApplicationEngine engine;
engine.load(QUrl(QLatin1String("qrc:/main.qml")));
QObject *rootObject = engine.rootObjects().first();
QObject stack = rootObject->findChild<QObject>("pageStack");
if(stack)
{
stack->setProperty("initialItem" , "qrc:/newPage.qml");
}
qDebug() << "initialItem :" << stack->property("initialItem").toString(); **/prints output as - > initialItem : "qrc:/newPage.qml" /
if(engine.rootObjects().isEmpty())
return -1;

return app.exec();

}
@
main.qml
@
import QtQuick 2.9
import QtQuick.Controls 2.2
import QtQuick.Layouts 1.3

ApplicationWindow {
id: mainWindow
visible: true
width: 1024
height: 768

Rectangle {
    color: "#ffffff"
    anchors.fill: parent
    objectName: "rect"

}
StackView {
    id: stackView
    objectName: "pageStack"
    anchors.fill: parent
}

}
@

The property is getting set (from the debug message) but it is not moving to that specified url. Please help understand what i am doing wrong. Thanks in advance

I know nothing about QML, but your property name has space-colon on the end of it:

stack->setProperty("initialItem :" , "qrc:/newPage.qml");

I would have thought it should be just initialItem, as in your stack->property("initialItem").toString(), no?

Gurubaran

I moved the content of main.qml to MainWindow.qml and implemented a Loader qml type with a Timer qml type (to give a small delay before loading the first qml page) on main.qml, this solved the problem.

If there is any better Solution please let me know .
Thank You.

Consider:

Component.onCompleted: {
    stackView.push("newPage.qml")
}

@Tom_H said in Setting Up StackView's initialItem property from c++.:

@Gurubaran
Consider:

Component.onCompleted: {
    stackView.push("newPage.qml")
}

That's a more verbose way to write initialItem: "newPage.qml".

@GrecKo
Yes, I didn't understand why he wanted to do it from C++ or then use a timer. But of course you are right.
