Displaying qml from c++ differs from what qmlscene shows - c++

Question

I'm try to run a basic program that displays a simple qml file through c++. The code for loading QQmlEngine etc looks like this:
#include <QQmlEngine>
#include <QQmlComponent>
#include <QDebug>
#include <QGuiApplication>
#include <QQuickView>
int main(int argc, char *argv[])
{
QGuiApplication app(argc, argv);
QQmlEngine engine;
QQmlComponent component(&engine);
QQuickWindow::setDefaultAlphaBuffer(true);
component.loadUrl(QUrl("qrc:///qmlFiles/main.qml"));
if ( component.isReady() )
component.create();
else
qWarning() << component.errorString();
QObject::connect(&engine, SIGNAL(quit()), QCoreApplication::instance(),SLOT(quit()));
return app.exec();
}
and the qml (simplified) file is:
import QtQuick 2.0
import QtQuick.Controls 1.0
import QtQuick.Dialogs 1.0
ApplicationWindow
{
width:800
height:600
//background: "white"
visible:true
function selectFile()
{
fileChooser.visible=true;
}
menuBar:MenuBar {
Menu{
title:"File"
MenuItem{
text:"Choose File"
shortcut: "Ctrl+F"
onTriggered:{
selectFile();
}
}
MenuItem {
text:"Quit"
shortcut: "Ctrl+Q"
onTriggered: Qt.quit()
}
}
}
FileDialog{
id:fileChooser
visible:false
modality:Qt.WindowModal
title:"Choose data file"
onAccepted:{
console.log(fileChooser.fileUrls)
visible:false
}
onRejected:{
console.log("Cancel")
visible:false
}
}
}
When I run the file from terminal using qmlscene the displayed looks different than while running it from the c++ program.
My guess is that the C++ implementation is unable to use platform specific stuff (for example QFileDialog) and falls back to qml implementation of the stuff.
I guess I need to load the qml file differently, but how?

Answer 1

Turns out there is some overriding or something with QGuiApplication .
Changed it to QApplication and looks as nice as in qmlscene.
