Charts crash my application

ODБOï

hi,
If i create a ChartView in QML and run my app it will crash with this error :

ASSERT: "!"No style available without QApplication!"" in file kernel\qapplication.cpp, line 1051
Invalid parameter passed to C runtime function.
Invalid parameter passed to C runtime function.
ASSERT: "!"No style available without QApplication!"" in file kernel\qapplication.cpp, line 1051

Invalid parameter passed to C runtime function.
C:/Users/zer/Documents/build-Test-Desktop_Qt_5_11_0_MinGW_32bit2-Debug/debug/Test.exe exited with code 3

Why ?

Qt_5_11_0_MinGW_32bit2

.qml

import QtQuick 2.10
import QtQuick.Window 2.10
import QtCharts 2.2

Window {
    visible: true
    width: 640
    height: 480
    title: qsTr("QChartCrash")
       ChartView {
               title: "chart"
           }
}

.cpp

#include <QGuiApplication>
#include <QQmlApplicationEngine>

int main(int argc, char *argv[])
{
    QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
    QGuiApplication app(argc, argv);
    QQmlApplicationEngine engine;
    engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
    if (engine.rootObjects().isEmpty())
        return -1;
    return app.exec();
}

.pro

QT += quick
QT+= charts
QT += widgets
CONFIG += c++11
DEFINES += QT_DEPRECATED_WARNINGS
SOURCES += main.cpp
RESOURCES += qml.qrc
qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

thx

Hi,

Replace your QGuiApplication with a QApplication as the error message suggests.
