Solved ChartView with qml
-
I'm trying to use a ChartView on my qml code, like this
Rectangle { anchors.fill: parent color:"lightSteelBlue" BackEnd{ id:myBackEnd } ChartView { width: 400 height: 300 theme: ChartView.ChartThemeBrownSand antialiasing: true PieSeries { id: pieSeries PieSlice { label: "eaten"; value: 94.9 } PieSlice { label: "not yet eaten"; value: 5.1 } } } Button{ ... //This is my main function int main(int argc, char *argv[]) { qmlRegisterType<BackEnd>("BackEnd", 1, 0, "BackEnd" ); QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling); QGuiApplication app(argc, argv); mediator *m = new mediator(); QQmlApplicationEngine engine; engine.rootContext()->setContextProperty("mediator",m); engine.load(QUrl(QStringLiteral("qrc:/main.qml"))); if (engine.rootObjects().isEmpty()) return -1; return app.exec(); }
And this is the error I'm receiving
"ASSERT: "!"No style available without QApplication!"" in file kernel\qapplication.cpp, line 1065"I've already try most solutions around internet, none worked

Hi
And you have the normal main.cpp that creates
a QApplication instance ?#include <QApplication> #include <QQmlApplicationEngine> int main(int argc, char *argv[]) { QApplication app(argc, argv); QQmlApplicationEngine engine; engine.load(QUrl(QStringLiteral("qrc:/main.qml"))); return app.exec(); }

@mrjj
no, I had "QGuiApplication app(argc, argv);" instead of " QApplication app(argc, argv);
" I just changed this line and everything works fine ! thank you!!
