How to convert QGuiApplication to QApplication ?

Aminsl

I'm trying to use PolarChartView in Qt6 and writing the code in qt creator 10 but when I run my code , the application crashes and the console log says it just crashed. I figured out that I have to change QGuiApplication to QApplication and I made these configurations to my main.cpp file but I got these errors :
:-1: error: D:/CppProjects/RadarChart/main.cpp:17: undefined reference to `__imp__ZN12QApplicationD1Ev'
:-1: error: D:/CppProjects/build-radarchart-Desktop_Qt_6_5_1_MinGW_64_bit-Debug/Debug_Desktop__9a53abaa43e654f2/radarchart.8c396ce1/3a52ce780950d4d9/main.cpp.o:D:/CppProjects/RadarChart/main.cpp:7: undefined reference to `__imp__ZN12QApplicationC1ERiPPci'

And this is my main.cpp file :

#include <QtWidgets/QApplication>
#include <QQmlApplicationEngine>


int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QQmlApplicationEngine engine;
    const QUrl url(u"qrc:/RadarChart/Main.qml"_qs);
    QObject::connect(&engine, &QQmlApplicationEngine::objectCreationFailed,
        &app, []() { QCoreApplication::exit(-1); },
        Qt::QueuedConnection);
    engine.load(url);

    return app.exec();
}

@Aminsl So, do you have

Depends { name: "Qt.widgets" }

?

Hi,

Did you add QT += widgets to your .pro file ?

@SGaist I'm using Qbs so I don't have .pro file
