/ 24 марта 2020

Я новичок в qml и пытаюсь протестировать простое приложение hello world с использованием файла qml в qt 5.9. Я уже добавил qt+= quick в свой файл .pro, но каждый раз, когда я пытаюсь включить <qtquick> или <qquickview> это происходит: 

warning : the code model could not parse an included file which might lead to incorrect code compilation and highlighting for example.

, поэтому я пытаюсь создать привет мир, поэтому я включаю <qtquick> создать экземпляр qquickview, связанный с источником URL-адреса, и выполнить его 

#include <QGuiApplication>
#include <QQuickView>

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

    QQuickView view;
    view.setSource(QUrl("qrc:/main.qml"));
    view.show();

    return app.exec();
}

мой .pro файл
