#include <QGuiApplication> #include <QQmlApplicationEngine> int main(int argc, char *argv[]) { #if QT_VERSION < QT_VERSION_CHECK(6, 0, 0) QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling); #endif QGuiApplication app(argc, argv); QQmlApplicationEngine engine; const QUrl url(QStringLiteral("qrc:/main.qml")); QObject::connect(&engine, &QQmlApplicationEngine::objectCreated, &app, [url](QObject *obj, const QUrl &objUrl) { if (!obj && url == objUrl) QCoreApplication::exit(-1); }, Qt::QueuedConnection); engine.addImportPath("qrc:/"); engine.load(url); return app.exec(); }
