使用QQmlApplicationEngine运行qml

程序结构如下：

源码如下：

main.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(); }

main.qml

import QtQuick 2.9 import QtQuick.Window 2.2 Window { visible: true width: 640 height: 480 title: qsTr("Hello World") Text { anchors.centerIn: parent id: text text: qsTr("Hello World") color: "red" font.pointSize: 30 } Component.onCompleted: { console.debug("finished") } }
