QT for Android 使用Item作为QML根对象

如果将main.qml中的Window替换为Rectangle,再将main.cpp修改成下面的样子；

 #include<QGuiApplication>

//#include <QQmlApplicationEngine>

#include <QQuickView>

int main(int argc, char *argv[])

{

    QGuiApplication app(argc, argv);

    QQuickView viewer;

    viewer.setResizeMode(QQuickView::SizeRootObjectToView);

    viewer.setSource(QUrl("qrc:///main.qml"));

    viewer.show();

    return app.exec();

    //QGuiApplication app(argc, argv);

    //QQmlApplicationEngine engine;

    //engine.load(QUrl(QStringLiteral("qrc:///main.qml")));

    //return app.exec();

}

这样，在main.xml文件中就可以这样写；

importQtQuick 2.2

//import QtQuick.Window 2.1

Rectangle{

    width:320;

    height: 480;

    color:"red";

    MouseArea {

        anchors.fill: parent

        onClicked: {

            Qt.quit();

        }

    }

    Text {

        text: qsTr("Hello World")

        anchors.centerIn: parent

    }

}
