メインウィンドウのqml GUIがあります。 qt quick2アプリケーションを作成し、メインウィンドウのqml GUIをコピーしてmain.qmlに貼り付けました。私は、アプリケーションを実行すると、空白のウィンドウが表示され、次は私のQMLのログです：qmlとC++ qt quick 2アプリケーション

QQuickView only supports loading of root objects that derive from QQuickItem.
If your example is using QML 2, (such as qmlscene) and the .qml file you
loaded has 'import QtQuick 1.0' or 'import Qt 4.7', this error will occur.
To load files with 'import QtQuick 1.0' or 'import Qt 4.7', use the
QDeclarativeView class in the Qt Quick 1 module.

と自動的に生成されたmain.cppに：
#include <QtGui/QGuiApplication>
#include "qtquick2applicationviewer.h"
int main(int argc, char *argv[])
{
QGuiApplication app(argc, argv);
QtQuick2ApplicationViewer viewer;
viewer.setMainQmlFile(QStringLiteral("qml/convQML/main.qml"));
viewer.showExpanded();
return app.exec();
}
これはなぜ機能しないのでしょうか？私はqmlを初めて使っていて、どうやってC++に接続しているのかは分かりません。
