How to take ScreenShot Qt/QML

This is the example of QtQuick1
http://www.developer.nokia.com/Commu...eenShot_Qt/QML
I canâ€™t make it work on QtQuick2

screenCapture.hpp

Code:

#include <QObject>
 
    class QString;
    class QQuickView;
 
    class screenCapture : public QObject
    {
        Q_OBJECT
    public:    
        explicit screenCapture(QQuickView *parent = 0);
 
    public slots:
        void capture(QString const &path) const;
 
    private:
        QQuickView *currentView_;    
    };

Code:

screenCapture.cpp
 
    #include <QPixmap>
    #include <QQuickView>
    #include <QString>
 
    #include "screenCapture.hpp"
 
    screenCapture::screenCapture(QQuickView *currentView) :
        QObject(0), currentView_(currentView)
    {
    }
 
    void screenCapture::capture(QString const &path) const
    {
        QPixmap::grabWidget(currentView_).save(path);
    }

Code:

main.cpp
 
    #include <QGuiApplication>
    #include <QQuickPaintedItem>
    #include <QQuickView>
    #include <QQmlContext>
 
    #include "screenCapture.hpp"
 
    int main(int argc, char *argv[])
    {
        QGuiApplication app(argc, argv);
 
        qmlRegisterType<screenCapture>("Image", 1, 0, "ScreenCapture");
        qmlRegisterType<saveAbleImage>("Image", 1, 0, "SaveAbleImage");
 
        QQuickView view;
        view.setResizeMode(QQuickView::SizeRootObjectToView);
        view.setSource(QStringLiteral("/Users/Qt/program/experiment_apps_and_libs/funnyCamera/qml/funnyCamera/main.qml"));
        view.show();
 
        screenCapture screenClass(&view);
        view.rootContext()->setContextProperty("screenObject", &screenClass);
 
        return app.exec();
    }

Code:

main.qml
 
    import QtQuick 2.0
 
    Rectangle{
        id : root
        width : 1024
        height : 768    
 
        MouseArea{
            anchors.fill: root
 
            onClicked: {          
                console.log("save image")
                screenObject.capture("Pictures/saveTest.jpg")
            }
        }
    }

error message

QPixmap::grabWidget is deprecated, use QWidget::grab() instead
QMetaObject::invokeMethod: No such method QQuickView::grab(QRect)

Added after 1 2 minutes:

I found a solution, pretty simple, change the function â€œcaptureâ€ to

Code:

void screenCapture::capture(QString const &path) const
    {
        QImage img = currentView_->grabWindow();
        img.save(path);
    }
