      [quote author="JKSH" date="1399449048"]Hi,

      QDeclarativeView is for Qt Quick 1.

      For Qt Quick 2, you have 2 options:

      • Use QQuickView and QWidget::createWindowContainer(): https://blog.qt.digia.com/blog/2013/02/19/introducing-qwidgetcreatewindowcontainer/ (Requires Qt 5.1 and above)
      • Use "QQuickWidget":http://doc-snapshot.qt-project.org/qt5-release/qquickwidget.html (Requires Qt 5.3 and above)

      [quote author="Kamb!z" date="1399448588"]
      QT += core gui qml quick declarative[/quote]Remove "declarative". That is for Qt Quick 1 only.[/quote]

          Are you using an OpenGL version of Qt, or an ANGLE version?

          Does your graphics card support OpenGL 2.0?

          In Qt Creator, start a new Qt Quick project:

          File -> New File or Project... -> Applications -> Qt Quick Application -> Qt Quick 2.2

          Click "Run. What do you see?

            It's Angle version , not OpenGL
            About My GPU : (AMD Readon HD 6670) OPENGL 4.1 SUPPORT : Yes
            In Qt Creator I have Qt Quick 2.2
            After create and run this is result : http://persianupload.com/kleeja/do.php?imgf=13994592497651.jpg

              If you still want to use QWidgets, add "QT += widgets" to your untitled26.pro and try QQuickView/QQuickWidget again.

              EDIT: What version of Qt Creator are you using? Your project looks different

                Unfortunately doesn't work ! :( content of QML file is a string ("Hello world") but isn't show.

                See : http://persianupload.com/kleeja/do.php?imgf=139946053737491.jpg

                and my project : http://persianupload.com/kleeja/do.php?filename=139946053748452.zip

                  Your URL is wrong.

                  Look inside main.cpp -- the correct URL is written there.

                    This is main address of qml file : qrc:///qml/main.qml

                    view->setSource(QUrl::fromLocalFile("qrc:///qml/main.qml"));

                    can you check my sample of code ! this is : http://persianupload.com/kleeja/do.php?filename=139946053748452.zip

                      Also, open main.qml and change Window {} to Rectangle {} -- that will make things easier for you.
