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)

QT += core gui qml quick declarative[/quote]Remove "declarative". That is for Qt Quick 1 only.

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

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

[quote author="Kamb!z" date="1399462538"]view->setSource(QUrl::fromLocalFile("qrc:///qml/main.qml"));[/quote]You shouldn't use QUrl::fromLocalFile(), because items in QRC files are not local files. See main.cpp for the correct way of calling QUrl.

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

Not working for me again ! Can you give me a sample ? please !
I want to compare your project with mine.

@
// mainwindow.cpp
// Change this...
QUrl::fromLocalFile("qrc:///qml/main.qml")

// ...to this:
QUrl(QStringLiteral("qrc:///qml/main.qml"))

@
// main.qml
// Change this...
Window {
