I am started to implement the microsoft ribbon interface on the qt library but finally understand that it is too complex task for me.
So I decided to use native mfc ribbon inside my application.
But the main question is how to do this?
Qt does not have native "MFC Ribbon", but the closest thing available is QTabWidget. You can use CSS stylesheets to make it look somewhat like MFC Ribbon. If you want exact look of MFC Ribbon, then you need to reimplement paintEvent and draw the widget as you need.
Some CSS Examples to get you started.

2) http://doc.qt.io/qt-5/stylesheet-examples.html#customizing-qtabwidget-and-qtabbar
There is a pre-built library called QtitanRibbon, although it's not free take a look into the free trial version.

I am working on OpenGL to create a GUI .I want to create some tabs which will help me to display different things in different windows. How is this possible using OpenGL? I read in some articles that we can use QT for that. Since I have already developed some of the GUI part in OpenGL using GLUT library ,is it possible to use the same code in QT? If so brief me how to make settings for OpenGL libraries in QT creator.
In my GUI I am trying to create a Car which is following a track.
I think you might be mixing some things up: OpenGL is a API with which you can instruct drivers to draw visual primitives, like lines, boxes, 3D triangles, pictures from buffer onto a render plane.
GLUT is a library that gives you a minimal environment around that, ie. it handles creating a window etc.
Neither of them are high-level UI description tools. Qt is really most likely what you want, as it will not only give you things like tab widgets etc, but also a feature-rich framework to do things like defining what should happen when you click a button, close a window etc.
There's a lot of examples of OpenGL usage within Qt widgets. In fact, a lot of visualization frontends use Qt and OpenGL. Qt has extensive documentation on how to generate OpenGL contextes and draw inside Qt applications.
I have tried to search on the internet and here as well, without success though. I am using Qt 4.8.2 and design my app in the Designer, then I write code in VS2010. I would like to show a chart on the application window, e.g. like http://www.infocaptor.com/user_help/help_img/dashboard_line_chart_screen.png , based on some data that are created by the app.
In the Widget Box of the Designer, I can't find any widget related to drawing. So I tried creating a QTextEdit and drawing on that using QPainter. However, this does not work. I can draw on the whole appwindow, but not just on the text edit. So the question is: what widget can be added onto the app window in the designer and that is going to allow me to draw on it using QPainter?
I'm eluded as the documentation says specifically that QPainter can draw on any QWidget which a QTextEdit is...
Any help is much appreciated,
Daniel
The function of "drawing" is tooo complex/unspecific to be included as a specialized widget. You'll have to create it yourself and implement the desired drawing functions.
Here is an example which you can learn from, the scribblearea class could be pretty much what you are looking for. In that case you can copy it to your project and use in in the Qt-Designer by promoting a widget to this class.
I'm currently trying to get Qt working with my existing program.
I'm using SFML for creating my OpenGL rendering context and creating the window. The things I tried out so far however always create a separate window by Qt instead of just rendering into the existing context.
Is there any way I can force Qt to render to an already existing OpenGL context?
I've not looked into the specifics, but this has been done for openage.
I think looking at the documentation for QQuickRenderControl might be a good place to start.
Qt wants full control over the windows and the event loop, so this will not work (unless you put a lot of effort into it). Your best bet is using a QGLWidget and emulate the event management of SFML with that, so that your application effectively runs on Qt. It is very well possible to render Qt widgets into a OpenGL window (Qt has a OpenGL widget backend) but this must be still managed by Qt itself.
I have enabled qt+OpenGl+SimpleGl on one of the ARM platform and was able to run opengl example programs.
I also has a qt+Webkit, which is working with a graphic plugin.
I wanted to use simpleGl context for every thing, instead of using the normal graphic screen. So, when I try to run Qt+Webkit with simpleGl, I just get a blank screen.
Does QT support this? If so how can we make it?
Yes, this is correct. OpenGL draws directly to the framebuffer. The simplegl driver doesn't handle what is drawn using the raster paint engine of the QWS, so you may see only black.
Using simplegl for "everything" means you want everything to be drawn using OpenGL in your EGL full-screen window? This is possible under some assumptions. You have to write all your applications to be rendered using the Qt OpenGL paint engine (using the opengl graphics system is not supported under Qt/E). This is possible also for QtWebKit, I'm doing it now. Note that this does not mean that everything is rendered using hardware acceleration. You'll have to write your applications "the right way" to get all actually hardware accelerated. Consider that you'll have to handle the mouse pointer some other way in this case.
The other way is to just modify the simplegl driver to allow for the use of Qt applications using the raster paint engine. This is possible as well with some limitations. Qt can use blit to place its own windows over OpenGL. Look for the framebuffer driver inside the Qt source tree to know how to do this. You can then have common Qt applications and OpenGL Qt applications some way. I'm doing this as well. Not everything can be done anyway.
EDIT: I'm sure you already did, but in case, give this http://doc.qt.io/qt-4.8/qt-embeddedlinux-opengl.html much attention.
Unfortunately I don't know anything about SimpleGL, but I do know that there is a way to render a standard Qt widget in a QGLWidget. Maybe have a look at this Qt Quarterly which I think is somewhat related to your question:

Does Qt support ribbon control?
I want to share with you the link to site has published screenshots of their component Qtitan Ribbon for Qt.
http://www.devmachines.com/qtitanribbon-overview.html
While there is no dedicated Ribbon widget in Qt, you can fashion something similar yourself. You could take a QTabWidget and put some buttons inside (and optionally style it to look a bit more like Microsoft's Ribbon). Depending on what you're trying to accomplish, that might suffice.
One of their sample apps apparently has a ribbon, so it should be do-able.
http://qt.nokia.com/images/products/vtk-designer-opengl-screenshot
You can take any JavaScript/JQuery ribbon, insert it into QWebView and do whatever you want with it, using the Qt Webkit Bridge.
There is no Qt ribbon control.
I believe there are license issues preventing Nokia from developing a ribbon control that is similar to Microsofts.
There are free alternatives to QtitanRibbon by now, for example, checkout:
https://github.com/martijnkoopman/Qt-Ribbon-Widget
You can even directly use it in any *.ui file!
Simply add a QTabWidget in QtDesigner and then promote that widget to the Ribbon class.
No, it doesn't. I didn't find out any plan to support it in the future.
We use QtitanRibbon, and it works very well for us. Support has been good, documentation on the short side. Worth noting that it not only provides a ribbon UI, it also makes it convenient to implement dark mode (or in our case, we opted for grey mode).
