Which OS are you using? Under any 32-bit Linux I have access RAND_MAX is 2^32 - 1.

You can write ogl es 2.0 compliant OpenGL code on desktop using GLEW for instance. Then again I dont use windows to do so, on Linux I just install the glew packages from apt and compile away.

Ok, well, I am personally more into C++ side, and have made just a few simple projects in QML, so I might not be the best guy to ask. But for mobile, QML is definitely a great choice - very flexible, very (and here I mean really, REALLY very) easy to learn, and yet quite powerful. About the viewer - again, it's just one of a few options, and there will be major changes here in Qt5. For the time being, let's focus on Qt4. You can use QML viewer to run plain QML/Js projects. So, it's not a necessity, more a convenience helper. You can easily create your own app without the viewer, simply use QtDeclarative module - the widget that displays QML is called QDeclarativeView, IIRC. It also gives you additional benefit of C++ - you can easily code a "mixed" app, where some parts are done by QML, even by some graphic designers with no programming skills, while coders make the C++/ JavaScript backend.

Well ,currently can get it working with inline string typed shaders.shader files somehow don't get loaded.Also I see that the best thing is to use native (non Gt wrappers) OpenGL libs

gDEBugger showed that after a while the texture object in memory exists, but its size is zero

I've tried to use some files from the DirectX SDK with MinGW with no luck. Please keep in mind that I had no luck - there is possibly a way I do not know of.

Hi, Check about QGraphicsPixmapItem and QPixmap classes, it should be a good begin!

System events (what mouse and keyboard are typically) are send in a different way: sendSpontanousEvent, which is an internal Qt method. I'm not 100% sure, if that can be achieved the way you try to do it...

Be sure and edit your post title to add [Solved] at the beginning. Thanks!

thanks that trick work for QGLWidget also.. Thank you..

Hi Tratstil, Can you please share some more details about how you solve the problem. I am also using Phonon in one of my project. But when I change volume using volume key it dose not affect volume to Phonon AudioObject. You said you set application name and it solve your problem ? Are you referring to QCoreApplication::setApplicationName ? Thanks, Kunal

What is indielib doing?

This link should place you directly on the page: http://harmattan-dev.nokia.com/docs/library/html/libqtgameopengles2/main.html?tab=1 The trick is to copy the URL by right-clicking the link pointing to it in the navigation. I know, not the most usable way.

thanks very muxh. I got it :)

Alright, bug report posted "here":https://bugreports.qt.nokia.com/browse/QTCOMPONENTS-1074

this information we have been helpful thank you!

I think I got you.You mean packing different data for the vertex buffer in a single vertex array.Like vertices positions,color, like : @ GLfloat vertAndColors[]={ 23.0f,12.0f,23.43f,/vertex 1 /0.23f,0.75f,1.0f.1.0f / RGBA color for that vertex/ , .... ...... ........ } @ ?

Since I am using SFML 2 this is a deprecated function so I cannot use it, but I have used it's equivalent - Save/Restore GLStates but to no avail.
