OpengGL Shader Program fails

[sasmaster]

I can see you didn't define the format and it actually works ?Another question ,are those inclosed GLEW headers and sources used in your program?

By format you mean 'window framebuffer pixel format'?

Yes, it's using GLEW, since there are glGenBuffers, glBindBuffers, glBufferData, glVertexAttribPointer etc.

But why haven't you used the Qt version of those methods?
By Format I mean the QGLFormat.

You mean QGLBuffer. Well at that time there was no QGLBuffer.

It uses default format. I don't see why would I need a fancy format for that code. :)

What's the motivation to use QGLShaderProgram anyway instead of standard OpenGL for portability?

An idea (maybe wrong...) : Implementation of openGL is platform (hardware) dependent. So I guess it could permit an universal call through various platforms or OpenGL revision (and avoid use of OGL extension which I used to add on mac OS platform for exemple).
Nervertheless I prefer use pure OpenGL functions call as long as OGL 4.0 (and so OGL ES 2.0) will not be supported anywhere...

minimoog77 .Getting can't open the shader files errors when running your demo.Do you know what can be the problem?

@
QGLShader: Unable to open file "/vert1.vert"
""
QGLShader: Unable to open file "simple.frag"

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
