Draw more than one triangle strip using index buffer and drawElements?

[akilone]

Is it possible to draw more than one triangle strip using drawElements with vertex indices stored in indexBuffer?
I found that in OpenGL is possible to split indices in triangle strips with glPrimitiveRestart function. How the same thing can be done in Qt OpenGL? Is there a way to split indices in indexBuffer and to draw more than one triangle strip using drawElements function?
