Where to find materials about Qopengl?
Does Qopengl perform as well as glew?
Cant manage to find way to draw lines, google has not much to offer.
glColor3f( 1.0f, 1.0f, 1.0f);
// Draw a triangle:
glBegin(GL_TRIANGLES); // Lower left vertex
glVertex3f(-1.0f, -0.5f, -4.0f); // Lower right vertex
glVertex3f( 10000.0f, -0.5f, -4.0f); // Upper vertex
glVertex3f( 0.0f, 0.5f, -4.0f); glEnd();
Hi and welcome to devnet,

Tested code into that example replacing part that draws traingle with code above but it wont work this way
It wasn't meant to be just copy/replace. The example shows how to do it (the triangle part) using a recent version of OpenGL. You are using the old fixed pipeline with your functions calls.
Thanks for your knowledge, will look into newer opengl documentation.
