Question

OpenGL

Is the Opengl,Qt syntax translated initially to WinApi syntax? (and then compiling WinApi code).

Answer 1

Err... OpenGL itself, of course it has one and a half calls to create a context, but everything else is the prerogative of the driver.
Qt is of course implemented on top of WinAPI (and draws via OpenGL).

Answer 2

WinAPI in modern Qt, if used, is only used to catch window events. Everything else is mine (I'm only talking about the GUI).
