I think the problem is that context is created but not associated with current thread.

Try with ExecuteGL method...

Hello Mirek, you are right, doing this kind of thing work :

void GLCtrl::GLPane::ExecuteGL(HDC hDC, Event<> paint, bool swap_buffers)
{
	static bool HaveBeenInitialised = false;
	wglMakeCurrent(hDC, s_openGLContext);
	if(!HaveBeenInitialised){
		static_cast<GLCtrl*>(parent)->Initialisation();//--> I call Initialisation Here
		HaveBeenInitialised = true;
	}
	paint();
	if(swap_buffers)
		SwapBuffers(hDC);
	else
		glFlush();
	wglMakeCurrent(NULL, NULL);
	
}

That said, doing this in GLPaint actually seems fine to me.

Yes, it work aswell but the idea of having a visible boolean just to do some action at the first loop of drawing is disturbing me Twisted Evil

(the fix I did in ExecuteGL(...) is basicly the same things but user don't see it Very Happy

Is it possible to add it to the GLCtrl code or you prefer stay like that ?

Thanks in advance
Best regard !
