Window / Re: SFML 2.0 RC, OpenGL 3.3 and Window.display()

Instead of applying your idea to Window.cpp, I slowly changed the tutorial code until things... just worked!
That means I must have made a mistake while transcribing the tutorial code. 

For people interested in seeing http://en.wikibooks.org/wiki/OpenGL_Programming/Modern_OpenGL_Introduction work with SFML, check out the working version here: http://pastebin.com/xnTzaW96

Pretty amazing how it only takes one line of code to get a working opengl render context in SFML Thanks!

Window / [Solved] SFML 2.0 RC, OpenGL 3.3 and Window.display()

« on: September 26, 2012, 08:37:12 am »

I started following this tutorial on http://en.wikibooks.org/wiki/OpenGL_Programming/Modern_OpenGL_Introduction but instead of using GLUT I decided on using SFML 2.0 RC. The goal is to draw a simple triangle in 2D.

The full source of the tutorial is here:
https://gitorious.org/wikibooks-opengl/modern-tutorials/blobs/master/tut01_intro/triangle.cpp
My code using SFML 2.0 RC is here:
http://pastebin.com/ucunPzL3

If you look at the tutorial code on line 105 you'll see a call to glutSwapBuffers() at the end of the onDisplay() function.
Since I'm not using GLUT, I figured this should be App.display() (where App is of type sf::Window).
So I placed App.display() after the call to onDisplay() in the main loop, but that doesn't show any triangle.
I also tried passing sf::Window App to the onDisplay() function with a pointer, and calling App->display() at the end, and inside onDisplay() but that didn't show a triangle either.

The tutorial code works fine on my system when compiling with
g++ -o main main.cpp -lglut -lGLEW -lGL
And my code is compiled (without glut) using:
g++ -o main main.cpp -lsfml-window -lsfml-system -lGLEW -lGL

What's the best way to replace glutSwapBuffers()  ?
