Hi everybody. I've started playing with allegro for a few days now, and i must say i enjoyed it, even if i had to spend 10 hours to build the frameworks and everything ^^ I have done a little program for fun, but i can't get it to work in fullscreen mode. Here is my code : 1#include <iostream>
2#include <allegro5/allegro.h>
3#include "allegro5/allegro_image.h"
4#include "allegro5/allegro_opengl.h"
5#include "allegro5/allegro_audio.h"
6#include "allegro5/allegro_acodec.h"

And here is the error i get : 2012-06-26 22:27:43.111 Allegro Project[40388:6607] invalid fullscreen drawable 1280x800 is my native screen resolution, so i really don't understand why it doesn't work Thanks for reading this, i hope someone has fixes this and can tell me how to do it |

Yes, both fullscreen as well as fullscreen-window are broken right now (under OSX 10.7). The SVN version has a fullscreen-icon on all resizable windows which you can use to switch to fullscreen - it's the only working way for now. I have investigating whether that can be used to fix fullscreen-window (by automatically triggering it somehow) on my todo list, but might be a while so hopefully someone beats me to it. -- |

I'm glad i made you remember this, i'm going to try to build the svn source then, just to try fullscreen more because it's so much more fun with it ^^ And thanks for your quick answer, i won't spend the night trying to figure this out then |
