Alt Gr as one key, scancode? |  |

Hello,
I'm working on a game which uses LCTRL and RALT as keybinds which may, and likely will, be used in parallel. Hence the Alt Gr key of some international keyboards (same location as RALT) causes issues on windows, since here this is interpreted as both LCTRL and RALT and not a single key, it seems. Is there any way to recognise Alt Gr as only RALT (or as a single key to redirect in the code) without interfering with LCTRL at the same time? i.e. if holding down Alt Gr, one should still be able to press LCTRL and recognise that in parallel. Would I be using the Alt Gr scancode for this purpose, and would that be reasonably reliable if it was used only for windows, or does it vary wildly with different keyboards anyways? There was some discussion previously regarding this in but it seems inconclusive: http://lists.libsdl.org/htdig.cgi/sdl-libsdl.org/2005-September/051930.html -- Martin Erik Werner _______________________________________________ SDL mailing list http://lists.libsdl.org/listinfo.cgi/sdl-libsdl.org |

Huh? That doesn't look like expected behavior at all, a single key
should only have a single scancode in my opinion. Is there a bug report for this? I'm not part of the SDL team but it's probably worth bringing up to their attention. 2012/11/9 Martin Erik Werner:

I don't know about scancodes, but it's definitely the case that I get two keysyms from it, as the previous mailing list posting from 2005 was noting. Is it true that this is down to how windows handles the key and it's impossible to distinguish it in SDL, or is there a way around it/is it a bug in SDL? -- Martin Erik Werner _______________________________________________ SDL mailing list http://lists.libsdl.org/listinfo.cgi/sdl-libsdl.org |

Welp, was looking around and it seems Windows seems both Ctrl and Alt
key events when AltGr goes down because on several keyboards the right Alt key is missing, so this is used to emulate that instead. The solution would be to use either raw input or DirectInput. Found this, maybe it helps: http://molecularmusings.wordpress.com/2011/09/05/properly-handling-keyboard-input/ 2012/11/9 Martin Erik Werner:
