Title: Keyboard.IsKeyPressed: How to detect 'dead' keys?
Post by: Gonzilla on June 12, 2012, 04:00:33 pm

How can I detect if the user press the circumflex-key [^]?

When I press the [^]-Key I got following Code:
{[KeyEventArgs] Code(BackSlash) Alt(False) Control(False) Shift(False) System(False)}

The other dead keys like the ´ (LBrackets) and ` (RBrackets) working fine.

Why do you want to detect these keys?

Unfortunatly SFML isn't able to detect all possible key combinations with all the diffrent keyboard layouts.

I guess you'll have to find another way if you need to use the [^] key.

Additionally it could be helpfull if you'd tell us which keyboard layout you're using.

@Laurent:
In many games you can show a game console with that key. I would like to have a such functionality in my game too.

@eXpl0it3r:
I use the QWERTZ / german layout.

But I see "the problem":
http://en.wikipedia.org/wiki/Keyboard_layout#United_States (http://en.wikipedia.org/wiki/Keyboard_layout#United_States) the key is tilde
http://en.wikipedia.org/wiki/Keyboard_layout#Austria_and_Germany (http://en.wikipedia.org/wiki/Keyboard_layout#Austria_and_Germany) the key is circumflex

This explaine why it work with some games, but how they are "transforming" the keys that they work with us and german layout?

Keyboard layouts are indeed not handled perfectly.

Ah okay, already reported  ;) Maybe this article help you with this problem http://www.luminance.org/blog/gruedorf/2009/08/14/supporting-alternate-keyboard-layouts-in-xna-games (http://www.luminance.org/blog/gruedorf/2009/08/14/supporting-alternate-keyboard-layouts-in-xna-games). Although it is about XNA but maybe it helps.
