Hello list folk - I'm trying to print out strings representing various
keyDown events I receive. Using OS 10.6.2.
It looks as though this was possible back in the classic days (
http://developer.apple.com/legacy/mac/library/documentation/mac/Toolbox/Toolbox-78.html
), however obviously that doesn't do much for me here.
Obviously the characters / charactersIgnoringModifiers strings I get
with the event works great for alphanumeric stuff, however I'm also
interested in things like function keys & the like. And up to this point
I'm afraid that all I've been able to find on this makes me think I'm
going to have hard-code a lookup table to translate non-alphanumeric key
presses, which has me freaked out, since I've no idea what keyboards are
like in other locales.
So far the two approaches I've seen are as follows:
Approach #1: Map every keyCode you can think of (example: the
keyStringForKeyCode method in
http://ritter.ist.psu.edu/projects/RUI/macosx/rui.c ) :
switch (keyCode) {
case 0: return("a");
case 1: return("s");
...
case 96: return("F5");
...
Approach #2: Get what you can via UCKeyTranslate, and then 'fill in the
blanks' with a lookup table for non-alphanumeric stuff (example:
http://inquisitivecocoa.com/2009/04/05/key-code-translator , which looks
like it builds off a patched version of
http://rogueamoeba.com/sources/HotKeysLib3.zip )
Prior threads by people in the know (
http://www.cocoabuilder.com/archive/cocoa/101991-key-codes-and-characters-in-nsevents.html
) further state that developer-created lookups are a fact of life in
this area, but I'm reely hoping they are not ...
Questions:
1) Is there a programmatic method to get strings like this (I'm
guessing not)
2) Is a F1 key the same on all keyboards (if so then my worries
about the lookup table are a non-issue)
3) Are there any keys typical in other places that don't exist on a
'standard' North American keyboard ? (if so heaven help me)
Thanks all for any insight you may be able to provide - Dave
