Re: force NSTextField to accept only Roman, or the other character codes

Hi Norio,

So when the cursor comes to the text field, I want input method to change suitable characters depending on the text field.
Not using validation after user types something in it.

There's no Cocoa API for switching the keyboard/input method. However, on Leopard you can use Text Input Source services to do what you want:

http://developer.apple.com/documentation/TextFonts/Reference/ TextInputSourcesReference/Reference/reference.html

It's works very nicely. On Tiger and under you're stuck with Keyboard Layout services:

http://developer.apple.com/documentation/Carbon/Reference/ KeyboardLayoutServices/DeprecationAppendix/AppendixADeprecatedAPI.html

Which, in my opinion, is buggy and incomplete.
