Distinguish Pending Text from Committed Text
When using an non-English input method, such as Japanese or Chinese, the entered characters are first in a pending status (i.e. with an underscore). Pressing the space key make those pending text converted to the actual non-English characters. Pressing the Enter key make the underscore beneath the letters disappear. Either way, the pending text become committed. I want to programmatically distinguish the committed text from the pending one, in a NSTextField. [NSTextField stringValue] returns the sum, not only the committed part. Is there any way to do so? ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

NSTextView conforms to that protocol, so if you get the field editor from your NSTextField, you can use those methods. I believe that marked is what that protocol calls what you are referring to as pending, but I'm not 100% sure. (Warning: I've never tried any of this.)

Re: Distinguish Pending Text from Committed Text
You can use the markedRange method and then remove it from the text range you are dealing with to get only the committed text.

Re: Distinguish Pending Text from Committed Text
Thanks Michael and Gideon's reply. [NSTextInput markedRange] works. A minor question is that [NSWindow fieldEditor] returns an NSText*, rather than an NSTextView*. I think that's because of historical reason and it should be safe to always cast a returned NSText point to an NSTextView. Is it safe? 2009/5/20 Michael Ash michael@gmail.com: On Tue, May 19, 2009 at 9:48 AM, Dong Feng middle.fengd...@gmail.com wrote: When using an non-English input method, such as Japanese or Chinese, the entered characters are first in a pending status (i.e. with an underscore).

I don't know if it's safe 100% of the time, but if you do it, drop an assert in your code for sanity's sake: NSAssert( [returnedFieldEditor isKindOfClass:[NSTextView class]] == YES, @Field editor is, in fact, an NSTextView. ); -- Gwynne, Daughter of the Code This whole world is an asylum for the incurable. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
