Re: Editing text inside a grid

Text fields in general don't trigger program action until the user
indicates he's done with the field by tabbing out. This saves resources
and simplifies the UI, but makes for a headache in cases such as you
mention, where it doesn't make sense to the user to "tab out" of the
last field he edits.

The outline of the solution is this: Register as an observer for the
NSControlTextDidChangeNotification from your table. In the notification
code...

- (void) textDidChangeNotice: (NSNotification *) aNotice
{
   NSDictionary *    userInfo = [aNotice userInfo];
   NSTextView *    fieldEditor = [userInfo objectForKey: @"NSFieldEditor"];
   NSString *    currentString = [[[fieldEditor string] copy] autorelease];
/* ... */
}
... currentString is the current value of the text in the cell being
edited. I make a copy because the original is the active character
store of the table's text editor.
