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.

I am unable to catch the text written inside the grid ( NSTableView )
without tabbing out. Unless I tab out, the text is not being picked up in
my variable (i.e. the variable is not being set ). Is this some known issue
or do we have a workaround for the same ?

I am using NSTextFieldCell to capture the text entered in the grid.

Any help would be appreciated,
Prashanth.
