Can someone direct me to a downloadable NSComboBoxCell example?
I've been looking for one on google but I can't find any that I
understand or that is downloadable. For example this one here: http://
www.cocoadev.com/index.pl?NSComboBoxCellExample
It's not downloadable. I could spend maybe a few hours trying to put
this together, only to find I did it wrong or that maybe it doesn't
demonstrate what I need, at which point I must look for a different
example and those hours are wasted.
And this, I totally don't get:
-(id)tableView:(NSTableView*)tableView objectValueForTableColumn:
(NSTableColumn*)tableColumn row:(int)index
{
return [[records objectAtIndex:index] objectForKey:[tableColumn
identifier]];
}
When you are using NSComboBoxCell, your table is now a 3D table! You
have the row, column, and combobox selection as the indexes. So how
is this code working then?
Don't tell me that NSComboBoxCell is being treated as a plain old
string? If that is the case, then the I need to modify the behaviour.
This is because for some (but not all) rows, I want the combobox to
not allow arbitrary text to be entered, only allowing the values that
are in the combo's list.
But for other rows, I want the user to be able to enter arbitrary
text, even if it's not listed in the combo's list.
So then this really makes the table a 3d table. Do I need to look up
the value of the string in objectValueForTableColumn, within the
array of strings I have for that particular cell, to get the third
index?
Thanks if you can help!
