Re: Multiple Selection in NSComboBoxCell

Abhijeet,

I'm replying to you in private as well as to the list.  I developed on =
Mac OS X and before that YellowBox (NeXT-derived precursor to Cocoa that =
ran on Windows NT) in the late 1990s and early 2000s.  You were very =
clear in your question.

I don't have an answer to doing exactly what you intend here, since I =
haven't programmed in Cocoa for some time, and the API has been =
upgraded.  You could probably do something with the NSControl or NSView =
that forms the NSItem in the combo box, to put NSSwitch (a checkbox) in =
that NSView.  NSView is flexible and opens up the entire domain of what =
you can put just about anywhere on the display.  So if you can get to an =
NSView that is part of the combo box item you can obtain multiple =
selections that way.  That's the principle I would use as you research =
the API documentation.  I likely have some details wrong here, but as I =
recall from my programming, the combo box or popup is made up of =
multiple NSItem or some such, and you may be able to access the NSView =
for this item.  Then you can nest.  I can't check the API currently, and =
I'll research this myself later.

If that doesn't work for you, I would consider re-factoring the UI for =
that NSTableView and its parent NSWindow.  What I would do is to put the =
NSTableView at the top of the NSWindow and put detail controls for data =
entry in ***form view*** below the NSTableView.  That is, the user would =
select a row in the NSTableView (which would not be editable) and then =
the user would data-enter the values in fields below, on a form layout, =
using standard controls.  For a combo-box type entry with intended =
multiple selections, you could use another NSTableView instead.

I hope this helps!  Feel free to let me know if I'm not clear, or if =
this does in fact help to clarify.  And, of course, you may have gotten =
clarification already.
