Hi,
Hopefully this is a simple one:
I have an NSTableView, one column of which uses NSPopUpButtonCell and has its
content bound to one NSArrayController which controls an array of list item
strings for selection. Its selectedIndex is bound to the property of a
different array controller. The actual index that gets loaded in may be beyond
the number of items in the list array (as it may previously have been
associated with a different list). In this case, the table view just shows an
empty cell.
This is okay, but what I'd really like is to set a default selection index in
this case. i.e. If the selectedIndex of the object >= [popupListArray count],
then set it to select the last (or first) item (i.e. so that internally it is
doing something like, if (selectedIndex >= [popupListArray count]) {
selectedIndex = [popupListArray count]-1; } ). I thought I might be able to do
this automatically using the "No selection" or "Not applicable" placeholder,
but it turns out that it doesn't quite work like that. Is there a way of
setting this up automatically, or near-to-automatically?
Many thanks in advance,
Keith
