I have a follow up question.
One of the columns in the table shows a number (a float), and I have added a min and max value property to my controller to filter the data in the table. I could filter the data every time the user changes the min and/or max values but that means I need to recreate the data every time which is not very efficient. So bindings to the rescue, I thought.
However, NSTableColumn does not have min/max bindings to use. I tried adding an NSNumberFormatter to the column, but there are no min/max bindings for that as well.
Is there a way to do this?
- Koen.
