My application have a search field and a table. When a user types
something in the search field, the table should update based on the
search value.
I solved this by adding the window controller as an observer of the
NSControlTextDidChangeNotification message. This works great. But the
window also have two other fields, and the
NSControlTextDidChangeNotification message is posted also when these
fields are edited.
To solve this side effect, it would be nice to have the text field send
an action when the text in its field changes. As I have understood from
the documentation, the default is that an action message is sent when
the return key is pressed.
So how do I change this? I read the docs for NSControl, NSActionCell and
NSCell without finding the answer to this.
