It seems that InterfaceBuilder won't let me wire up my custom control to send an action to itself. This suggests to me that I am going the wrong way about what I am trying to do, or missing something really obvious. Can anybody advise?
My window has a number of text fields. One represents the current position of an attached translation stage, and other represent limits on its motion. I have a "set" button next to the limit fields which cause them to set their value to the current position of the stage. I think the tidiest way of coding this is to have a custom button class with outlets connecting it to the source and destination text fields, which when clicked executes something like:
[dest takeIntValueFrom:src];
I don't think I can do this purely within IB, without a custom class, since I want the target control to take its value from a third control, not from the sender [the button]. However, ridiculous as it seems, I can't actually work out the right way of executing an action defined in the button itself when it is clicked. IB won't let me wire up an action to itself(*).
How can I go about executing an action defined in the button class itself? (Or why am I going about this the wrong way?).
Thanks for any suggestions
Jonny
(*) actually, I swear I did manage to wire this up once, but I can't get it to happen again. Now when I try to do it, I can drag from Sent Actions/selector to any other object, but not to the sending button.
