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.
