target/action
Is this the same as the following?
action is sent to target on a click. The other things you mention
are either
not detected or not sent on to the target.
I don't quite understand how target/action works under the hood. If I
were an implementor of NSButton, how would I declare that namely the
"click" event should trigger the actions in the Sent Actions list?
Currently the "Sent Actions" section does not even appear in my custom
view's connections menu at all, how would I make it appear?
Yes, it's the same, though usually target/action is used with standard
controls and probably wouldn't be used for general signalling from a
custom view unless you are doing something very control-like (in which
case you could inherit from NSControl and get this support for free).
programmatically, you use -setTarget: and -setAction:
in IB, you ctrl-drag from the button to the target, and pick the
action from the popup menu. This can then be reviewed in the "sent
actions" section of the button's attributes under the "connections" tab.
