I'm building a custom view
1) What is the recommended way of raising external "events" (at least
that's what they were called in C#) from within a custom view, in
order to trigger actions in other objects that may be observing the
view? I assume it is to use a delegate outlet, right?
However I noticed that not all views use delegates to trigger external
actions. For example, NSButton don't seem to have a delegate, but they
have the "Sent Actions" section in the menu that appears on Ctrl+click
in the IB, that is initially empty ("selector"), but filled with sent
actions, as I connect the button to other objects. I am confused about
what exact button's event is supposed to trigger those "sent actions"?
Isn't it that even a button can have multiple events, e.g. click,
mouse dragged, mouse roll over etc.? Or is there a "default" event,
like "click", that is used for the sent action?
2) I have found that IB automatically treats all member variables of
my custom view's class that are of type "id" or "id<...>" as outlets,
i.e. they appear in the list of outlets on Ctrl+click. This is not
always desirable. How do I prevent some of those variables from being
treated like outlets?
Thanks!
