accept (s)

An inspector for the menu item "accept (s)" reveals a selector of "#perform:orSendTo:" which is implemented in Browser.

I want to follow the code and I put a halt in "#perform:orSendTo:" but the debugger never opened. What gives?

Hi Dan,

That doesn't sound quite right.

#perform:orSendTo: is probably overridden in Browser, but... have you looked to see if there's an implementation of it on Object or maybe ProtoObject or something like that?

I'm pretty sure that #perform: and cousins are usually general.

Not sure (on a cellphone) without looking at an actual running system, but try looking up the inheritance chain for another implementation of the same selector. That might help.

Let me know either way, when I get back to a real computer I'll look into it for you if you don't get it figured out by then.

Good hunting!

Casey

I didn't really say that well. If you're modifying a method and don't observe a change in behavior, it could be that you've changed a method that's overridden in a subclass, and that subclass may be the template for the actual object that's in play.

The reason I said to look up the class hierarchy was basically to ask you to check whether or not this is a method which runs deeper than just Browser.

Does that make sense?

Anyway let me know what you run into.

Is it? In my image, Browser inherits that method from StringHolder. I checked using a protocol browser (which shows all messages an object understands, including those implemented by superclasses).

I want to follow the code and I put a halt in "#perform:orSendTo:" but the debugger never opened. What gives?

When I put a halt in StringHolder>>perform:orSendTo:, the debugger opens fine, but only when I use the menu item to accept. The keyboard event uses a different code path.
