I noticed a strange behavior. Including the HotCocoa::Behaviors module in subclasses indeed seem to merge the appropriate custom methods.
class MyButton < NSButton; include HotCocoa::Behaviors; end => MyButton b = MyButton.new => 0 b.on_action {} => 0
But extending an existing object does not work in the same way.
b2 = NSButton.new => #<NSButton:0x800523420> b2.extend HotCocoa::Behaviors => #<NSButton:0x800523420> b2.on_action {} NoMethodError: undefined method `on_action' for #<NSButton:0x800523420> from (irb):12 from /usr/local/bin/macirb:12:in `<main>'

That HotCocoa::Behaviors was what you were missing.

Hi Ben, thanks for your answer.
I tried that initially, but my subclass was having problems being added to the layout view.
Anyway - somehow I got something going a little further - the important thing was to have a create method which has : alloc.initWithFrame([0, 0, *GameSize]) in my NSView subclass...
I did not get much further than painting black (transparency etc did not work) - but its on the back burner while I experiment a bit more with plain MacRuby.
Cheers and thanks, John

I am sure there is an easy answer to this question, but I have not figured it out after some experimenting (nor can I find an example in the examples)
What do I do if i want to subclass (say) an NSView ? And yet still employ that subclass with all the rest of the hot cocoa magic? (so without using nib/xibs)
I would do this to overwrite the drawRect callback for NSView for example - perhaps to do some animation.
class MyView < NSView def drawRect(r)
end end
or, even better in some cases
a = view(:something) class << a def drawRect(r)
end end
