[Pyobjc-dev] method swizzing

[Daniel A. <an...@cc...>]

I'm trying to make my program log every event that happens. I'm  
probably doing it wrong. What I'm trying is:

oldIMP = NSResponder.instanceMethodForSelector_('mouseDown:')
newIMP = objc.selector(lambda self, e: NSLog('%s: %s'%(self,e)),
            selector=oldIMP.selector, signature=oldIMP.signature)
objc.classAddMethod(NSResponder, 'mouseDown:', newIMP)

This works great - but only for clicking in places on the window that  
don't already do anything. When I click on a NSButton, for example, I  
don't get anything logged.

I can go through and do the above for every subclass of NSResponder in  
my program, but that gets a little bit pesky, especially because it  
looks like I'd have to separately do it for things like the headers of  
NSTableViews and so forth.

Is there a better way?
