[Pyobjc-dev] Blocks support in PyObjC

[Vladimir P. <far...@gm...>]

Hi all,

Does PyObjC support selectors with block arguments? I'm trying to make
use of NSOpenPanel's beginSheetModalForWindow_completionHandler_, but
I'm somewhat unsure what to pass as the second argument. I've tried
creating a callback function like this:

def doneImport_(res):
    print "panel","returned",res

But I'm getting <type 'exceptions.TypeError'>: Argument 3 is a block,
but no signature available

Wrapping the function with @objc.signature('vI') doesn't help either. Any hints?
