[Pyobjc-dev] Performing selectors example?

[James T. <tra...@gm...>]

Hi,

I'm trying to get performSelectorOnMainThread working in PyObjC, based
on an example found on the site:

http://pyobjc.sourceforge.net/documentation/pyobjc-framework-Cocoa/threading-helpers.html

However, I've been unsuccessful in my attempts to receive the
callback. Can anyone point me to a working example of this
functionality?


----------

class MyClass (Foundation.NSObject):
    def callback(self, arg):
        print "Test!"
    def setup(self, arg):
        self.pyobjc_performSelectorOnMainThread_withObject_('test', 44)



 dl = MyClass.alloc().init()
 setup("arg")


--> [MyClass pyobjc_performOnThreadWithResult:]: unrecognized selector
sent to instance ...

Well, you are trying to call a 'test' selector which clearly does not  
exist, hence the 'unrecognized selector'.

You probably want:

self.pyobjc_performSelectorOnMainThread_withObject_('callback', 44)
