PyQT vs PyObjc / Cocoa-Python

Question

I'm thinking about developing an app for OS X using Python. I don't know Objective C and don't want to learn it right now.

I know and like Python. I'm trying to determine what GUI toolkit to use. I already have a bit of experience with PyQT, but not much. I've also seen that PyObjc or Cocoa-Python seem to allow use of Cocoa UI components from Python.

I'm curious if anyone has any input on how PyObjC stacks up to PyQT. I would be giving up cross platform abilities and I am not sure what I would be gaining.

I'm leaning towards PyQT right now, but wanted to see what you all thought. My big dislike of PyQT is having to pass around strings for the signals and slots. Is PyObjC similar?

Answer 1

If the only thing stopping you using PyQt is passing strings in signals, then the latest syntax should make your choice much easier. The old syntax (which can still be used) looks like this:

self.connect(self.action, SIGNAL('triggered()'), self.handler)

But the new style signals are much more pythonic:

self.action.triggered.connect(self.handler)
