Re: [Pyobjc-dev] PyObjC CGPoint error in CGEventCreateMouseEvent

[Ratko J. <rja...@gm...>]

I ran across the same problem back in September and there were a few bugs in
the C code. I reported the bugs and they were fixed so I guess the Macports
version includes those fixes. Don't know about the version numbers.
CGEventTapCreate should take 6 parameters, as it does in carbon.


What do you mean by "breaks the location"?
"*When I run Python26 and PyObjC from Macports the event system works fine,
but making an event breaks the location.*"
