Hi all,
In my last post I mentioned that the qt.conf INI file was key to
fixing the "cannot move to target thread" problem, caused by multiple
instances of Qt running in the same app. The following setup.py file
is my encapsulation of the solution. This is my first brush with
py2app, so there may well be some idiosyncrasies in my code. I'll
look into contributing a recipe when more of the dust settles.
Thanks
Scott
