This was a mighty useful advice. The internet doesn't seem to be aware
of this
solution (as mentioned, I only found the clue to pack things together
via
py2app). Is there a possibility to make this more prominent in the
docs or add a
page with Mac OS X notes to some wiki?
Cheers,

Given it's a Mac-only problem, which wasn't reproducible with Qt, only
PyQt, for me it looks like a PyQt bug. But the fix is quite easy.

Hi,
Every pyqt example I start under Mac OS X (PyQt 4.5.4, Python 2.6
from
Python.org, Mac OS X 10.5.8), no matter which (I tried the delivered
examples
in the source distribution and also the examples from the python
book [1], I
also tried the eric IDE and spyder) fail to receive the focus when
launched.
A click is needed to raise the application. Sometimes the newly
opened
window
is hidden under others.
I am aware that I have to use pythonw (instead of python) for GUI
scripts,
but
this doesn't change anything. After googling I read that I just
have to
bundle
my scripts in .app packages because the issues is all Apples fault.
I feel
this is
unelegant and most importantly: all wxpython applications RECEIVE
the focus
when launched (no matter if with python or pythonw), therefore
there IS a
way
to make scripts open up GUI applications with focus. I give code
examples
for
pyqt (no focus) and WXPython (receives focus) below my message.
Maybe someone with more insight can shed some light on this problem.
