On OSX the pgzero window doesn't get focus.

This appears to be caused by https://bitbucket.org/pygame/pygame/issue/203/window-does-not-get-focus-on-os-x-with

Further investigation shows that the problem is only when inside a virtualenv, though SDL2 works inside virtualenv. SDL2 is also a bit snappier than SDL, ~1 second load time vs ~6 seconds.

All examples works OK, except music.py (I'm missing a codec) and ptext.py. The tracebacks follows:

music.py (fails for both SDL and SDL2)

I'll leave it with this, as pgzero actually works as described if following the installation manual. My bad on the virtualenv.

Yes, that was what I was thinking.

What about this?

try:
    import pygame_sdl2
    pygame_sdl2.import_as_pygame()
except ImportError:
    pass

EDIT: in runner.py

Great news. Could you verify that all the examples work and do a pull request to add this as an extra section to the installation docs? If it's possible to install without virtualenv, even with some bootstrap in pgzero.runner, that would be even better. Or just as simple as you can make it.

Using pygame sdl2 works!

brew install python3 sdl2 sdl2_gfx sdl2_image sdl2_mixer sdl2_ttf
mkvirtualenv -p /usr/local/bin/python3 pygame_sdl2
pip install cython
git clone https://github.com/renpy/pygame_sdl2
cd pygame_sdl2/
python fix_virtualenv.py
pip install .
cd ..
hg clone https://bitbucket.org/lordmauve/pgzero
cd pgzero
wget https://gist.github.com/arve0/c1be371566a9099747a4/raw/3227645c10b28241b50ab35b1cc7006036ff391c/runner.py -O pgzero/runner.py
pip install .
wget https://gist.github.com/arve0/a22efe8f591610799ba6/raw/c61d4895afc87d9a304f83467db90e46cd97cbba/hangman.py
pgzrun hangman.py

Adding, pygame is not found in the open programs (Alt-Tab):

Here is what is expected (python 2):

Here is some debug info.

Code to reproduce is found here.

A more detailed description in images:

1. pgzrun hangman_solution.py - opens pygame in background window:

2. Focus pygame with mouse - brings window to front, but menubar shows "Terminal".

3. Press abc characters - characters echoed in terminal, pygame is unaffected (see picture above).

@funkyhat Have you found a work around? A "fix" was proposed in pull request #13, but it was declined, as python 2 support is not wanted.
