Problem

On Windows systems using Autodesk Maya, the text input field of the Script Editor doesn't regain focus after having restored focus to the main window. This event handler explicitly restores focus, if it turns out to have been the last active panel at the time of leaving the application.

Usage

Place the full contents of the script below into your userSetup.py and never again lose focus.

How to recover lost Python source code if it's still resident in-memory

I screwed up using git ("git checkout --" on the wrong file) and managed to delete the code I had just written... but it was still running in a process in a docker container. Here's how I got it back, using https://pypi.python.org/pypi/pyrasite/ and https://pypi.python.org/pypi/uncompyle6

Attach a shell to the docker container

Install GDB (needed by pyrasite)

apt-get update && apt-get install gdb
