Given that openbox does not include the capability of obtaining a screenshot,
I've written a little routine in python to accomplish that task. I'm running
Fedora 13, and am trying to strip down my installation while still making it as
complete (for my needs) as possible. The code (shown below) seems to work
properly, but when I run the program from a terminal and select the --screen
option, I get the following error:
(screenshooter2.py:4787): Gtk-WARNING **: Missing argument for --screen
Can anyone explain why the error occurs?
TIA
