OK, more background needed. I develop the TextTest tool which is a generic test tool that starts tested applications from the command line. The idea is that it can handle any system under test at all, whatever language it's written in. Preferably without requiring a bunch of changes to the tested code before starting. I'd like to be able to pass some sort of flag to ensure that the system under test *and everything it starts* remain hidden.
I can do as you suggest in my PyGTK GUI, of course, but that's only one system under test. A generic solution, if there is one, would be much better. I felt like there ought to be one because : a) It's easy on UNIX and b) I managed to hide the system under test fairly easily, just not its child windows and dialogs. Thanks for the help, anyway, it's another fallback if I can't find a solution. -- http://mail.python.org/mailman/listinfo/python-list
