Shiny!
Finding out the hard way was good for getting the hang of how it works, but knowing that there's a hasslefree way to do it made my day...

Thanks a lot, Venemo!

From a user's point of view, I'd advise against unclosable progress bars.

In maemo, that thing will completely take away the ability to close that application, so in case anything goes wrong with either your C++ code or your shell script, the user is stuck with an unclosable application until they either reboot or manage to issue a successful kill command (which, btw, didn't work for me - the application was completely locked).

Instead, issue a warning in your progress bar that this might take a couple of minutes and should not be canceled. Warn the user, but don't take away control over their own system.
