Hi!
What’s the best way of dealing with progressbars? I am currently
using a Gtk.idle_add function for updating a progressbar from a
different thread. It doesn’t run very well. I was wondering if
anyone has a better solution to this.

AFAIK, it’s the best way.
Do you have an example to take a look at ?

No, not really. It’s an internal thing. My problem is that the
progress tends not to be reported very well. Oh, well, fuck it.

I tend to prefer either a timeout in the main thread that polls, or an
IO source that listens for events (either via a pipe or socket from an
external process). It makes it easier to throttle progress events if
there are too many & helps maintain a separation between the
processing code and UI implementation.
(But I also generally prefer to do all my heavy lifting in helper
scripts, rather than the GUI)
When you say it doesn’t run well, do you mean that the process is
generally unresponsive or that there’s a lag between the progressbar
update being scheduled and being drawn?

I don’t mean that it doesn’t work, I just mean that it’s slow. The
progress being monitored is mostly other Ruby code, that is slightly
computation intense, but also COM activity through WIN32OLE.
