Managing long operations in a single-threaded application

[Arthur Jerijian <lightmanaj earthlink net>]

Hi all,

I need to perform a long operation, on the order of seconds or minutes, without
freezing the entire GTK-based GUI that I'm using. This operation has no
knowledge of GTK or its event messaging paradigm. Is there a way to perform
this operation while still processing GTK messages in just one thread?

Thanks,
