Yes, but I needed the user to be free to start using all
program features, even while the treeview is growing. So he can
open trees, doubleclick, use menu items and even stop the scan.

You are programming by coincidence[1]. If you actually understood
how Gtk2 works, youâd know that the loop Jan mentioned enables
exactly the behaviour you want, and you could avoid a lot of

By way of an explanation: a GUI program works by having a
mainloop which runs indefinitely and checks whether the user did
anything. For anything the user does, it registers an âevent,â
then calls handlers to react to that event. Gtk2->main_iteration
does that for exactly one event. If there was no event pending
processing, it blocks (so you donât want to call it if there are
none). Gtk2->event_pending checks whether thereâs anything in the
queue. That means that the loop Jan mentioned will process any
clicks, redraws, etc which were queued up when the program was
busy, any time it has a moment to spare.
