Re: Interface freeze during long operations...

[Fabien Bouleau <bouleau alsace u-strasbg fr>]

Two problems here : first, you should sometimes flush events with
something like :

  while(gtk_events_pending())
     gtk_main_iteration();

in your loop. Secundo - and there is no tidy solution - scanning uses
hardware IRQ, which one prepends on all other interrupts. A non-maskable
interrupt is mainly used in this case, but I don't think GTK does the
job...
