Hello all,
anybody have a hint on this?
I have a c/c++ programme that is called from within a
widget hierachy via call_external.
As the computations made take fairly long, I want to update
a status bar with a 'Percentage complete' from the C-routine,
so the user doesn't get upset and thinks the programme died
on him/her.
How do I go about that???
Dominic

Humm. Yes. I can see how that might happen. :-(
I'm afraid you might have to figure out some
way to go with JD's suggestion of interrupts.
Completely out of my league, though, sorry.
Cheers,
