Hello,

I'm trying to build up a physics simulation with Glade and GTK. The main
function of the simulation is a function called isingflip(). This
function must do interations up to 1000000 times but the calculation is
based on two variables controlled by two scrollbars defined in the main
window. I have already put signal to pass the value of the scrollbars to
the variables and it works. But when I launch the simulation by clicking
on a button called "Simulation", the program does the calculations but
while doing this, I cannot move anymore the scrollbars to change
parameters.

Is there a way to let me change parameters ? Maybe lookup signals or
somenthing like that ? I've heard something about threads but I don't
know what it is.... I'm really a newbie so if someone could give me some
very detailled way to do this, it would be very nice.

Thanks a lot
