Re: GTK Progress bar: assistance pls.

Hey Bin Chen[or how do I call you :-)],

First of all, thank you very much for your instant reply.

Let me give a simple pseudo-code explaining my problem. Please see what I
can do with this.

Program Goal: Do work w1 "iterations" number of times, and keep showing
progress of this whole work regularly.

Pseudo code:

for(i=0;i<iterations;i++)
{
    do w1;
    fraction = (i+1)/iterations;
    Update progress bar using this fraction.
}

This is what I coded, and the progress bar never got updated until
fraction was 0.99[that is, the progress bar went from zero to 100 % after
the whole work was done].

As far as the above pseudo-code goes, the progress bar here doesnt have to
understand my logic of estimating progress fraction. It simply has to
update the fraction given to it regularly.


Please help me[again :-)]
