The code about de progress bar is like this :

var info : stat;

    adj  : pgtkadjustment;

...

fstat (file_name, info);

...

adj := pgtkadjustment (gtk_adjustment_new (0, 1, info.size, 0, 0, 0));

progressbar := gtk_progress_bar_new_with_adjustment (adj);

...

and later the code i've sent before.

I think that the trouble is that the program loses the control of the main loop

while is reading the file and can't redraw the widget, what can i do ?

every time
