If you're showing percentages, only update the progress bar
when the percentage digit changes. eg:
int last_percent = 0;
while ( ..load file line loop.. ) {
percent = (int)((float)line / total_lines * 100.0 + .5);
if ( percent != last_percent ) { // integer percentage changed?
..update progress bar + Fl::check()..
last_percent = percent;
}
}
This way you only update at max 100 times no matter
how large the file is.
