OK - you need to give us more info: What fltk version, what host OS, etc. What you are trying to do souds like it should work easily enough, though... > but when the file reading loop starts, Fl::check() make time interval i > think so. progress bar is showing without any problem. but the speed of > line reading is reduced 100 times may be.

Are you updating the GUI for every single line you read from the file? If so, you probably do not want to do that - updating the display is "expensive" so triggering updates where there's no change the user can even see if pointless, but will slow your code down. Similarly, calling printf/cout is expensive too (though not as slow as updating the GUI usually!) so if you are interested in speed you must not put that inside the loop either! For the progress bar case, it probably makes sense to compute the progress value, and only update the display widget if the value is substantially changed - I usually go for every 3% or so...
