I am creating a Perl/TK GUI code that will call a seperate exe inside. The progress bar widget will be the only indication that execution is happening inside it but problem is, as you run the code, the progress bar freezes because it has to finish first the execution of the seperate exe and after it's done, activity on the progress can be updated.
Is there a better way to have a simultenous implementation of the progress with respect to the seperate exe so as to have the real time execution of the code?
