kcott, thank you very much!

The example really does what I need but unfortunately it doesn't show correctly the progress bar of the command. This is probably due to the fact that the textual progress bar includes a counter which is implemented by printing "\r" char (below the entire C function).

void doProgress(char* label, size_t step, size_t total) {
    //progress width
    const int pwidth = 60;

    //minus label len
    size_t width = pwidth - strlen(label);
    size_t pos = (step * width) / total;

    size_t percent = (step * 100) / total;

    printf("\r%s%4d/%4d [", label, step, total);

    int i;

    //fill progress bar with =
    for (i = 0; i < pos; i++) {
        printf("%c", '=');
    }

    //fill progress bar with spaces
    printf("% *c", width - pos + 1, ']');
    printf("%3d%%", percent);
    fflush(stdout);
}

The net result is that I get a mess displayed when I add the text to the TextView, because TextView doesn't interpret char escape sequences. I get the same result using Tk::DoCommand.

After a little bit of searching I think that I could probably solve the thing by using pseudo-ttys in Tk or even embedding Xterm(1) inside Tk !

The two examples are all in python, so I'd just ask if the same can be done with Perl Tk (maybe playing with IPC::Run module pseudo-ttys support) ?

Comments and further suggestions are always welcome!
