    Is this from a sub-process (eg launched with exec)? If so, use open with a pipe:

    replace

    exec some command line

    with

    pack [text .t] -expand yes -fill both
    set fp [open "|some command line" r]
    fileevent readable $fp "writeToText $fp .t"

    proc writeToText {chan text} {
    if {[gets $chan line] < 0} {
    catch {close $chan}
    } else {
    $text insert end "$line\n"
    }
    }

    Maybe you'll aver a look into tkcon ( https://github.com/wjoye/tkcon ). stderr/stdout is redirected there to the text-Widget

    How about tcl::chan::textwindow in tcllib?
