You need to use the
update
command between pings etc as Tk/Tcl only updates
during idle times otherwise

man update(n) (i think) will probably show more info

Subject: TCL/TK:How to pop-up a windows before end of prog


>Hi everyone,
>
>I wanted to know how to do this trick: I want to make
>a little tcl/tk program that will ping some machine
>and show the result (if the machine is there or not)
>in a graphical window so that I can show the machine
>which are there in a certain color and a certain set
>of caractere. But I want to see them appear in that
>windows immediately when the ping command is done. But
>the way I do it, the program ping all the machine and
>the result appear only when the progam is done. Is
>there a way to make the window appear immediately when
>the first machine is found and that the user can see
>the line appear in the screen of that window. In one
>word, I want to make it in real-time and see the
>output immediately on a newline each time a ping is
>done, not to see all the ping at the end when the
>program have tried them all. (Presently, I'm doing a
>"$t insert end "result of the ping = $var_ping" to
>make the result appear in my graphical window).
