hiding Windows

[Derek Philip]

Hi all

This is more of a Tk programming problem than a VTCL one but I hope to 
implement it using VTCL.

I would like to have a several buttons which, on first press, open up an
xterm window and start a telnet session. 

When I press the button for a second time I would like to hide the window but not
close it or loose the telnet session this will have to be done explicitly. 


Any help would be appriciated

thanks 

Derek
