to print subscripts in labels, I split a string and place the second
part of it some pixels lower than the first. However, each string is
surrounded by a box of background color, and in order to keep the
second string from covering part of the first, I have to space them
quite a bit apart. This would not be necessary if I could choose a
transparent background option. Unfortunately, tricks like -bg "" ore -
bg transparent did not work. I am using Tcl/Tk 8.4.14 from
ActiveState running in OS X 10.4.10.
Thanks for any advice!
