The Tk::Balloon doc says for the -balloonmsg option:
If you give it a scalar reference then it is dereferenced before being displayed. Useful if the postcommand is used to change the message.
It seems that it isn't necessary to utilize -postcommand for your problem, using a reference for -balloonmsg should suffice. | [reply] |
Aha! Right you are.
I must learn to read the documentation more carefully...
but I'm still using -postcommand as a way to decide when
to update the scalar that is being referenced by -balloonmsg.
Thanks!
