Thanks for the help, but it's still not getting updated.
I'm thinking that the problem could be this piece of code that I have:
# If already initialized, just turn on
if { [winfo exists .myplugin] } {
wm deiconify $w
return
}
But removing it did not help since now I get (when calling myplugin_tk):
"window name "myplugin" already exists in parent".
So, how do I kill the existing old window?
BR,
Anssi Nurminen
