Tk, quickie

Any time the selection changes in the listbox, the virtual event <<ListboxSelect>> will be generated. It is easiest to bind to this event to be made aware of any changes to listbox selection.

assuming $LB is my listBox, how can I use the above to do something whenever something in the list is selected?

(I just don't know the syntax)

Try:

$LB->bind ('<<ListboxSelect>>', sub {
   print "The selection has changed!\n";
   my $index = $LB->curselection;
   my $value = $LB->get ($index);
   print "The new value is: $value\n";
});

If the listbox allows multiple selections, curselection returns an array of indices, and you'dd need to get each one.

That doesn't work... doesn't seem to be catching the Event..

Any other ideas?
