in reply to Re^3: Clearing anonymous Tk widgets
in thread Clearing anonymous Tk widgets
Unless I've done something silly (highly plausible explanation!), I'm not seeing evidence to support that theory. $_ is the value of the key when I build the line in the GUI window and it displays exactly as I'd expect it to and when I put a button on the line saying delete $runtime{$_} it works the first time then objects the second time (makes sense too - the delete worked, so there's nothing there now). So now I want to remove the line from the GUI and I don't have a Tk widget name to destroy.
