Hi Andrew,

you can push :tk84 onto *features*, then it won't use any 8.5 features and you get the old style widgets.
Otherwise, if you only want the old-style button widget, you can change its definition from ttk::button to just button in the ltk source.

Best regards,
Peter

You mentioned a while ago that from Tk5 on, ttk doesn't allow changes in background color of buttons.  This breaks a program of mine.  Is it possible to work around this by choosing a different widget set, either within Ltk or in Tk config files?
