With a grouped set of PushButtons all in toggle mode. I can de-
select the
currently selected button so that no buttons are selected. Is there
a property
somewhere that can be set so that a toggle button in the group is
always
selected? Just like the radio buttons do by default.
PushButtons don't currently support such a property, though it would
be easy enough to add one. Alternatively, you could create a custom
subclass of PushButton that overrides press() to achieve the behavior
you need.
If we were to add a property like this, what might you expect it to be
called?
