Hi ...
Found that setting the ttk.Checkbutton style to 'TButton' forces it to appear
as
themed button; then, on selection, changing it to 'Toolbutton' gives it a
'sunken' appearance. Works ok under Windows 7.
cb1 = ttk.Checkbutton(f, style='Demo.TButton',
image=(self.noletters, 'selected', self.letters),
command=lambda: self._cb_value_changed(cb1))
def _cb_value_changed(self, cb):
# if a checkbutton is selected, use the 'Toolbutton'
# style to make it appear 'sunken'
if 'selected' in cb.state():
cb['style'] = 'Demo.Toolbutton'
else:
cb['style'] = 'Demo.TButton'
