Ttk is the new Tk themed widget set. This is a Ttk themed label, \
|
|
and below are three groups of Ttk widgets in Ttk labelframes. \
|
|
The first group are all buttons that set the current application theme \
|
|
when pressed. The second group contains three sets of checkbuttons, \
|
|
with a separator widget between the sets. Note that the "Enabled" \
|
|
button controls whether all the other themed widgets in this toplevel are \
|
|
in the disabled state. The third group has a collection of linked \
|
|
radiobuttons.
