looking at defaults.tcl helps :)

At least here on X11 with default ttk style

st.configure('TScrollbar', width='10m', arrowsize='10m')

works.

With the default style scaling a checkbutton with

st.configure('TCheckbutton', indicatordiameter='10m')

also works, not with the "alt" theme though (I guess they are using a
bitmap there again).

Best regards

Michael
