ttk:checkbutton is missing the toggle command?

[Alexandru]

I was assuming, that the ttk:checkbutton has the same commands as the checkbutton but I was wrong(?)

E.g. the "toggle" command in not available for the themed version?

Same vor the "select" and "deselect" commands...

The Tk checkbutton's "toggle" command is the ttk::checkbutton's
"invoke" command.

pathname invoke
*Toggles* between the selected and deselected states and
evaluates the associated -command. If the widget is
currently selected, sets the -variable to the -offvalue
and deselects the widget; otherwise, sets the -variable
to the -onvalue Returns the result of the -command.

The "select" and "deselect" commands were subsumed into the state
mechansim.

See the ttk_intro and ttk_widget man pages.

The Tk select is now:

widgetname state selected

And the Tk deselect is now:

widgetname state !selected

Thanks for the explanations.
I see that now. I was naive to think, that the themed widgets are same old widgets with an added -style option and removed old specific styling options such as -fg.
Since I always propagate the use of ttk widgets over the old widgets, I realize the difficulty for old codes to "simply" switch the technology from old to new. Maybe this is one of the reasons why we still see lots of the old UIs out there. That's a pitty.
