  • X11 resources in Tkinter or C tcl/tk

    This should be an easy question to answer with Google, but so far I
    have failed...

    I have a small program (actually written to try out LLM assistance for
    the first time) written in Python with Tkinter and ttk. I very rarely
    use tcl/tk myself.

    I can see that it is making some use of the X11 resource database,
    because it picks up my default background colour (light brown), and I
    can change that by setting the tk*background resource.

    I can't see how to use X11 resources for anything else, though. And I
    can't see even by grepping the tcl/tk source code where it's picking
    up the background colour!

    Is it possible to do any control of colours in a tkinter application,
    or more generally any tcl/tk application via the X resource database?
    Is it possible to specify the names (in the Xrm sense) of tk widgets -
    does the className do that
