I have a similar setup in one of my apps, where I use a "checkbutton"
image in col #0 so the user can select or deselect a list entry. It
works, but is not perfect, though: there does not seem to be a way to
make only the "checkbutton" icon sensitive to mouse clicks, so the
"checkbutton's" state changes even when the user clicks somewhere in col
#0 next to the icon. And the "active rectangle" appears only as a tiny
dotted rectangle between the icon and the text which is in col #1.
The setup I use, which apart from the above issues I think looks good
enough, is

        treeview.configure(show=('tree', ), columns=('foobar',))
        treeview.column('#0', width=35, stretch=0)

Best regards

Michael
