You're right about the width option (I was thinking of ttk.Button).
However, I've found two problems with this approach:
(1) button widths differ per platform (so on Windows 7 I need -11 and on
Linux -9; and this may vary with DPI or other factors, so setting
width may not be a good idea)
(2) the text is centered (like the other buttons) when in TButton style;
but is left aligned in Toolbutton style. And there doesn't seem to
be a justify option for ttk.Checkbuttons.
So, for now, I'm using the style approach for Linux since it works
perfectly there, and for Windows and Mac OS X I'm adding an image to the
button with one image for selected and one for deselected.
Thanks!
