Isn't that they way that most systems do it now-a-days? It certainly is
that way with wxPython.

The best way to take a look at what is possible with wxPython is to
download it and run the demo. ( - other
stuff might be needed.). I've got most of the parts laying around so if
you want to give a try, contact me offlist ( - be
forewarned that you'll have to deal with my anti-spam challange/response

My own experience with wxPython is that on Linux the
windows/controls/dialogs are more asethetic, flexible, and responsive than
those in Java but are still not really visually stunning. On Windoz
wxPython uses native controls when possible, so it inherits most of the
Microsoft characteristics and aesthetics.

I've just checked - the wxBitmapButton object in wxPython can have three
different bitmaps: for unselected, for selected, and for disabled. That
gives some flexibilility, but doesn't allow for "effects" (such as a
flash) when the button is "pushed".

Generally people who see wxPython stuff think that it looks more
"professional" on Windows than on Linux. But then again, I think most
user interfaces look better on Windows than on Linux (which, being a Linux
wannabe, I find disturbing.)

I missed it, but I've got it up on my screen now...

My concerns are these:

1. The overall screen is "busy", if a ballot had that much stuff I suspect
that voters would often complain of being confused.

2. I suspect that the button spacing is too close for use on a ballot. We
gotta expect people who are older and less capable than the typical
restaurant wait-folk.

3. In an earlier post I suggested having a check box in addition to a
visual change on the button itself. There was at least some positive
reception on this. Do you think that is a useful thing to have or would
you think that the same information can be conveyed in the button itself?
