pythondialog can't do that natively in its present state, AFAIK. It is
probably possible, in similar ways as mentioned in my previous mail, to
translate the touch screen events into keyboard events or terminal
input, but the best solution is probably to make dialog behave a bit
like mc (Midnight Commander), which is able to recognize mouse clicks in
several terminal emulators (tested in XTerm, Konsole and the Linux
console, not sure about other terminal emulators). Since mc is based on
ncurses like dialog, the technology is the same. The only thing is that
you want to work with a touch screen instead of a mouse, but it seems to
me it is only one more case to deal with in the relevant software
component, i.e., ncurses and/or terminal emulators.

Well, there still is some complexity if this has to be handled at
terminal emulator level, which I would expect, because depending on what
you use (Linux console or X terminal, or Wayland terminal or...), the
drivers to read touch screen "clicks" are not the same (Linux kernel in
the first case, X.org in the second one; one could also consider
Wayland, OS X...). If I were in your place, I would talk to Thomas
Dickey about this, because he knows the whole terminal software stack
(ncurses, dialog and XTerm maintainer!).

This sounds like a customization of the fselect widget and must be
implemented in dialog (in C) before pythondialog can offer it. Again,
your best bet here is to contact Thomas Dickey or an ncurses mailing
list. I am sure Thomas would gladly accept a well-written patch. :-)

Sorry for not being able to provide more concrete help...

Ah, what is the problem exactly? Is there no error message? I am
replying to the list for the benefit of other users, since that was
apparently your intention (and putting you in Cc just in case, please
tell me if this is unwanted).
