[AWS] What's the 'best' way to use AWS as a end-user interface tool ?

[brett hallett]

I need to create a very small data capture form for myself and decided
to try Ada + AWS + Browser rather than wade into GTK+ as the GUI
interface. The data entry form is not very complex and does not require
a large widget set.

Using the example code in GEM #29, I have a program interacting with a
web page using despatchers.URI, with additional URI messages I have
added, but these are of course entered into the web browser 'command
line'. I now wish to develop the program to respond to user click-able
buttons on the form.

The typically : first , last, next, back, clear, save, delete, exit :
buttons are intended, and the Ada program should display the desired
previously entered record(s), however, I am unsure how to 'connect' a
HTML button click in such a way that the dispatcher is called to direct
the button click to the desired Ada function(s) in my program.

What little information I could find regarding AWS usage just glosses
over the actual handling of multiple user-clickable buttons on a form.

Any advice appreciated.
