Hi Jon,
thanks for the input!

This could be easily done using the '<style>' function or the '+Style'
prefix class, e.g. by replacing the field definition
(gui '(+Var +NumField) '*DemoNum 10)
with
(<style> '(pattern . "[0-9]*")
(gui '(+Var +NumField) '*DemoNum 10) )
or with
(gui '(+Style +Var +NumField)
'(cons 'pattern "[0-9]*")
'*DemoNum 10 )
For the '+FixField' the pattern should probably extended for the decimal
point, and a '-' for negative numbers might also be necessary.
Note that '<style>' could be used for a whole bunch of fields
(<style> '(pattern . "[0-9]*")
(gui '(+NumField) 10)
...
(gui '(+NumField) 10)
... )

This is difficult, if not impossible. The menu is implemented as anchor
elements in an unordered list. Clicking outside it doesn't generate an
event.
Perhaps it could be solved with some JavaScript trick, but this would
break the fundamental rule that the GUI should also work in an
environment without JavaScript (e.g. on text browsers).
