OK, with some trial-and-error, now I've understood the use of lift (it
accept a function as first parameter that can render some widget, during
"transformation" of signal passed as second parameter).
But now, problem is: how can I intercept signal generated from button
pressure?
In Escher example 'form.jl' trigger!() is used, but example doesn't work ...
Any suggestion is appreciated
