Hi Fabien,
As an idea is good .. I found it very interesting..
I also thought do something similar at the form level, but this implementation
requires me to place all components that depend on a Firmata on the same
container, forcing distribute all controls on a linear, horizontal or vertical.
This ends up being an important limitation when build a user interface.. Mainly
at the time of using several firmata drivers, and I want to combine the
controls in a single graphic interface. :S
Unlike is the case of DataView (I think this is a component that was appointed)
where all information should be displayed linear homogenously.. This is not the
case.. Here each control is different and can dritribuirse through the entire
form
Thanks for all,
Regards,
Matias.
