Please open FormsIO.lava in LavaPE.
This is a minimalistic example of semi-automatic form generation from Lava classes.
Please open BigForm.lava in LavaPE.
This is a more complex (although arbitrary) example which demonstrates most of the possibilities to automatically generate and to manually modify forms from Lava classes. It exhibits also the new expressive means to specify fonts and foreground/background colors for entire forms, sub-forms or individual "atomic" form elements.
Both samples are runnable.
