Support activating / deactivating form fields #28

Closed joergreichert closed 8 years ago

joergreichert commented 8 years ago

Currently Rhei Forms expects always a pure widget on the right side as with using an composite the layout gets broken, so it isn't possible to create a form field, that is preceded by a checkbox, to state if the value of the form field should be used (indicating a null value instead of just an empty value).

Have a look at org.polymap.rhei.field.BetweenFormField. It creates/uses a Composite as control.

What exactly is the problem with the broken layout?

And: if a field is not modified by the user then it is not dirty and not gets submitted (checkbox=off). If the user modifies something, then it is indicated in the UI (valid or not). (checkbox=on). In other word: the user indicates that the value of a field should be "used" by modifying it. What is the point of the additional checkbox?

Ok, using the same approach as BetweenFormField (= with composing FormFields) works. Thanks for the hint.
