FormerCheckbox<TForm extends FormerForm> class

A normal Checkbox that

  • updates the value of the given field in the form whenever it changes.
  • follows whether the form is enabled (can override in constructor)

The given field has to be:

  • a boolean field (tristate must be off), or
  • a nullable boolean field (tristate must be on).

If the field is incompatible, an AssertionError will be thrown.
