Description
The check box input widget allows for the capturing of data of type boolean
.
The widget allows for binding to a basic data type variable directly or to an object instance attribute.
The title is specified as a key to a lang file entry and is required. A tooltip can also be specified as a key to a lang file entry but is optional. Visibility bindings are also supported.
A new addition in version 1.57.0 (specific to the new UI) is the description
attribute. The description attribute works similarly to the title in that it is specified as a key to a lang file entry, however, its purpose is to allow for additional information related to an input and will appear beneath the input.
Example
Model object attribute
persistent object Farmer { . . // Attributes for messaging opt-in bool emailMessaging; . . }
View XML
<checkbox label="checkbox.opt_in_email_messaging"> <binding variable="farmer"> <attribute name="emailMessaging"/> </binding> </checkbox>
Backing unit
Farmer farmer; . . void init() { farmer = Farmer:user(); }
en.lang file entry
checkbox.opt_in_email_messaging = Opt in for messaging by E-mail:
