unpublished service BindableDatabaseRadioButton
Usage Restrictions
not published
Description
This service specifies a radio button which is data-aware and thus can be bound to a database field, and additionally supports binding to arbitrary external values.

The XValueBinding instance which can be associated with a BindableDatabaseRadioButton must support exchanging boolean values. The following mapping between external values and control states apply:

  • true will be mapped to the button being checked, and vice versa
  • false will be mapped to it being unchecked, and vice versa
  • NULL will be mapped to it being in indetermined state

If the value binding associated with a BindableDatabaseRadioButton supports exchanging string values, and the ::com::sun::star::form::component::RadioButton::RefValue is not empty, then the radio button will exchange it's value as string:

  • A string equal to the reference value will be mapped to the button being checked, and vice versa
  • A string not equal to the reference value will be mapped to the button being unchecked, and vice versa
  • NULL will be mapped to it being in indetermined state
