::com::sun::star::form::FormControlModel
Description specifies the basic functionality for a form control model Via this service, bindable control models inherit the ::com::sun::star::util::XCloneable interface. If an bindable control model, at which a binding has been established (via XBindableValue::setValueBinding), is being cloned, then the binding is also established at the clone. Effectively, this means that both control model instances share the same binding instance.

Exported Interfaces - Details
XBindableValue
Description specifies support for being bound to an external value When a BindableControlModel is bound to an external value, then every change in the control model's value is immediately reflected in the external binding. If the binding set via this interface supports the ValueBinding::ReadOnly and ValueBinding::Relevant properties, they're respected by the control model: The control model's own `ReadOnly` property (if present) is kept in sync with the binding's `ReadOnly` property. That is, any control using the value binding is read-only as long as the binding is. The control model's own `Enabled` property (if present) is kept in sync with the binding's `Relevant` property. That is, any control using the value binding is disabled as long as the binding is not relevant. In both cases, explicit changes of the model's property are ignored if they would relax the restriction imposed by the binding. For instance, if the binding declares it's value to be read-only (indicated by ValueBinding::ReadOnly being true), then any attempt to set the `ReadOnly` property of the control model to false will fail. However, if the binding's value is not read-only, then the `ReadOnly` property at the control model can be freely set. The very same holds for the binding's ValueBinding::Relevant and the control model's `Enabled` properties.
