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.
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.
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.
