-== Data Binding
-
-While [classname]#Label# is not a field component, it is a
-[interfacename]#Property.Viewer# and can be bound to a property data source,
-described in
-<<dummy/../../../framework/datamodel/datamodel-properties#datamodel.properties,"Properties">>.
-You can specify the data source either in the constructor or by the
-[methodname]#setPropertyDataSource()# method.

-[source, java]
-----
-// Some property
-ObjectProperty<String> property =
-    new ObjectProperty<String>("some value");
-
-// Label that is bound to the property
-Label label = new Label(property);
-----
-See the http://demo.vaadin.com/book-examples-vaadin7/book#component.label.binding[on-line example, window="_blank"].
-
-Further, as [classname]#Label# is a [interfacename]#Property#, you can edit its
-value with a property editor, such as a field:
-
-
-[source, java]
-----
-Label label = new Label("some value");
-TextField editor = new TextField();
-editor.setPropertyDataSource(label);
-editor.setImmediate(true);
-----
-See the http://demo.vaadin.com/book-examples-vaadin7/book#component.label.delegation[on-line example, window="_blank"].
-
-However, [classname]#Label# is __not__ a [interfacename]#Property.Editor#, so it
-is read-only when bound to a data source. Therefore, you can not use
-[methodname]#setValue()# to set the value of a connected data source through a
-[classname]#Label# nor bind the label to an editor field, in which case writes
-would be delegated through the label.
