Both the developer guide and the API documentation mentions a DevelButton::Property that should be used instead of some Button::Property members. Please see the following documentation pages:

https://developer.tizen.org/development/guides/native-application/user-interface/dali/ui-components/buttons#Buttoncreation

https://developer.tizen.org/dev-guide/4.0.0/org.tizen.native.wearable.apireference/classDali_1_1Toolkit_1_1Button.html

Furthermore the description of the button properties mentions several constants that I suspect is defined in the DevelButton::Property enumeration:

https://developer.tizen.org/dev-guide/4.0.0/org.tizen.native.wearable.apireference/structDali_1_1Toolkit_1_1Button_1_1Property.html

For example, the SELECTED_STATE_IMAGE is deprecated and we are supposed to use SELECTED_VISUAL since Tizen 3.0. However, SELECTED_VISUAL is not defined in the Button::Property enum. I suspected that SELECTED_VISUAL was defined in a DevelButton::Property enum instead. However, I cannot find any definitions for DevelButton in the Dali files provided with Tizen 4.0 or 3.0. Please help!
