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