Are we talking about the same thing? Interface and implentation are overloaded terms.
// text struct text_element : graphics_element {..}
// edit box struct active_text : text_element,user_action_handler, draw_handler{..};
Except that on PlamOS, when using resource files, I don't need a draw function for my text boxes. I know they are draw somehow, but not by the Boost.GUI library. Could this be what I'm saying? struct graphics_element{ virtual void draw(Context c) =0; }; struct text_element { virtual void display(std::string s); } template <typename IdType> struct resource_binder { IdType resource_id; } // PalmOS edit box. struct resource_edit_box : text_element, resource_binder, user_action_handler, draw_handler{..}; // Drawn edit box. struct graphic_edit_box : text_element, graphics_element, user_action_handler, draw_handler{..}; -- Alan Gutierrez - alan@engrm.com
