Contrary to gtk, which has one type for each widget, there is only one abstract type in Evas and in Elementary: an Evas object. That object is a basic object or a smart object. Each widget in Elementary is an Evas object (an evas smart object, actually). When you create an Evas image object, you create an Evas_Object. Its creation is done with the following function: Evas_Object *evas_object_image_add(Evas *e); Same for a line, for example: Evas_Object *evas_object_line_add(Evas *e); or for an elementary background: Evas_Object *elm_bg_add(Evas_Object *parent) You always return the same abstract type. When you want to add an object to an elementary box, you also use an Evas_Object. There is only one type that is used. So an Elementary widget is an Evas object and an Evas object can be used as an Elementary widget. Funny, isn't it ? > besides, I found a "elm_image_add()" api, but i'm not sure it's useful or > not... as useful as elm_bg. hth Vincent ------------------------------------------------------------------------------ This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?
