Dear Gustavo Sverzut and Gustavo Lima, I'm really grateful for your helps :) and it is great that I can inherit Elementary widgets later! I'm going to prepare new patch to expose new API to set property after creating my Evas_Object by referencing the Elementary widgets.
Actually, it is similar with my first approach to make my Evas_Object inheritable with property. But at that time, I doubted that it is right approach because the Evas_Object which inherits my Evas_Object has to be sure to call API to set property in its constructor. So, I wanted to find the way that the Evas_Object which inherits my Evas_Object can not forget to do additional work to set property, and I failed. Anyway, now I'm happy because I've got the way which is acceptable and accredited in the EFL :) I want to say thank you again. Additionally someday, I hope that Evas_Object can support additional parameters in the evas_object_smart_add(). In the GTK, they can set properties to the g_object_new() function and the properties are saved as g_property. so, the properties can be used later such as g_object's constructed() function. I don't know well how GTK works, but I envy that functions.
