I've been staring at e_livethumb.c and e_widget_preview , e_int_config_theme.c, where it is used and trying to develop an understanding of the relationships so far, i'm missing a tiny link. As I understand (from a day+ of Esmart/Evas/Ecore_Evas induction), when I'm creating an evas esmart object, I create all my individual evas objects, poke them into the esmart data and write call backs that manipulate. In my initializer, I take an evas, add the esmart object to it and this action results in an Evas_Object that is linked to my evas and is an instance of my esmart. Once I manipulate this new evas object, i'm well and happy. *please correct me if i'm wrong at any step* Now, for using the buffer canvas, I don't seem to see how to relate the ecore_evas_object_image_new() that i create to the rest of the esmart objects. Normally, in the examples I've seen and the minientrance code I sent, I had a *clip* member that was an evas_rectangle (honestly, I'm not sure what that clip is used for :) ), but when I created by background object and main object, i set their clip to the internal clip object, and in the clip_set callback, i set the passed in clip to the internal clip. This is how I seem to see that all the objects in my evas get linked together. Looking at e_livethumb, I see that the ecore_evas_object_image is created and a smart member is set on it (that's where I first start getting confused.) Next, in e_livethumb_thum_set(), I was expecting that i'd see the thumb member being somehow linked to the buffer canvas (evas_obj), but its not happening. Instead the thumb is being sized on its own. So my question really is how do these hook up together, when using the buffer canvas. I'm sure i'm missign something small, but i just can't seem to see it. :) cheers, Essien <snip> ------------------------------------------------------------------------- Using Tomcat but need to do more?
