Thank you for your patch.

@cedric @woohyun I will finish fixing the code according to the feedback by next week.
Besides the miscellaneous issues, I need your opinion on major concepts.
Please look through the structure and let me know if you have any concerns.
I have one!

@cedric
Please see https://phab.enlightenment.org/D5832 for the latest version.
I'll abandon this revision after I check if there's anything to consider from the comments.

This patch removes legacy theme and refactors sample code.

Fixed codes according to @cedric's feedback.
@woohyun's comments will be done soon.

evas_object_image_size_set()
evas_object_image_load_size_set()
evas_object_image_load_scale_down_set()

Looks good to me.

I rebuilt the code from the scratch and here is the new branch:

I have been working on building classes to support page view in efl and just pushed the results so far.

Should each property in Elm.Interface_Scrollable be a part of Efl.Ui.Scrollable interface?

@taxi2se Can you please add a test case as @cedric and @jpeg said?
I agree that this case is not perfectly suitable for elementary_test for now,
but it needs to be developed into a decent test suite in the future.

static void
_down_cb(void *data, Evas *e, Evas_Object *obj, void *event_info)
{

printf("MOUSE DOWN!\n");
fflush(stdout);

}
