Dear Hermet Park,
Thank you for your response. I am honestly grateful for your help,i progressed, but it's not all.

This sreenshot that i done.

imageup . ru / img119 / 2341449 / selector . jpg
First problem is that this two circle without image, all my images are in folder /res, why i have empty circles?what wrong with is?

Second problem is the following: when i "run -debug", it opens in emulator gear s2 and all work. But after restarting application inside the clock emulator it don't work(it shows black screen).
Third issue
In this documentation that i send you, i change "parent" to "ad->nf" in this code examples, and all this started working.Why?And i see in more code snipets this  parent. What is "parent"? For example:
 

Evas_Object *rotary_selector, *parent;

Rotary_selector = eext_rotary_selector_add(parent);

    when i used this it gives me: 
'parent' is used uninitialized in this function [-Wuninitialized]

but when i change, it works.

Evas_Object *rotary_selector

Rotary_selector = eext_rotary_selector_add(ad->nf);

This is my full code. (it works)
