[UI Sample] Proxy Object Sample Overview

The Proxy Object sample demonstrates how to make a proxy object for an Evas object.

The following figure illustrates the main screen of Proxy Object.

Implementation

The following code snippet shows the struct for dealing with proxy objects.

struct anim_data 
{
   Evas_Object *btn;
   Evas_Object *img1;
   Evas_Object *img2;
};

The following code snippet demonstrates how to create proxy objects. The evas_object_image_source_set() function creates a proxy object for an Evas_Object. The evas_object_image_source_visible_set() function sets the proxy object to be visible.

void
proxy_exam(Evas_Object *win)
{
   static struct anim_data ad;

   ad.btn = elm_button_add(win);
   elm_object_text_set(ad.btn, "Proxy Object");
   evas_object_move(ad.btn, 100, 100);
   evas_object_resize(ad.btn, 200, 200);
   evas_object_show(ad.btn);

   Evas *evas = evas_object_evas_get(win);
   ad.img1 = evas_object_image_filled_add(evas);
   evas_object_image_source_set(ad.img1, ad.btn);
   evas_object_image_source_visible_set(ad.img1, EINA_FALSE);
   evas_object_move(ad.img1, 100, 100);
   evas_object_resize(ad.img1, 200, 200);
   evas_object_show(ad.img1);

   ad.img2 = evas_object_image_filled_add(evas);
   evas_object_image_source_set(ad.img2, ad.btn);
   evas_object_move(ad.img2, 100, 300);
   evas_object_resize(ad.img2, 200, 200);
   evas_object_show(ad.img2);
}
