This is a simple example in which we create a rect and swallow it.
Focusing on the relevant parts of the code we go right to the creation of our rectangle. It should be noted that we don't resize or show our rect, that is because when an object is swallowed it's geometry and visibility is controlled by the theme:
edje_object_part_swallow(edje_obj, "part_one", rect);
The other bit of code that is relevant to us now is our check that the swallow worked:
obj = edje_object_part_swallow_get(edje_obj, "part_one");
if(obj == rect)
printf("Swallowing worked!\n");
The full source code follows:
#ifdef HAVE_CONFIG_H
# include "config.h"
#else
# define EINA_UNUSED
#endif
#ifndef PACKAGE_DATA_DIR
#define PACKAGE_DATA_DIR "."
#endif
#include <Ecore.h>
#define WIDTH (300)
#define HEIGHT (300)

edje_obj = edje_object_add(evas);
edje_object_file_set(edje_obj, edje_file, "example_group");
edje_object_part_swallow(edje_obj, "part_one", rect);
obj = edje_object_part_swallow_get(edje_obj, "part_one");
if(obj == rect)
printf("Swallowing worked!\n");
return EXIT_SUCCESS;
