This example will show you how to load an image using evas and fill a swallow with it.
It's basically almost like the last example, but with a minor change.
This variables are used to store the name of the image that is going to be used, the path to it and a variable that will store the error cause if something goes wrong.
Here it is:
const char *edje_file = PACKAGE_DATA_DIR"/swallow.edj";
const char *img_file = PACKAGE_DATA_DIR"/bubble.png";
Evas_Load_Error err;
Then we load the image with this command:
img = evas_object_image_filled_add(evas);
evas_object_image_file_set(img, img_file, NULL);
To check if we had some problem we use:
err = evas_object_image_load_error_get(img);
if (err != EVAS_LOAD_ERROR_NONE)
{
fprintf(stderr, "could not load image '%s'. error string is \"%s\"\n",
goto shutdown_edje;
}
Now we are going to swallow it and check if worked. If you notice we are using "part_one" as argument. We do this because we must explicit what part of our .edc file we want to swallow:
edje_object_part_swallow(edje_obj, "part_one", img);
obj = edje_object_part_swallow_get(edje_obj, "part_one");
if(obj == img)
printf("Swallowing worked!\n");
The example's window should look like this picture:
The complete .edc file:
collections {
group {
name: "example_group";
max: 500 500;
min: 50 50;
parts {
part {
name: "part_one";
type: SWALLOW;
description {
min: 50 50;
state: "default" 0.0;
rel1.relative: 0.0 0.0;
rel2.relative: 1.0 1.0;
}
}
}
}
}
And the source code:
#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)
static void
{
}
int
{
const char *edje_file = PACKAGE_DATA_DIR"/swallow.edj";
const char *img_file = PACKAGE_DATA_DIR"/bubble.png";
Ecore_Evas *ee;
Evas_Load_Error err;
return EXIT_FAILURE;
goto shutdown_ecore_evas;
if (!ee) goto shutdown_edje;
evas_object_move(bg, 0, 0);
evas_object_resize(bg, WIDTH, HEIGHT);
edje_obj = edje_object_add(evas);
edje_object_file_set(edje_obj, edje_file, "example_group");
evas_object_move(edje_obj, 20, 20);
evas_object_resize(edje_obj, WIDTH - 40, HEIGHT - 40);
img = evas_object_image_filled_add(evas);
evas_object_image_file_set(img, img_file, NULL);
err = evas_object_image_load_error_get(img);
if (err != EVAS_LOAD_ERROR_NONE)
{
fprintf(stderr, "could not load image '%s'. error string is \"%s\"\n",
goto shutdown_edje;
}
edje_object_part_swallow(edje_obj, "part_one", img);
obj = edje_object_part_swallow_get(edje_obj, "part_one");
if(obj == img)
printf("Swallowing worked!\n");
return EXIT_SUCCESS;
shutdown_edje:
shutdown_ecore_evas:
return EXIT_FAILURE;
}
