Setting up the application

In this part of the tutorial, we create a simple application that manipulates and animates an Evas object. We use a ā€œBasic UI Applicationā€ as the basis for the application.

First, we set up the widgets we are going to use in the application:

elm_main(int argc, char **argv)
   //Main window
   Evas_Object *win;
   //Application Title
   Evas_Object *label;
   Evas_Object *bt1, *bt2, *bt3;
   //Animation target
   Evas_Object *target;
   return EXIT_SUCCESS;

Then the actual widgets are created, starting with the main window and application title:

//Main window
win = elm_win_util_standard_add("Ecore Animator", "Ecore Animator Tutorial");
elm_win_autodel_set(win, EINA_TRUE);
if (elm_win_wm_rotation_supported_get(win))
     int rots[4] = { 0, 90, 180, 270 };
     elm_win_wm_rotation_available_rotations_set(win, (const int *)(&rots), 4);
// Application title
label = elm_label_add(win);
elm_object_text_set(label, "Ecore Animator Tutorial");
evas_object_size_hint_weight_set(label, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);
elm_win_resize_object_add(win, label);

Next, we create the animation target, which is an Evas object of type Elm_Image.

// Animation target
// Setting the image path
char buf[PATH_MAX];
snprintf(buf, sizeof(buf), "icon.png");
// Adding the image
target = elm_image_add(win);
// Setting the image path
if (!elm_image_file_set(target, buf, NULL))
       printf("error: could not load image \"%s\"\n", buf);
evas_object_size_hint_weight_set(target, EVAS_HINT_FILL, EVAS_HINT_FILL);
//Moving the image
evas_object_move(target, 130, 100);
//Resizing the image
evas_object_resize(target, 200, 100);
//Showing the image

The image path is set by calling the elm_image_file_set() function. This function takes as arguments the target Evas object and the path of the image file, built with the snprintf() function and stored in a buffer.
