Tizen基本照片小部件

流星悟语

这段代码演示了如何使用基本的照片部件。这个小工具的目的是展现人的照片。当没有图像加载它显示一个占位符。

1. // create box for our photo objects
   
2. Evas_Object *box = elm_box_add(ad->win);
   
3. evas_object_size_hint_weight_set(box, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);
   
4. elm_win_resize_object_add(ad->win, box);
   
5. evas_object_show(box);
   
6. 
   
7. // create the first photo
   
8. Evas_Object* photo = elm_photo_add(ad->win);
   
9. evas_object_size_hint_weight_set(photo, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);
   
10. evas_object_size_hint_align_set(photo, EVAS_HINT_FILL, EVAS_HINT_FILL);
    
11. 
    
12. // set  photo file (PHOTO_DIR should look like this "/opt/usr/apps/org.tizen.myproject/res/images")
    
13. char file[PATH_MAX];
    
14. snprintf(file, sizeof(file), "%s/image.png", PHOTO_DIR);
    
15. elm_photo_file_set(photo, file);
    
16. 
    
17. evas_object_show(photo);
    
18. elm_box_pack_end(box, photo);
    
19. 
    
20. // create another photo without sending an actual image file - placeholder is shown
    
21. Evas_Object* empty_photo = elm_photo_add(ad->win);
    
22. evas_object_size_hint_weight_set(empty_photo, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);
    
23. evas_object_size_hint_align_set(empty_photo, EVAS_HINT_FILL, EVAS_HINT_FILL);
    
24. evas_object_show(empty_photo);
    
25. elm_box_pack_end(box, empty_photo);
