tizen如何使用基本ctxpopup小部件的代码

流星悟语

这个代码片段演示了如何使用基本ctxpopup小部件。

1. static void ctxpopup_item_cb(void *data, Evas_Object *obj, void *event_info) {
   
2.         printf("item selected: %s\n", elm_object_item_text_get(event_info));
   
3. }
   
4. 
   
5. static void dismissed_cb(void *data, Evas_Object *obj, void *event_info) {
   
6.         evas_object_del(obj);
   
7. }
   
8. 
   
9. static void show_ctx_popup(void *data, Evas_Object *obj, void *event_info) {
   
10.         appdata_s *ad = (appdata_s *) data;
    
11. 
    
12.         Evas_Object *ctxpopup = elm_ctxpopup_add(ad->win);
    
13.         elm_object_style_set(ctxpopup, "dropdown/list");
    
14.         eext_object_event_callback_add(ctxpopup, EEXT_CALLBACK_BACK, eext_ctxpopup_back_cb, NULL);
    
15.         evas_object_smart_callback_add(ctxpopup, "dismissed", dismissed_cb, NULL);
    
16. 
    
17.         //add list of 3 items
    
18.         elm_ctxpopup_item_append(ctxpopup, "Item 1", NULL, ctxpopup_item_cb, NULL);
    
19.         elm_ctxpopup_item_append(ctxpopup, "Item 2", NULL, ctxpopup_item_cb, NULL);
    
20.         elm_ctxpopup_item_append(ctxpopup, "Item 3", NULL, ctxpopup_item_cb, NULL);
    
21.         elm_ctxpopup_direction_priority_set(ctxpopup, ELM_CTXPOPUP_DIRECTION_DOWN, ELM_CTXPOPUP_DIRECTION_UNKNOWN,
    
22.                         ELM_CTXPOPUP_DIRECTION_UNKNOWN, ELM_CTXPOPUP_DIRECTION_UNKNOWN);
    
23. 
    
24.         //change position
    
25.         Evas_Coord x, y;
    
26.         evas_pointer_canvas_xy_get(evas_object_evas_get(ad->win), &x, &y);
    
27.         evas_object_move(ctxpopup, x, y);
    
28.         
    
29.         evas_object_show(ctxpopup);
    
30. }
    
31. 
    
32. static void ctx_popup_test(appdata_s *ad) {
    
33.         Evas_Object *button;
    
34.         button = elm_button_add(ad->win);
    
35.         elm_object_text_set(button, "Show ctx popup");
    
36.         evas_object_smart_callback_add(button, "clicked", show_ctx_popup, ad);
    
37.         evas_object_resize(button, 480, 100);
    
38.         evas_object_show(button);
    
39. }
