Question

我的EDC布局文件中有一个文本字段，我希望在按钮点击时获取该数据。我对此一无所知。那么，有人会帮助我吗？

代码来自布局和按钮examples。以下是其他语言绑定的示例（c，c ++，js）。

按钮和布局（原生）的相应Tizen documentation。

.edc布局文件，其中包含文本部分"title"和占位符/ SWALLOW部分"placerholder"以放置按钮。

collections {
   group {
      name: "example/mylayout";
      data {
         item: "title" "Layout Example 01";
      }

      parts {
         part {
            name: "example/title";
            type: TEXT;

            description {
               state: "default" 0.0;
               color: 0 0 0 255;
               rel1 {
                  relative: 0.0 0.0;
                  offset: 0 0;
               }
               rel2 {
                  relative: 1.0 0.5;
                  offset: -1 -1;
               }
               text {
                  text: "bla";
                  size: 16;
                  font: "sans";
                  min: 1 1;
                  ellipsis: -1;
               }
            }
         }
         part {
            name: "placleholder";
            type: SWALLOW;

            description {
               state: "default" 0.0;
               fixed: 1 1;

               rel1 {
                  relative: 0.0 0.5;
                  offset: 0 0;
               }
               rel2 {
                  relative: 1.0 1.0;
                  offset: -1 -1;
               }
            }
         }
    } 
}

要设置布局，请添加一个按钮，然后阅读旧版C中"title"部分的文本，如下所示（不是完整的工作示例，因为我无法测试）：

设置布局：

Evas_Object *win, *bt, *layout;

   // Create a window ( I don't know if this works in tizen like this.)
   win = elm_win_util_standard_add("layout", "Layout");
   elm_win_autodel_set(win, EINA_TRUE);

   // Adding layout and make it fill the window
   layout = elm_layout_add(win);
   evas_object_size_hint_weight_set(layout, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);
   elm_win_resize_object_add(win, layout);

   elm_layout_file_set(layout, "/path/to/layoutfile.edj", "example/mylayout");
   evas_object_show(layout);

添加按钮：

   bt = elm_button_add(layout);
   elm_object_text_set(bt, "Get the text");

   // put the button into the layout
   elm_object_part_content_set(layout, "placeholder", bt);

   // add clicked callback to button, pass the layout reference as data pointer
   evas_object_smart_callback_add(bt, "clicked", _btn_cb, layout);

按钮回调：

static void
_btn_cb(void *data, Evas_Object *btn EINA_UNUSED, void *event_info EINA_UNUSED)
{
   // data pointer is the layout reference
   Evas_Object *layout = data;

   // with the layout reference we can get the text of part "title"
   const char *text = elm_object_part_text_get(layout, "title");
}
