双击事件在 Tizen 可穿戴设备中不起作用？为什么？

问题描述

我一直在尝试让双击工作，但由于某种原因，只有单击事件有效。我是否缺少某种库或参数？

typedef struct appdata {
    Evas_Object *win;
    Evas_Object *conform;
    Evas_Object *button;
} appdata_s;

    ad->button = elm_button_add(ad->conform);
    elm_object_text_set(ad->conform,"Hello Tizen");
    elm_object_style_set(ad->conform,"bottom");
    evas_object_size_hint_weight_set(ad->button,EVAS_HINT_EXPAND,EVAS_HINT_EXPAND);
    evas_object_smart_callback_add(ad->button,"clicked",test_single_click,ad->conform);
    evas_object_smart_callback_add(ad->button,"clicked,double",test_double_click,ad->conform);
    elm_object_content_set(ad->conform,ad->button);

static void
test_single_click(void *data,Evas_Object *obj,void *event_info)
{
   dlog_print(DLOG_INFO,LOG_TAG,"Button Clicked");
}
static void
test_double_click(void *data,"Button Clicked - Twice");
}

解决方法

按钮小部件不支持双击事件回调。

使用手势层获取更多信息的双击事件回调。
