如何从 Tizen 表盘调用首选项屏幕（Tizen 原生）

Question

I am developing a watch face and want to include some preferences (with UI components like checkboxes, etc.) that the user can open by tapping on the watch face. For this, what is the proper way to open a preferences list? Is it possible to include the code for the preferences (genlist, sliders, etc.) in the watch face project? Or do I need to create a dedicated UI project which is then bundled with the watch face via the Multi Package function of Tizen Studio and launched from the watch face through the app manager (app_control_h)?

@go3d, I think you can use the entry component for the user text input. here is the document for the entry usages on the wearable device. ( https://docs.tizen.org/application/native/guides/ui/efl/wearable/component-entry/ ) I guess you can add some codes for the entry component to the WeatherWatch sample.

Example)

void maxlength_reached(void *data, Evas_Object *obj, void *event_info)
{
  //Implements the behavior when the entry maxlenth is reached.
}

static void _entry_enter_click(void *data, Evas_Object *obj, void *event_info)
{
  //Implements the behavior when the enter key is pressed.
}

// Create Entry Object.
Evas_Object* entry = elm_entry_add(layout);
elm_entry_single_line_set(entry, EINA_TRUE);
elm_entry_scrollable_set(entry, EINA_TRUE);
elm_scroller_policy_set(entry, ELM_SCROLLER_POLICY_OFF, ELM_SCROLLER_POLICY_AUTO);
evas_object_smart_callback_add(entry, "maxlength,reached", maxlength_reached, NULL);

limit_filter_data.max_char_count = 0;
limit_filter_data.max_byte_count = 100;
elm_entry_markup_filter_append(entry, elm_entry_filter_limit_size, &limit_filter_data);
elm_object_part_text_set(entry, "elm.guide", "input your text");
elm_entry_cursor_end_set(entry);
evas_object_size_hint_weight_set(entry, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);
evas_object_size_hint_align_set(entry, EVAS_HINT_FILL, EVAS_HINT_FILL);
evas_object_smart_callback_add(entry, "activated", _entry_enter_click, NULL);

elm_object_content_set(layout, entry);

Hi preferences (saving data), there are 2 ways:

1. https://tizenschool.org/tutorial/118/contents/10

2. use xamarin.essentials NuGet package and Preferences.Get(..)/Preferences.Set(..) methods
