Displaying a List in a Popup Window in Tizen Native Application

Question

I'm trying to display a standard list (not a Genlist) within a popup window in my Tizen native application. Despite trying various combinations, I can't get the list to display properly - only the popup title appears.

Here's my current implementation:

void create_popup(void *data, Evas_Object *obj, void *event_info) {
    Evas_Object *list;
    Evas_Object *parent = obj;

    /* Create the popup */
    Evas_Object *popup = elm_popup_add(parent);
    elm_popup_align_set(popup, ELM_NOTIFY_ALIGN_FILL, 1.0);
    evas_object_size_hint_weight_set(popup, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);
    elm_object_part_text_set(popup, "title,text", "Title");
    elm_popup_orient_set(popup, ELM_POPUP_ORIENT_CENTER);

    list = elm_list_add(popup);
    elm_list_mode_set(list, ELM_LIST_COMPRESS);
    evas_object_size_hint_weight_set(list, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);
    evas_object_size_hint_align_set(list, EVAS_HINT_FILL, EVAS_HINT_FILL);
    
    char tmpString[16];
    sprintf(tmpString, "Reset Game");
    dlog_print(DLOG_INFO, APP_TAG, tmpString);
    elm_list_item_append(list, tmpString, NULL, NULL, NULL, NULL);
    elm_list_item_append(list, tmpString, NULL, NULL, NULL, NULL);

    /* Register the Back key event callback */
    eext_object_event_callback_add(popup, EEXT_CALLBACK_BACK, eext_popup_back_cb, NULL);
    /* Show the popup */
    elm_object_content_set(popup, list);
    evas_object_show(popup);
}

I've tried several approaches without success:

Adding a layout and placing the list within it
Creating the list with the parent instead of the popup
Removing all style settings

My goal is to create a menu when the menu button is pressed, similar to the example in the Tizen documentation.

Answer

Problem Understanding

The issue occurs when trying to display a standard list (elm_list) within a popup window. While the popup title appears correctly, the list items remain invisible. This is caused by incorrect list mode configuration.

Solution Methods

The primary solution is to change the list mode from ELM_LIST_COMPRESS to ELM_LIST_EXPAND
Ensure proper size hints are set for both the popup and list
Verify the list items are properly appended before setting the content

Code Examples

Here's the corrected implementation:

list = elm_list_add(popup);
/* Change this line from COMPRESS to EXPAND */
elm_list_mode_set(list, ELM_LIST_EXPAND);
evas_object_size_hint_weight_set(list, EVAS_HINT_EXPAND, EVAS_HINT_EXPAND);
evas_object_size_hint_align_set(list, EVAS_HINT_FILL, EVAS_HINT_FILL);

/* Add list items */
elm_list_item_append(list, "Reset Game", NULL, NULL, NULL, NULL);
elm_list_item_append(list, "Other Option", NULL, NULL, NULL, NULL);

/* Set list as popup content */
elm_object_content_set(popup, list);

Additional Tips

Always check the EFL documentation for proper widget configuration
When working with popups, ensure all child elements have proper size hints
For more complex menu structures, consider using Elm_Genlist instead of basic lists
Test your UI on different device resolutions
