Flipselector

The flipselector UI component has a set of text items and a selector that flips up or down to change the text on it. For more information, see the Flipselector API.

This feature is supported in mobile applications only.

Basic Usage

To use a flipselector component in your application:

  1. Add a flipselector with the elm_flipselector_add() function:

    Evas_Object *flipselector;

flipselector = elm_flipselector_add(parent);

  2. Add items to the flipselector with the elm_flipselector_item_append() function:

    Elm_Object_Item *flip_it;

flip_it = elm_flipselector_item_append(flipselector, "99", it_select_cb, NULL);

/* Called when the flip_it object is selected */
void
it_select_cb(void *data, Evas_Object *obj, void *event_info)
{
    dlog_print(DLOG_INFO, LOG_TAG, "flip_it selected\n");
}

  3. Register the callback functions.

    The following example shows how to define and register a callback for the selected signal:

    evas_object_smart_callback_add(flipselector, "selected", _flip_selected_cb, NULL);

static void
_flip_selected_cb(void *data, Evas_Object *obj, void *event_info)
{
    Elm_Object_Item *flip_it = event_info;

    /* Code that does the desired action */
}

The following example shows a simple use case of the flipselector component.

Example: Flipselector use case

Flipselector

Evas_Object *win;
Evas_Object *conf;
Evas_Object *nf;
Evas_Object *flipselector;
char buf[8];
int i;

/* Starting right after the basic EFL UI layout code */
/* win - conformant - naviframe */

/* Add a flipselector */
flipselector = elm_flipselector_add(nf);

for (i = 0; i <= 99; i++) {
    snprintf(buf, 8, "%u", i);
    elm_flipselector_item_append(flipselector, buf, flipselector_item_select_cb, NULL);
}
elm_naviframe_item_push(nf, "Flipselector", NULL, NULL, flipselector, NULL);

void
flipselector_item_select_cb(void *data, Evas_Object *obj, void *event_info)
{
    Elm_Object_Item *it = event_info;
    printf("label of selected item is: %s\n", elm_object_item_text_get(it));
}

Options

To set the flipselector options:

  • First interval

    You can define the length of the first change interval when the user keeps the mouse button down for a longer period. After the first interval, the flipselector text is changed regularly while the mouse button remains down.

    To set the first interval, use the elm_flipselector_first_interval_set() function:

    elm_flipselector_first_interval_set(flipselector, 2.0);

  • Flipselector value

    To change the value:

    • Show the next text using the elm_flipselector_flip_next() function:

      elm_flipselector_flip_next(flipselector);

    • Show the previous text using the elm_flipselector_flip_prev() function:

      elm_flipselector_flip_prev(flipselector);

    • Show the text of the specific item using the elm_flipselector_item_selected_set() function.

      If the second parameter is set to EINA_FALSE, the flipselector shows the text of the first item.

      elm_flipselector_item_selected_set(flip_it, EINA_TRUE);

Callbacks

You can register callback functions connected to the following signals for a flipselector object.

Table: Flipselector callback signals

Signal Description event_info
selected The flipselector’s selected text item changes. NULL
overflowed The flipselector’s current selection changes from the first item to the last one. NULL
underflowed The flipselector’s current selection changes from the last item to the first one. NULL

Note

The signal list in the API reference can be more extensive, but only the above signals are actually supported in Tizen.
