The label UI component displays texts with a simple HTML-like markup. For more information, see the Label API.

This feature is supported in mobile applications only.

Basic Usage

To use a label component in your application:

  1. Add a label with the elm_label_add() function:

    Evas_Object *label;
    label = elm_label_add(parent);
  2. Set a text to the label with the elm_object_text_set() function. Label is based on textblock, which means you can use textblock markup in a label text.
    elm_object_text_set(label, "This is a label.");
  3. Register the callback functions.

    The following example shows how to define and register a callback for the slide,end signal:

    evas_object_smart_callback_add(label, "slide,end", slide_end_cb, data);
    slide_end_cb(void *data, Evas_Object *obj, void *event_info)
        dlog_print(DLOG_INFO, LOG_TAG, "Slide has reach the end.\n");

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

Example: Label use case


Evas_Object *win;
Evas_Object *conf;
Evas_Object *nf;
Evas_Object *box;
Evas_Object *label;

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

/* Add a box to pack a label */
box = elm_box_add(nf);
elm_object_content_set(nf, box);
elm_naviframe_item_push(nf, "Label", NULL, NULL, box, NULL);

label = elm_label_add(box);
elm_object_text_set(label, "This is a label");
elm_box_pack_end(box, label);


If you use a slide-type style, you can adjust the slide mode and animation duration using the following functions:

elm_label_slide_mode_set(label, ELM_LABEL_SLIDE_MODE_ALWAYS);
elm_label_slide_duration_set(label, 3);

The following table lists the available component styles.

Table: Label styles

Style Description
default No animation is used.
marker The text is centered and bolded.
slide_long The text appears from the right of the screen and slides until it disappears in the left of the screen (reappearing on the right again).
slide_short The text appears in the left of the label and slides to the right to show the overflow. When all of the text has been shown, the position is reset.
slide_bounce The text appears in the left of the label and slides to the right to show the overflow. When all of the text has been shown, the animation reverses, moving the text to the left.


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

Table: Label callback signals

Signal Description event_info
language,changed The program language changes. NULL
slide,end The slide reaches the end. NULL
anchor,clicked The anchor is clicked. Elm_Label_Anchor_Info object
anchor,mouse,down The anchor is pressed by mouse down. Elm_Label_Anchor_Info object
anchor,mouse,up The anchor is released by mouse up. Elm_Label_Anchor_Info object
Note The signal list in the API reference can be more extensive, but only the above signals are actually supported in Tizen.
