Tizen Native API  5.5

Widget to display text, with simple html-like markup.

label_inheritance_tree.png

The Label widget doesn't allow text to overflow its boundaries, if the text doesn't fit the geometry of the label it will be ellipsized or be cut. Elementary provides several styles for this widget:

  • default - No animation
  • marker - Centers the text in the label and makes it bold by default
  • slide_long - The entire 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.

Custom themes can of course invent new markup tags and style them any way they like.

This widget inherits from the Layout one, so that all the functions acting on it also work for label objects.

This widget emits the following signals, besides the ones sent from Layout:

  • "language,changed": The program's language changed.
  • "slide,end": The slide is end.

See Label example for a demonstration of how to use a label widget.

Eina_Bool elm_label_ellipsis_get ( const Elm_Label *  obj)

Control the ellipsis behavior of the label.

If set to true and the text doesn't fit in the label an ellipsis("...") will be shown at the end of the widget.

Warning This doesn't work with slide(elm_label_slide_set()) or if the chosen wrap method was ELM_WRAP_WORD.

Parameters:
[in]objThe object.
Returns:
To ellipsis text or not
Since :
2.3
void elm_label_ellipsis_set ( Elm_Label *  obj,

double elm_label_slide_duration_get ( const Elm_Label *  obj)

Control the slide duration of the label.

Note:
If you set the speed of the slide using elm_label_slide_speed_set you cannot get the correct duration using this function until the label is actually rendered and resized.
Parameters:
[in]objThe object.
Returns:
The duration in seconds in moving text from slide begin position to slide end position
Since :
