|
* @brief Widget to display text, with simple html-like markup.
|
|
*
|
|
* The Label widget @b 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:
|
|
* @li default - No animation
|
|
* @li marker - Centers the text in the label and makes it bold by default
|
|
* @li 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).
|
|
* @li 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.
|
|
* @li 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 @ref 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
|
|
* @ref Layout:
|
|
* @li @c "language,changed": The program's language changed.
|
|
*
|
|
* See @ref tutorial_label for a demonstration of how to use a label widget.
