.. rubric:: Widget description
|

|
|
.. image:: /images/label-preview.png
|
|
|
|
|
|
Widget to display text, with simple html-like markup.
|
|
|
|
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 emits the following signals, besides the ones sent from
|
|
:py:class:`elementary.layout.Layout`:
|
|
|
|
- *"language,changed"*: The program's language changed.
