Widget description
|
|
------------------
|
|
|
|
.. image:: /images/check-preview.png
|
|
:align: left
|
|
|
|
The check widget allows for toggling a value between true and false.
|
|
|
|
Check objects are a lot like radio objects in layout and functionality,
|
|
except they do not work as a group, but independently, and only toggle
|
|
the value of a boolean :py:attr:`~Check.state` between false and true.
|
|
|
|
This widget emits the following signals, besides the ones sent from
|
|
:py:class:`~efl.elementary.layout_class.LayoutClass`:
|
|
|
|
- ``changed`` - This is called whenever the user changes the state of
|
|
the check objects.
|
|
- ``focused`` - When the check has received focus. (since 1.8)
|
|
- ``unfocused`` - When the check has lost focus. (since 1.8)
|
|
|
|
Default content parts of the check widget that you can use for are:
|
|
|
|
- ``icon`` - An icon of the check
|
|
|
|
Default text parts of the check widget that you can use for are:
|
|
|
|
- ``default`` - A label of the check
|
|
- ``on`` - On state label of the check
|
|
- ``off`` - Off state label of the check
