Widget description
|
|
------------------

.. image:: /images/flipselector-preview.png
|
|
:align: left
|
|
|
|
A flip selector is a widget to show a set of *text* items, one at a time, with
|
|
the same sheet switching style as the :py:class:`~efl.elementary.clock.Clock`
|
|
widget, when one changes the current displaying sheet (thus, the "flip" in the
|
|
name).
|
|
|
|
User clicks to flip sheets which are *held* for some time will
|
|
make the flip selector to flip continuously and automatically for
|
|
the user. The interval between flips will keep growing in time,
|
|
so that it helps the user to reach an item which is distant from
|
|
the current selection.
|
|
|
|
This widget emits the following signals, besides the ones sent from
|
|
:py:class:`~efl.elementary.layout_class.LayoutClass`:
|
|
|
|
- ``selected`` - when the widget's selected text item is changed
|
|
- ``overflowed`` - when the widget's current selection is changed
|
|
from the first item in its list to the last
|
|
- ``underflowed`` - when the widget's current selection is changed
|
|
from the last item in its list to the first
|
|
- ``focused`` - When the flipselector has received focus. (since 1.8)
|
|
- ``unfocused`` - When the flipselector has lost focus. (since 1.8)
|
|
|
|
Available styles for it:
|
|
|
|
- ``default``
|
|
|
|
Default text parts of the flipselector items that you can use for are:
|
|
|
|
- ``default`` - label of the flipselector item
