Widget description
|
|
==================
|
|
|
|
A Hover object will hover over its ``parent`` object at the ``target``
|
|
location.
|
|
|
|
Anything in the background will be given a darker coloring to indicate
|
|
that the hover object is on top (at the default theme). When the hover
|
|
is clicked it is dismissed(hidden), if the contents of the hover are
|
|
clicked that **doesn't** cause the hover to be dismissed.
|
|
|
|
A Hover object has two parents. One parent that owns it during creation
|
|
and the other parent being the one over which the hover object spans.
|
|
|
|
|
|
Available styles
|
|
================
|
|
|
|
- default
|
|
- popout
|
|
- menu
|
|
- hoversel_vertical
|
|
|
|
|
|
Emitted signals
|
|
===============
|
|
|
|
- ``clicked`` - the user clicked the empty space in the hover to
|
|
dismiss.
|
|
- ``dismissed`` - the user clicked the empty space in the hover to dismiss.
|
|
(since 1.8)
|
|
- ``smart,changed`` - a content object placed under the "smart"
|
|
policy was replaced to a new slot direction.
|
|
|
|
|
|
Layout content parts
|
|
====================
|
|
|
|
- ``left``
|
|
- ``top-left``
|
|
- ``top``
|
|
- ``top-right``
|
|
- ``right``
|
|
- ``bottom-right``
|
|
- ``bottom``
|
|
- ``bottom-left``
|
|
- ``middle``
|
|
- ``smart``
|
|
|
|
All directions may have contents at the same time, except for "smart".
|
|
This is a special placement hint and its use case depends of the
|
|
calculations coming from :py:meth:`~Hover.best_content_location_get`. Its use
|
|
is for cases when one desires only one hover content, but with a dynamic
|
|
special placement within the hover area. The content's geometry,
|
|
whenever it changes, will be used to decide on a best location, not
|
|
extrapolating the hover's parent object view to show it in (still being
|
|
the hover's target determinant of its medium part -- move and resize it
|
|
to simulate finger sizes, for example). If one of the directions other
|
|
than "smart" are used, a previously content set using it will be
|
|
deleted, and vice-versa.
|
|
|
|
.. note:: The hover object will take up the entire space of ``target``
|
|
object.
|
|
|
|
.. note:: The content parts listed indicate the direction that the content
|
|
will be displayed
