Widget description
------------------

This is a button that, when clicked, creates an Elementary window (or
inner window) with a :py:class:`~efl.elementary.fileselector.Fileselector`
within.

When a file is chosen, the (inner) window is closed and the button emits
a signal having the selected file as it's ``event_info``.

This widget encapsulates operations on its internal file selector on its
own API. There is less control over its file selector than that one
would have instantiating one directly.

The following styles are available for this button:

- ``default``
- ``anchor``
- ``hoversel_vertical``
- ``hoversel_vertical_entry``

This widget emits the following signals, besides the ones sent from
:py:class:`~efl.elementary.button.Button`:

- ``file,chosen`` - the user has selected a path which comes as the
  ``event_info`` data
- ``language,changed`` - the program's language changed

Default text parts of the fileselector_button widget that you can use for
are:

- ``default`` - Label of the fileselector_button

Default content parts of the fileselector_button widget that you can use
for are:

- ``icon`` - Icon of the fileselector_button

Fileselector Interface
======================

This widget supports the fileselector interface.

If you wish to control the fileselector part using these functions,
inherit both the widget class and the
:py:class:`~efl.elementary.fileselector.Fileselector` class
using multiple inheritance, for example::

    class CustomFileselectorButton(Fileselector, FileselectorButton):
        def __init__(self, canvas, *args, **kwargs):
            FileselectorButton.__init__(self, canvas)
