more detailed explanation on the values.
`fullscreen`: str, one of ('0', '1', 'auto', 'fake')
Make the window fullscreen. Check the
:mod:`~kivy.config` documentation for a
more detailed explanation on the values.
`width`: int
Width of the window.
`height`: int
Height of the window.
`minimum_width`: int
Minimum width of the window (only works for sdl2 window provider).
`minimum_height`: int
Minimum height of the window (only works for sdl2 window provider).
`allow_screensaver`: bool
Allow the device to show a screen saver, or to go to sleep
on mobile devices. Defaults to True. Only works for sdl2 window
provider.
:Events:
`on_motion`: etype, motionevent
Fired when a new :class:`~kivy.input.motionevent.MotionEvent` is

`on_touch_down`:
Fired when a new touch event is initiated.
`on_touch_move`:
Fired when an existing touch event changes location.
`on_touch_up`:
Fired when an existing touch event is terminated.

Fired when the :class:`Window` GL surface is being flipped.
`on_rotate`: rotation
Fired when the :class:`Window` is being rotated.
`on_close`:
Fired when the :class:`Window` is closed.
`on_request_close`:
Fired when the event loop wants to close the window, or if the
escape key is pressed and `exit_on_escape` is `True`. If a function
bound to this event returns `True`, the window will not be closed.
If the the event is triggered because of the keyboard escape key,
the keyword argument `source` is dispatched along with a value of
`keyboard` to the bound functions.

A widget can request the keyboard, indicating a callback to call
when the keyboard is released (or taken by another widget).

`callback`: func
Callback that will be called when the keyboard is
closed. This can be because somebody else requested the
keyboard or the user closed it.
`target`: Widget
Attach the keyboard to the specified `target`. This should be
the widget that requested the keyboard. Ensure you have a
different target attached to each keyboard if you're working in
a multi user mode.
.. versionadded:: 1.0.8
`input_type`: string
Choose the type of soft keyboard to request. Can be one of
'text', 'number', 'url', 'mail', 'datetime', 'tel', 'address'.
.. note::
`input_type` is currently only honored on mobile devices.
.. versionadded:: 1.8.0
