VKeyboard
=========
.. image:: images/vkeyboard.jpg
:align: right
.. versionadded:: 1.0.8
VKeyboard is an onscreen keyboard for Kivy. Its operation is intended to be
transparent to the user. Using the widget directly is NOT recommended. Read the
section `Request keyboard`_ first.
Modes
-----
This virtual keyboard has a docked and free mode:
* docked mode (:attr:`VKeyboard.docked` = True)
Generally used when only one person is using the computer, like a tablet or
personal computer etc.
* free mode: (:attr:`VKeyboard.docked` = False)
Mostly for multitouch surfaces. This mode allows multiple virtual
keyboards to be used on the screen.
If the docked mode changes, you need to manually call
:meth:`VKeyboard.setup_mode` otherwise the change will have no impact.
During that call, the VKeyboard, implemented on top of a
:class:`~kivy.uix.scatter.Scatter`, will change the
behavior of the scatter and position the keyboard near the target (if target
and docked mode is set).
Layouts
-------
The virtual keyboard is able to load a custom layout. If you create a new
layout and put the JSON in :file:`<kivy_data_dir>/keyboards/<layoutid>.json`,
you can load it by setting :attr:`VKeyboard.layout` to your layoutid.
The JSON must be structured like this::
{
"title": "Title of your layout",
"description": "Description of your layout",
"cols": 15,
"rows": 5,
...
}
Then, you need to describe the keys in each row, for either a "normal",
"shift" or a "special" (added in version 1.9.0) mode. Keys for this row
data must be named `normal_<row>`, `shift_<row>` and `special_<row>`.
Replace `row` with the row number.
Inside each row, you will describe the key. A key is a 4 element list in
the format::
[ <text displayed on the keyboard>, <text to put when the key is pressed>,
<text that represents the keycode>, <size of cols> ]
Here are example keys::
# f key
["f", "f", "f", 1]
# capslock
["\u21B9", "\t", "tab", 1.5]
Finally, complete the JSON::
{
...
"normal_1": [
["`", "`", "`", 1], ["1", "1", "1", 1], ["2", "2", "2", 1],
["3", "3", "3", 1], ["4", "4", "4", 1], ["5", "5", "5", 1],
["6", "6", "6", 1], ["7", "7", "7", 1], ["8", "8", "8", 1],
["9", "9", "9", 1], ["0", "0", "0", 1], ["+", "+", "+", 1],
["=", "=", "=", 1], ["\u232b", null, "backspace", 2]
],
"shift_1": [ ... ],
"normal_2": [ ... ],
"special_2": [ ... ],
...
}
Request Keyboard
----------------
The instantiation of the virtual keyboard is controlled by the configuration.
Check `keyboard_mode` and `keyboard_layout` in the :doc:`api-kivy.config`.
If you intend to create a widget that requires a keyboard, do not use the
virtual keyboard directly, but prefer to use the best method available on
the platform. Check the :meth:`~kivy.core.window.WindowBase.request_keyboard`
method in the :doc:`api-kivy.core.window`.
If you want a specific layout when you request the keyboard, you should write
something like this (from 1.8.0, numeric.json can be in the same directory as
your main.py)::
keyboard = Window.request_keyboard(
self._keyboard_close, self)
if keyboard.widget:
vkeyboard = self._keyboard.widget
vkeyboard.layout = 'numeric.json'
