:meth:`on_quad_touch`. :meth:`on_quad_touch`.
.. warning::
When changing the a :class:`TextInput` parameter that requires
re-drawing, e.g. modifying :attr:`text`, the updates occur on the next
clock cycle and not instantly. This might cause any changes to the
:class:`TextInput` that occur between the modification and the next
cycle to be ignored, or to use the previous values. For example, after
a update to :attr:`text`, changing the cursor in the same clock frame
will move it using the previous text and will likely end up in a
incorrect position. The solution is to schedule any updates to occur
on the next clock cycle using e.g.
:meth:`~kivy.clock.ClockBase.schedule_once`.
