|
|
.. rubric:: Magical effects for buttons.
|
|
|
|
.. warning:: Magic effects do not work correctly with `KivyMD` buttons!
|
|
|
|
To apply magic effects, you must create a new class that is inherited from the
|
|
widget to which you apply the effect and from the :attr:`MagicBehavior` class.
|
|
|
|
In `KV file`:
|
|
|
|
.. code-block:: kv
|
|
|
|
<MagicButton@MagicBehavior+MDRectangleFlatButton>
|
|
|
|
In `python file`:
|
|
|
|
.. code-block:: python
|
|
|
|
class MagicButton(MagicBehavior, MDRectangleFlatButton):
|
|
pass
|
|
|
|
.. rubric:: The :attr:`MagicBehavior` class provides five effects:
|
|
|
|
- :attr:`MagicBehavior.wobble`
|
|
- :attr:`MagicBehavior.grow`
|
|
- :attr:`MagicBehavior.shake`
|
|
- :attr:`MagicBehavior.twist`
|
|
- :attr:`MagicBehavior.shrink`
|
|
|
|

|
|
|
|
.. code-block:: python
