Usage
|
|
-----
|
|
|
|
.. code-block:: python
|
|
|
|
self.add_widget(
|
|
MDExpansionPanel(
|
|
icon="logo.png", # panel icon
|
|
content=Content(), # panel content
|
|
panel_cls=MDExpansionPanelOneLine(text="Secondary text"), # panel class
|
|
)
|
|
)
|
|
|
|
To use :class:`~MDExpansionPanel` you must pass one of the following classes
|
|
to the :attr:`~MDExpansionPanel.panel_cls` parameter:
|
|
|
|
- :class:`~MDExpansionPanelOneLine`
|
|
- :class:`~MDExpansionPanelTwoLine`
|
|
- :class:`~MDExpansionPanelThreeLine`
|
|
|
|
These classes are inherited from the following classes:
|
|
|
|
- :class:`~kivymd.uix.list.OneLineAvatarIconListItem`
|
|
- :class:`~kivymd.uix.list.TwoLineAvatarIconListItem`
|
|
- :class:`~kivymd.uix.list.ThreeLineAvatarIconListItem`
|
|
|
|
.. code-block:: python
|
|
|
|
self.root.ids.box.add_widget(
|
|
MDExpansionPanel(
|
|
icon="logo.png",
|
|
content=Content(),
|
|
panel_cls=MDExpansionPanelThreeLine(
|
|
text="Text",
|

secondary_text="Secondary text",
