PropertySheet

Initialization

name	type	default	description
value	typing.Optional[typing.Any][Any, None]	None	The initial dataclass instance to render.
label	str | None	None	The main label for the component, displayed in the accordion header.
root_label	str	"General"	The label for the root group of properties.
show_group_name_only_one	bool	True	If True, only the group name is shown when there is a single group.
disable_accordion	bool	False	If True, disables the accordion functionality.
visible	bool	True	If False, the component will be hidden.
open	bool	True	If False, the accordion will be collapsed by default.
elem_id	str | None	None	An optional string that is assigned as the id of this component in the DOM.
scale	int | None	None	The relative size of the component in its container.
width	int | str | None	None	The width of the component in pixels.
height	int | str | None	None	The maximum height of the component's content area in pixels before scrolling.
min_width	int | None	None	The minimum width of the component in pixels.
container	bool	True	If True, wraps the component in a container with a background.
elem_classes	list[str] | str | None	None	An optional list of strings that are assigned as the classes of this component in the DOM.

Events

name	description
change	Triggered when the value of the PropertySheet changes either because of user input (e.g. a user types in a textbox) OR because of a function update (e.g. an image receives a value from the output of an event trigger). See .input() for a listener that is only triggered by user input.
input	This listener is triggered when the user changes the value of the PropertySheet.
expand	This listener is triggered when the PropertySheet is expanded.
collapse	This listener is triggered when the PropertySheet is collapsed.
undo	This listener is triggered when the user clicks the undo button in component.

User function

The impact on the users predict function varies depending on whether the component is used as an input or output for an event (or both).

• When used as an Input, the component only impacts the input signature of the user function.
• When used as an output, the component only impacts the return signature of the user function.

The code snippet below is accurate in cases where the component is used as both an input and an output.

• As output: Is passed, a new, updated instance of the dataclass.
• As input: Should return, the dataclass instance to process.

def predict(
    value: Any
) -> Any:
    return value
