""" | |
Parameters: | |
value: Default value to show in the code editor. If callable, the function will be called whenever the app loads to set the initial value of the component. | |
language: The language to display the code as. Supported languages listed in `gr.Code.languages`. | |
every: If `value` is a callable, run the function 'every' number of seconds while the client connection is open. Has no effect otherwise. The event can be accessed (e.g. to cancel it) via this component's .load_event attribute. | |
label: The label for this component. Appears above the component and is also used as the header if there are a table of examples for this component. If None and used in a `gr.Interface`, the label will be the name of the parameter this component is assigned to. | |
interactive: Whether user should be able to enter code or only view it. | |
show_label: if True, will display label. | |
container: If True, will place the component in a container - providing some extra padding around the border. | |
scale: relative size compared to adjacent Components. For example if Components A and B are in a Row, and A has scale=2, and B has scale=1, A will be twice as wide as B. Should be an integer. scale applies in Rows, and to top-level Components in Blocks where fill_height=True. | |
min_width: minimum pixel width, will wrap if not sufficient screen space to satisfy this value. If a certain scale value results in this Component being narrower than min_width, the min_width parameter will be respected first. | |
visible: If False, component will be hidden. | |
elem_id: An optional string that is assigned as the id of this component in the HTML DOM. Can be used for targeting CSS styles. | |
elem_classes: An optional list of strings that are assigned as the classes of this component in the HTML DOM. Can be used for targeting CSS styles. | |
render: If False, component will not render be rendered in the Blocks context. Should be used if the intention is to assign event listeners now but render the component later. | |
key: if assigned, will be used to assume identity across a re-render. Components that have the same key across a re-render will have their value preserved. | |
