Default text for the button to display. If callable, the function will be called whenever the app loads to set the initial value of the component.
every

float | None

default: None

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.
variant

Literal[('primary', 'secondary', 'stop')]

default: "secondary"

'primary' for main call-to-action, 'secondary' for a more subdued style, 'stop' for a stop button.
size

Literal[('sm', 'lg')] | None

default: None

Size of the button. Can be "sm" or "lg".

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.
scale

int | None

default: None

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

int | None

default: None

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.

Description

Event listeners allow you to capture and respond to user interactions with the UI components you've defined in a Gradio Blocks app. When a user interacts with an element, such as changing a slider value or uploading an image, a function is called.

Supported Event Listeners

The ClearButton component supports the following event listeners. Each event listener takes the same parameters, which are listed in the Event Arguments table below.

Listener Description

ClearButton.add(fn, ···)

Adds a component or list of components to the list of components that will be cleared when the button is clicked.

ClearButton.click(fn, ···)

Triggered when the Button is clicked.
