Event Listeners

Description

Event listeners allow you to 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 Textbox component supports the following event listeners. Each event listener takes the same parameters, which are listed in the Event Parameters table below.

Listener	Description
`Textbox.change(fn, ···)`	Triggered when the value of the Textbox 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.
`Textbox.input(fn, ···)`	This listener is triggered when the user changes the value of the Textbox.
`Textbox.select(fn, ···)`	Event listener for when the user selects or deselects the Textbox. Uses event data gradio.SelectData to carry `value` referring to the label of the Textbox, and `selected` to refer to state of the Textbox. See EventData documentation on how to use this event data
`Textbox.submit(fn, ···)`	This listener is triggered when the user presses the Enter key while the Textbox is focused.
`Textbox.focus(fn, ···)`	This listener is triggered when the Textbox is focused.
`Textbox.blur(fn, ···)`	This listener is triggered when the Textbox is unfocused/blurred.
