EventData

gradio.EventData(···)

Description

When gr.EventData or one of its subclasses is added as a type hint to an argument of a prediction function, a gr.EventData object will automatically be passed as the value of that argument. The attributes of this object contains information about the event that triggered the listener. The gr.EventData object itself contains a .target attribute that refers to the component that triggered the event, while subclasses of gr.EventData contains additional attributes that are different for each class.

with gr.Blocks() as demo:
    table = gr.Dataframe([[1, 2, 3], [4, 5, 6]])
    gallery = gr.Gallery([("cat.jpg", "Cat"), ("dog.jpg", "Dog")])
    textbox = gr.Textbox("Hello World!")
    statement = gr.Textbox()

    def on_select(value, evt: gr.EventData):
        return f"The {evt.target} component was selected, and its value was {value}."

    table.select(on_select, table, statement)
