News

v0.2.4

Adds support for customizing the message handler names for on change and on focus events emitted by the inputs. Under the hood this will generate a Message class with the appropriate name for Textual to send it to the handler name provided. You'll then want add the handler to the input's parent or the App instance. If you opt not to customize these handlers, their values will be the default handle_input_on_change and handle_input_on_focus. See examples/simple_form.py for a working example.

email = TextInput(name="email", title="Email")
email.on_change_handler_name = "handle_email_on_change"
email.on_focus_handler_name = "handle_email_on_focus"
