Tab/Enter (and other keystrokes) handling in Kivy's TextInput widgets

Question

I\'m writing an app using Kivy framework and I stumbled upon a minor but annoying problem: I don\'t know how to handle Tab/Enter/Arrow keys in text fields so that press

Answer 1

Kivy 1.9 provides the ability to set write_tab: False on text inputs (see docs), causing the tab key to focus on the next focusable widget.

Kivy allows the Enter key to dispatch events by setting multiline: False and on_text_validate: root.foo().

So, to create a text input widget that has the desired Enter and Tab functionality, do as follows:

TextInput:
    write_tab: False
    multiline: False
    on_text_validate: root.foo()
