"""
Edit a string, password, or integer
The TextEditor displays a Str, Password, or Int trait for the user to edit.
When editing a Str, consider styles 'simple' (one-line), 'custom' (multi-line),
or read-only (multi-line).
When editing a Password, use style 'simple' (shows asterisks).
When editing an Int, consider styles 'simple' and 'readonly'.
