How to change vanilla.EditText value with arrows

There is a way change value of vanilla.EditText by pressing up/down arrow ?
Does this have anything to do with the .formatter?

from vanilla import Window, EditText
class EditTextDemo:

    def __init__(self):
        self.w = Window((120, 42))
        self.w.editText = EditText((10, 10, -10, 22), text='0')



I would advise building this kind of stuff directly in XCode. Then you don’t have to work with hacking a wrapper in the first place :wink:
