NumPad popup when selecting TextInput app yields TypeError: object.__init__() takes no parameters

[Griffo]

I just have a simple tabbed panel with a TextInput object which when clicked should open up a numpad screen which should populate TextInput once enter is clicked. This did work in Kivy 1.90 by my memory though I've heard some new changes have changed the way arguments are inherited.

main.py

from kivy.uix.floatlayout import FloatLayout

from kivy.uix.button import Button

from kivy.uix.textinput import TextInput

class ValveInput(TextInput):

    def __init__(self, **kwargs):

        super(ValveInput, self).__init__(**kwargs)

    def my_callback(instance):

        self.text = num_pad.ids.num_label.text

        self.popup.dismiss()

    def on_touch_down(self, touch):

        if self.collide_point(touch.x, touch.y):

            prompt_content = BoxLayout(orientation='vertical')      # Main layout

            num_pad = ValveNumWidget()

            prompt_content.add_widget(num_pad)

            self.popup = Popup(id='num_pad_popup', title='Enter value', content=prompt_content, autodismiss=False)

            num_pad.ids.enter_btn.bind(on_press=my_callback)

            # Open the pop-up:

            self.popup.open()

class RootWidget(FloatLayout):

    def __init__(self):

        super(RootWidget, self).__init__()

        self.button = ValveInput(id='valve_input',text='',values=('0', '1','2','3','4','5'))

        home_window = TabbedPanelItem(text="Pumps")

        home_window.add_widget(self.button)

        main_window = TabbedPanel(do_default_tab=False)

        main_window.add_widget(home_window)

        self.add_widget(main_window)

    def button_clicked(self, button):

        print(self.button.text)

                    NumPadButton:

                        id: enter_btn

                        text: 'Enter'

Any help appreciated -- I'm fairly sure it is a quick fix but unsure how to proceed.

Apologies; I was missing a few pieces. Here is the update code and I'm fairly sure my issue revolved around how I pass kwargs in this part.

def __init__(self, **kwargs):

        super(ValveInput, self).__init__(**kwargs)

from kivy.app import App

from kivy.uix.floatlayout import FloatLayout

from kivy.uix.boxlayout import BoxLayout

from kivy.uix.button import Button

from kivy.uix.widget import Widget

from kivy.uix.tabbedpanel import TabbedPanel,TabbedPanelItem

from kivy.uix.textinput import TextInput

from kivy.uix.popup import Popup

class ValveNumWidget(FloatLayout):

    pass

Probably auto_dismiss again?

[Griffo]

Indeed - I guess I need to check that the arguments being passed are permissible. 

Apologies for not seeing this earlier -- it works by removing that argument.
