from kivy.app import App

from kivy.uix.widget import Widget

from kivy.uix.button import Button

from kivy.uix.boxlayout import BoxLayout

from kivy.properties import ListProperty

from kivy.event import EventDispatcher

class RootWidget(BoxLayout):

 def __init__(self, **kwargs):

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

     self.add_widget(Button(text='btn 1'))

     cb = CustomBtn()

     cb.bind(on_test=self.btn_pressed)

     self.add_widget(cb)

     self.add_widget(Button(text='btn 2'))

 def btn_pressed(self, *arg):

     print ('clicked ',arg)

class CustomBtn(Widget):

def __init__(self, **kwargs):

super().__init__(**kwargs)

self.register_event_type('on_test')

def on_touch_up(self, touch):

if self.collide_point(*touch.pos):

self.dispatch('on_test')

return True

return super(CustomBtn, self).on_touch_down(touch)

def on_test(self, *arg):pass

class TestApp(App):

 def build(self):

     return RootWidget()

if __name__ == '__main__':

 TestApp().run()

You could do something like this… but doing it with the bind is correct.

 

from kivy.app import App
from kivy.uix.widget import Widget
from kivy.uix.button import Button
from kivy.uix.boxlayout import BoxLayout

from kivy.properties import ObjectProperty

class RootWidget(BoxLayout):

    def __init__(self, **kwargs):
        super(RootWidget, self).__init__(**kwargs)
        self.add_widget(Button(text='btn 1'

))
        cb = CustomBtn(touch_action=self.btn_pressed)
        # cb.bind(on_test=self.btn_pressed)
        self.add_widget(cb)
        self.add_widget(Button(text='btn 2'))

    def btn_pressed(self, *arg):
        print('clicked ', *arg)


class CustomBtn(Widget):
    touch_action = ObjectProperty(None, allownone=True)

    def __init__(self, **kwargs):
        super().__init__(**kwargs)
        self.register_event_type('on_test')

    def on_touch_up(self, touch):
        if self.collide_point(*touch.pos):
            self.dispatch('on_test')
            return True
        return super(CustomBtn, self).on_touch_down(touch)

    def on_test(self, *args):
        print('on_test fired')
        if self.touch_action:
            self.touch_action(*args)
