I would like you to check my sample code for touch_began() method.

Thanks to your support, I understood how to set touch_began() to a pyui file.
Although I could set a method to a whole UI. I would like to set touch_began() to a specifed object like a button on the UI. Could you please tell me how?

My sample code is following.
In pyui file, I set “MyView” to Custom View Class via design tool. As a result, when I touched somewhere on the screen, “touch”, “move” and “end” messages were displayed in a console.
I would like to set a method to supecified button. Do I need to set something to CUSTOM ATTRIBUTES for a object?

import ui

class MyView (ui.View):

def touch_began(self, touch):
    # Called when a touch begins.
    print('touch')
def touch_moved(self, touch):
    # Called when a touch moves.
    print('move')
def touch_ended(self, touch):
    # Called when a touch ends.
    print('end')

v2= ui.load_view('touch_sample')
v2.present('sheet')
