I defined a Kivy Button and associated a method with on_touch_up. However, when I click the button, the method is called twice. This issue stops occurring if I also define on_touch_down and return True when touch.button == "left". Both on_touch_up and on_touch_down are filtered to handle only the left mouse button. What I did seems to solve the problem, but I'm not sure if it's the correct or recommended approach. I would like to know: Is this the right way to handle this situation? Is there a better or more idiomatic approach in Kivy? Here is the code: class MyButton(Button): def on_touch_up(self, touch): if self.collide_point(*touch.pos): if touch.button == 'left': self.left_released() return True return super().on_touch_up(touch) def on_touch_down(self, touch): # I tried this without knowing if it's the right way if self.collide_point(*touch.pos): if touch.button == 'left': return True return super().on_touch_down(touch) Continue reading...
