kivy:使小部件对单击和双击的反应不同

问题描述

我检测到一个小部件上的双击，如 kivy 文档中所述.如何以一种好的方式实现单击和双击的不同反应?

I detect a double-tap on a widget like described in the kivy doc. How can i realize different reaction for single- and double-tap in a good way?

def on_touch_down(self, touch):
    if self.collide_point(*touch.pos):
        if touch.is_double_tap:
            print('here start function B (but not function A in advance!)')
        else:
            print('here start function A')
    return super(MyLabel, self).on_touch_down(touch)

推荐答案

我会看看这个:https://groups.google.com/forum/#!topic/kivy-users/slYzx9uZ39M看起来您可以设置一个点击等待期，等待在第一次点击后查看您是否要再次点击.希望这可以帮助.希望我知道更多:P

I would check this out: https://groups.google.com/forum/#!topic/kivy-users/slYzx9uZ39M it looks like you can set a tap wait period where it waits to see if you are going to tap again after the first tap. Hope this helps. Wish I knew more :P
