python - 触摸并影响任何物体

问题描述

...我怎样才能给出函数路径？我找不到如何解决寻址问题。有人知道如何解决这个问题吗？当我只点击绿色区域时，我想做白色区域按钮的操作。...

'''python main.py

解决方案

有点尴尬，但你可以通过添加一个这样的来做到这id一点Sec：

<Area>:
    size_hint: 1, 1
    pos_hint: {"x":0,"y":0}
    canvas:
        Color:
            rgba:0.9,0.9,0.9,1
        Rectangle:
            size:self.size    
    Sec:
        id: sec
    Vec:

然后在你的on_touch_down()in 中使用它Vec：

class Vec(RelativeLayout):
    """ This is green area
    I want the button to disable when the green area is clicked.
    """
    def on_touch_down(self,touch):
        if self.collide_point(*touch.pos):
            App.get_running_app().root.ids.sec.ids.secbut.disabled = True
