Question

我要创建它，因此单击此窗口小部件时不会单击它后面的窗口小部件，而仍然可以单击该父窗口小部件的子窗口小部件。每当我添加一些东西来终止事件时，单击它就不会在“内容”窗口小部件的子项上注册点击。如果我没有鼠标，那么它会在鼠标被覆盖或没有覆盖的所有内容上单击。这是我制作的可调整大小的子窗口的代码：

class SubWindow(Widget):
tPosRel = ListProperty()
bColor = ListProperty()
innerColor = ListProperty()
buttonPos = ListProperty()
innerPos = ListProperty()
innerSize = ListProperty()

    self.innerPos = (self.pos[0] + 5, self.pos[1] + 40)
    self.innerSize = (90, 265)
    self.innerColor = (.2, .2, .2, 1)
    self.bColor = (0, 0, 0, 1)
    brightnessAvg = (self.bColor[0] + self.bColor[1] + self.bColor[2])/3.0
    if brightnessAvg > .5:
        self.innerColor = (kwargs["bColor"][0] - .2, kwargs["bColor"][1] - .2, kwargs["bColor"][2] - .2, 1)
    else:
        self.innerColor = (kwargs["bColor"][0] + .2, kwargs["bColor"][1] + .2, kwargs["bColor"][2] + .2, 1)
    #print(self.innerColor)
    self.buttonPos = (self.size[0] - 30, self.size[1] - 30)
    #print(self.pos)

    if self.ready:

    # print(self.size)

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

Kv语言代码：

<SubWindow>:
size_hint: (None, None)
FloatLayout:
    size: root.size
    pos: root.pos
    size_hint: (None, None)
    canvas:
        Color:
            rgba: root.bColor
        Rectangle:
            size: root.size
            pos: root.pos
    Button:
        size: 20, 20
        pos: root.buttonPos
        size_hint: (None, None)
        text: "X"
        on_release: root.close(root)
    FloatLayout:
        pos: root.innerPos
        size: root.innerSize
        size_hint:(None, None)
        id: content

                pos: content.pos
                size: root.innerSize

因此，我在此末尾添加了一段代码。我做到了，所以它只将on_touch_down事件调度到子窗口的子级。

    if self.ids["content"].collide_point(*touch.pos):
        for x in self.ids["content"].walk():
            x.on_touch_down(touch)
        return True
