删除猕猴桃中的点击图片 [英] removing Images on clicks in kivy

问题描述

我正尝试用基维制作一个基本的隐藏对象游戏，但是由于我是新手，所以有点困难.因此，我要做的是使用flowLayout画布显示了4张图像，现在我希望它们在单击 ON THEM 后消失.我应该怎么做，什么是实现这一目标的最佳方法?

I am Trying to make a basic Hidden Object Game with kivy, But since i am a novice it is a little hard. So What I have done is using the canvas of flowLayout I have displayed 4 images, now I want them to disappear once I click ON THEM. how should I do this and what is the best way to achieve this???

还有另一件事，我希望标签显示倒计时.我放置了一个标签，但是它不起作用.所以我暂时将其注释掉.如果有人可以请解释我要去哪里错了.

Also another thing, I want a label to display a countdown. I have placed a Label But It isn't working. SO I just commented out it for the time being. If some one could please explain where I am going wrong.

推荐答案

对于每个矩形，将on_press属性设置为一个函数，该函数将从其父窗口小部件中删除该矩形窗口小部件.如:

For each rectangle, set an on_press attribute to a function that removes the rectangle widget from its parent widget. Such as:

<MyWidget>:
    grid_layout: grid_layout
    AnchorLayout:
        BoxLayout:
            Image:
                source:'B_image.png'
        BoxLayout:
            Label:
                text:root.time_number
        GridLayout:
            rows: 2
            id: grid_layout
            Button:
                background_normal: 'image.png'
                on_press: root.remove_rectangle(widget=self)
            Button:
                background_normal: 'image.png'
                on_press: root.remove_rectangle(widget=self)
            Button:
                background_normal: 'image.png'
                on_press: root.remove_rectangle(widget=self)
            Button:
                background_normal: 'image.png'
                on_press: root.remove_rectangle(widget=self)

在main.py中:

class MyWidget(AnchorLayout):
    ...
    def remove_rectangle(self, widget):
        self.grid_layout.remove_widget(widget)
