如何将图像和时钟添加到 kv 文件

Question

我正在尝试实现 ComicCreator GUI sample as a template for my own project. The code is easy to follow, but I want to change the toolbox.kv 的模板，使其看起来像：

问：我怎样才能附加一个徽标，而不是当前那里的按钮，并且还可以显示当前日期时间（DD/MM/YYYY HH:MM) showed perpetually.And 最后添加一个字符串 NYC, New York, USA，如图所示。

如果您的图片来自网络，有些人会使用 BoxLayout 和 Image 或 AsyncImage。

因此 python 代码可能如下所示。

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.properties import StringProperty
from kivy.clock import Clock
import time


class MyLayout(BoxLayout):
    your_time = StringProperty()
    def __init__(self,**kwargs):
        super(MyLayout,self).__init__(**kwargs)
        self.orientation = "vertical"
        self.padding = 10
        Clock.schedule_interval(self.set_time, 0.1)    

    def set_time(self,dt):
        self.your_time = time.strftime("%m/%d/%Y %H:%M")

class MyApp(App):
    def build(self):
        return MyLayout()


if __name__ == "__main__":
    MyApp().run()

kv 文件看起来像这样。

#:kivy 1.9.1

<MyLayout>:
    BoxLayout:
        spacing: 10
        padding: 10,10,10,0
        orientation: "horizontal"
        BoxLayout:
            orientation: "vertical"
            size_hint: 0.3,1
            canvas:
                Rectangle:
                    pos: self.pos
                    size: self.size
            AsyncImage
                source: 'http://lmsotfy.com/so.png'
            Label:

                text: root.your_time
                color: [0,0,0,1]
            Label:
                size_hint: 1,0.3
                text: "NYC, New York, USA"
                color: [0,0,0,1]

        Button:
            text: ""

    BoxLayout:
        padding: 10,10,10,0
        spacing: 10
        size_hint: 1,0.3
        orientation: "horizontal"
        Button:
            text: "Clear"
        Button:
            text: "Remove"
        Button:
            text: "Group"
        Button:
            text: "Color"
        Button:
            text: "Gestures"

    BoxLayout:
        padding: 10,10,10,10
        size_hint: 1,0.3
        Button:
            text: "Total figures: 1          Kivy Started"
