kivy入门之布局(六)

创建堆栈布局

from kivy.app import App
from kivy.uix.stacklayout import StackLayout


class StackLayout(StackLayout):
    """堆栈布局"""
    def __init__(self):
        super(StackLayout, self).__init__()


class Test12App(App):
    def build(self):
        self.window = StackLayout()
        return self.window


if __name__ == '__main__':
    Test12App().run()

kv语言：

<StackLayout>:
    orientation: 'lr-tb' # 布局的方向,从左到右,从上到下
    padding: [20, 10]
    spacing: [20, 10]
    Button:
        text: 'a'
        size_hint: [.2, .1]
    Button:
        text: 'a2'
        size_hint: [.2, .1]
    Button:
        text: 'a3'
        size_hint: [.2, .1]
    Button:
        text: 'a4'
        size_hint: [.2, .1]
    Button:
        text: 'a5'
        size_hint: [.2, .1]
    Button:
        text: 'a6'
        size_hint: [.2, .1]
