在猕猴桃的“标签”或“按钮”中是否可以具有类似于网格的布局。
我有一个应用程序,其中包含带有产品信息的CSV文件,我想用CSV文件中的行填充MainScreen。 每行应如下所示:
最后,应按下“标签”或“按钮”以打开一个弹出窗口,以确认产品数量并进行确认。
甚至有可能还是我从错误的角度接近它?
我还没有任何代码可以用行填充MainScreen,但这是到目前为止的样子。 澄清。目前,我不需要导入CSV文件的帮助,但可以使用符合以上条件的显示方法(图片)
到目前为止,代码如下:
ATmain.py
from kivy.app import App
from kivy.uix.screenmanager import Screen, ScreenManager
from kivy.core.window import Window
from kivy.lang import Builder
from kivy.properties import StringProperty
Window.clearcolor = (1,1,1,1)
Window.size = (270, 480)
class LoginScreen(Screen):
input = StringProperty("")
class MainScreen(Screen):
username = StringProperty('')
class ScreenManagement(ScreenManager):
pass
presentation = Builder.load_file("app.kv")
class ATApp(App):
presentation = Builder.load_file("app.kv")
def build(self):
return presentation
if __name__ == '__main__':
ATApp().run()
app.kv:
# File name: main.py

on_release: root.input = input.text; app.root.current = "main"
<MainScreen>:

如果有人能指出正确的方向,我将非常感激!

奇异的破解方法是简单地使用GridLayout
或任何布局,然后给您的布局按钮属性,这样就可以单击:
from kivy.behaviors import ButtonBehavior
#then make a clickable grid
class GridButton(GridLayout, ButtonBehaviour):
def __init__(self, **kwargs):
super().__init__(**kwargs)
#Then do whatever you want to do
我猜想的另一种方法是使用on_touch_down
回调并检查触摸是否在小部件的范围内
