基维蟒蛇| 位置文本输入

Question

我想将我的 TextInput（即字段）放在 的左侧，但我不能这样做：

Answer 1

我建议在 kv scrpit 中重新排列您的 gui。

代替

Label:
    ...
TextInput:
    ...

和

BoxLayout:
    orientation:'horizontal'
    Label:
        ...
    TextInput:
        ...
    

Answer 2

用代码示例和帮助链接回答第二个问题（ https://www.geeksforgeeks.org/python-textinput-in-kivy-using-kv-file/ ）

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.button import Button
from kivy.uix.textinput import TextInput
from kivy.uix.label import Label


class MyApp(App):
    def build(self):
        title = "Sample Layout not using kv file"
        layout = BoxLayout(orientation='horizontal')
        self.textinput = TextInput(text="")
        self.textinput.bind(text=self.get_text)
        self.btn1 = Button(text='Move text to label')
        self.btn1.bind(on_press=self.get_text)
        self.btn2 = Button(text='World')
        self.lbl1 = Label(text="text goes here")
        layout.add_widget(self.textinput)
        layout.add_widget(self.btn1)
        layout.add_widget(self.btn2)
        layout.add_widget(self.lbl1)
        return layout  

    def get_text(self, *args):
        print(self.textinput.text)
        self.lbl1.text = "You wrote " + self.textinput.text


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