我如何从 kivy 中的“添加”按钮创建的 TextInputs 访问文本输入

Question

我想保存我在 TextInputs 中输入的文本输入，这些文本输入是由我想访问它们的添加按钮创建的，所以我可以保存在一个文件中其他一些带有 id 的方法，但它也有效，我想将它们保存在一个 txt 文件中，以便我以后可以访问它们，有什么建议吗？ 这是py文件

from datetime import date
from kivy.app import App
from kivy.factory import Factory
from kivy.uix.gridlayout import GridLayout
from kivy.properties import ObjectProperty


class MyGrid(GridLayout) :
    id_1 = ObjectProperty(None)
    id_2 = ObjectProperty(None)
    id_3 = ObjectProperty(None)
    id_4 = ObjectProperty(None)
    id_5 = ObjectProperty(None)
    id_6 = ObjectProperty(None)
    id_7 = ObjectProperty(None)
    id_10 = ObjectProperty(None)


    def perfundo (self) :
        file = open('F:\\F\\F\\' + self.id_1.text + '-' + str(date.today()) + '.txt', 'x')
        file.write('Emri dhe mbiemri :' + self.id_1.text + '\n' + 'Lloji i vetures :' + self.id_2.text + '\n' + 'Nr. i telefonit :' + self.id_3.text + '\n' + 'Problemi :' + self.id_4.text+ '\n' + 'idk :' + self.id_5.text+self.id_6.text+self.id_7.text)
        file.close()

    def add(self):
        self.ids.parts_text_inputs.add_widget(Factory.PartsTextInputs())

class HAZApp(App) :
    def build (self) :
        return MyGrid()


app = HAZApp()
app.run()

这是kv文件

Answer 1

您需要保存对它们的引用以供以后访问。例如，textinputs = ListProperty() 在班级级别，然后是t = YourTextInput(); self.textinputs.append(t); something.add_widget(t)，然后您可以通过self.textinputs 在其他地方访问该列表。
