在输入保存后重置kivy文本输入+任何其他注释

Question

我目前正在做一个程序，日志与一些不同的东西，随着工作的球拍串。我在信息保存后重置kivy文本输入时遇到问题。这段代码可能很难读懂，因为它是我在过去几天里搞乱事情的一个小拼凑。如果你能帮助我了解如何重置文本输入和任何其他改进将不胜感激-克里斯-新手

您可以在__init__()方法中保存对每个TextInput的引用，例如：

self.client = TextInput(text = "Client: ", write_tab = False, multiline=False)

然后，将Test方法移到MyGrid类中：

        def Test(self, x):
            global sheet
            list.insert(0, Client)
            list.insert(1, Racquet)
            list.insert(2, String)
            list.insert(3, Tension)
            sheet.insert_row(list, 1)
            list.clear()

            # clear the TextInput widgets here
            self.client.text = ''
            return

你的Button绑定变成：

button1.bind(on_press=self.Test)

下面是我建议的修改之后的整个MyGrid类：

class MyGrid(GridLayout):
    def __init__(self, **kwargs):
        super(MyGrid, self).__init__(**kwargs)
        self.cols = 1

        # save a reference to the client TextInput
        self.client = TextInput(text="Client: ", write_tab=False, multiline=False)
        self.client.bind(text=clients)
        self.add_widget(self.client)

        racquet = TextInput(text="Racquet: ", write_tab=False, multiline=False)
        racquet.bind(text=racquets)
        self.add_widget(racquet)

        string = TextInput(text="String: ", write_tab=False, multiline=False)
        string.bind(text=strings)
        self.add_widget(string)

        tension = TextInput(text="Tension: ", write_tab=False, multiline=False)
        tension.bind(text=tensions)
        self.add_widget(tension)

        button1 = Button(text="Submit")
        self.add_widget(button1)
        button1.bind(on_press=self.Test)   # bind to Test() method below

    def Test(self, x):
        global sheet
        list.insert(0, Client)
        list.insert(1, Racquet)
        list.insert(2, String)
        list.insert(3, Tension)
        sheet.insert_row(list, 1)
        list.clear()

        # clear the TextInput widgets here
        self.client.text = ''   # or set it to anything you want, handle the other TextInputs similarly
        return
