Question

我使用tkinter创建了一个供个人使用的参赛表格。现在我想添加一个函数，如果是，如果从下拉显示输入框中选择，否则隐藏它。

我已经编写了代码，但它们都没有工作抛出以下错误是我的代码片段

field = ["YES",""]
query_text = StringVar()
lblname = Label(f1aa, font=("arial", 10, "bold"), text="Query/Reply", bd=8, anchor="w")
lblname.grid(row=0, column=0, sticky=W)
txtname28 = OptionMenu(f1aa, query_text, *field)
txtname28.grid(row=0, column=1, sticky=W)

hidden = False
hidden_text = StringVar()
e = Entry(f1aa, font=("arial", 10, "bold"), bd=8, justify="left", textvariable = hidden_text)
e.grid(row=0, column=2)

if query_text == "YES":
    e.grid()
else:
    e.grid_remove()
#hidden = not hidden

root.mainloop()

我添加了完整代码

Answer 1

每次更改OptionMenu选择时，都必须确保显示或隐藏条目框的逻辑。你可以把它放在一个函数中并使用OptionMenu的command参数：

from tkinter import *

root = Tk()

def hide(choice):
    if choice == "YES":
        e.grid()
    else:
        e.grid_remove()

field = ["YES",""]
query_text = StringVar()
lblname = Label(root, font=("arial", 10, "bold"), text="Query/Reply", bd=8, anchor="w")
lblname.grid(row=0, column=0, sticky=W)
txtname28 = OptionMenu(root, query_text, *field, command=hide)
txtname28.grid(row=0, column=1, sticky=W)

hidden_text = StringVar()
hidden_text.set('Show this text?')
e = Entry(root, font=("arial", 10, "bold"), bd=8, justify="left", textvariable = hidden_text)
e.grid(row=0, column=2)

root.mainloop()

Answer 2

您要做的是将root.mainloop()替换为您自己创建的自定义循环，并将if语句合并到其中。正如你现在所拥有的那样，这个声明只会被调用一次，并且在GUI开始运行之前就已经开始了。而不是检查值是否在开始时只改变了一次，而是需要让它一直保持检查。

检查事情何时一直发生是root.mainloop()的作用，但你需要的是root.mainloop()以外的事情。所以你需要的是你自己创建的一个循环（正如我上面所说），它可以检查值何时发生变化并相应地更新GUI。

在您的循环中，您还需要确保您的GUI仍在手动响应。这通常由root.mainloop()完成，但由于您需要更换它，您需要自己完成。有很多方法可以做到这一点，但首先要查看root.update()并将其置于自己的循环中。

编辑：实际上，您是否考虑过使用复选框而不是下拉菜单？您可以攻击它的功能，并在按下它时显示或隐藏它。此外，您应该考虑启用和禁用窗口小部件，而不是隐藏或显示它。这意味着布局的问题会减少
