Question

我希望用户单击按钮后输入一个值。我试图在单击按钮的函数中定义条目，但是什么也没出现？单击按钮时，标签会发生变化，具体情况与我在功能中对其配置的含义相同，但没有出现该条目。

def jan():
    Birth_Month = "January"
    January.forget()
    February.forget()
    March.forget()
    April.forget()
    May.forget()
    June.forget()
    July.forget()
    August.forget()
    September.forget()
    October.forget()
    November.forget()
    December.forget()
    Title.configure(text="So you were born in January")
    Month.configure(text="What date in January?")
    Date = tkinter.Entry(window)
    Birth_Date = Date.get()
    Birth_Date = Birth_Date.int()

Answer 1

要显示小部件，需要在对象上使用几何管理器之一（pack，grid，place）。

Date = tkinter.Entry(window)
Date.pack() # or grid, place depending on rest of your code

此外，为了不每次都创建 new Entry，您应该在函数的全局范围外创建Entry，并在函数内部pack中创建

Date = tkinter.Entry(window) # somewhere in your code that is accessible to your method

def jan():
    Date.pack()

（Tkinter）单击按钮后如何显示输入按钮？
