在 Python Tkinter 中保留输入字段 [英] Retain entry field in Python Tkinter

问题描述

我的 GUI 中有一个弹出文本输入字段，要求输入两个条目 #1 文件路径 #2 项目(这些引用了 Excel 表)

I have a pop up text entry field as part of my GUI asking for two entries #1 Filepath #2 Item (these reference an excel sheet)

文件路径很少更改，但仍需要在需要时更改它的能力

The filepath will rarely change but the ability to change it when needed is still required

是否可以在输入字段中保留文件路径，这样就不需要每次都输入?即关闭并重新打开输入字段后仍包含 C:\*\*\*\*\*\somthing.xlsx.

Is it possible to retain the filepath in the entry field so it dosnt require typing each and every time? i.e after closing and re opening the entry field still contains C:\*\*\*\*\*\somthing.xlsx.

master = Tk()
master.title("Entry Field")
Label(master, text="Filepath: ").grid(row=0)
Label(master, text="Item Number: ").grid(row=1)
e1 = Entry(master)
e2 = Entry(master)
e1.grid(row=0, column=1)
e2.grid(row=1, column=1)

def entry_field():
    print("Filepath: %s" % (e1.get()))
    print("Item No: %s" % (e2.get()))

    Button(master, 
           text = 'Accept', 
           command = entry_field).grid(row=3, column=1, sticky=W, pady=4)

    root.mainloop()

推荐答案

tk.Entry 小部件将保留这些值，直到您将它们重置为新值(您可以在按 Accept 时看到这一点)按钮多次而不修改 Entry；因此您不需要做任何特殊的事情.

The tk.Entry widget will keep the values until you reset them to a new value (you can see this when pressing the Accept button several times without modifying the Entry; you therefore do not need to do anything special.

您可以主动在条目中插入默认值:

You could pro-actively insert a default value in your entry:

import tkinter as tk

def entry_field():
    print("Filepath: %s" % (e1.get()))
    print("Item No: %s" % (e2.get()))

master = tk.Tk()
master.title("Entry Field")
tk.Label(master, text="Filepath: ").grid(row=0)
tk.Label(master, text="Item Number: ").grid(row=1)


e1 = tk.Entry(master)
e2 = tk.Entry(master)
e1.insert(0, 'C:*****\somthing.xlsx')    # <-- this string will be inserted in the Entry by default

e1.grid(row=0, column=1)
e2.grid(row=1, column=1)

tk.Button(master, text = 'Accept', command = entry_field).grid(row=3, column=1,
                                sticky=tk.W, pady=4)
master.mainloop()

这是该条目现在默认显示的方式:

This is how the entry appears by default now:
