如何在Tkinter中的列表中创建下拉菜单？ [英] How can I create a dropdown menu from a List in Tkinter?

问题描述

我正在创建一个用于构建有关一个人的信息的GUI。我希望用户使用一个下拉栏选择他们的出生月份，并将之前的月份配置为列表格式。

I am creating a GUI that builds information about a person. I want the user to select their birth month using a drop down bar, with the months configured earlier as a list format.

from tkinter import *

birth_month = [
    'Jan',
    'Feb',
    'March',
    'April'
    ]   #etc


def click():
    entered_text = entry.get()

Data = Tk()
Data.title('Data') #Title

label = Label(Data, text='Birth month select:')
label.grid(row=2, column=0, sticky=W) #Select title

如何创建一个下拉列表来显示月份？

How can I create a drop down list to display the months?

推荐答案

要创建一个下拉列表下拉菜单，则可以在tkinter中使用 OptionMenu

To create a "drop down menu" you can use OptionMenu in tkinter

OptionMenu基本示例：

from Tkinter import *

master = Tk()

variable = StringVar(master)
variable.set("one") # default value

w = OptionMenu(master, variable, "one", "two", "three")
w.pack()

mainloop()

从列表中创建月份的 OptionMenu 很简单：

Creating an OptionMenu of the months from a list would be as simple as:

from tkinter import *

OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc

master = Tk()

variable = StringVar(master)
variable.set(OPTIONS[0]) # default value

w = OptionMenu(master, variable, *OPTIONS)
w.pack()

mainloop()

要检索用户选择的值，您可以简单地使用 .get（）分配给小部件的变量，在以下情况下，这是变量：

In order to retrieve the value the user has selected you can simply use a .get() on the variable that we assigned to the widget, in the below case this is variable:

from tkinter import *

OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc

master = Tk()

variable = StringVar(master)
variable.set(OPTIONS[0]) # default value

w = OptionMenu(master, variable, *OPTIONS)
w.pack()

def ok():
    print ("value is:" + variable.get())

button = Button(master, text="OK", command=ok)
button.pack()

mainloop()
