使用python实现下拉选择框和页签的方法

# coding=gbk
from tkinter import *
from tkinter import ttk
def showmesg(*args):
    print(color_select.get())

root=Tk()
name=StringVar()# 字符串类型变量
color_select=ttk.Combobox(root,textvariable=name)# 创建下拉选择框
color_select["values"]=("red","green","blue")# 为values属性设置三个值
color_select["state"]="readonly"# 下拉选择框 设置 只能做选择
color_select.current(0)# 显示的时候，默认选择第一个值
color_select.bind("<<ComboboxSelected>>",showmesg)
color_select.pack()
root.mainloop()

from tkinter import *

root = Tk()

variable = StringVar(root)
variable.set("Option 1") # 默认选项

option_menu = OptionMenu(root, variable, "Option 1", "Option 2", "Option 3")
option_menu.pack()

mainloop()

class Notebook(Widget):
    """Ttk Notebook widget manages a collection of windows and displays
    a single one at a time. Each child window is associated with a tab,
    which the user may select to change the currently-displayed window."""

# coding=gbk
from tkinter import *
from tkinter import ttk
root=Tk()
root.geometry("200x150")
n=ttk.Notebook(root)
f1=ttk.Frame(n,height=100,width=100)
f2=ttk.Frame(n,height=100,width=100)
n.add(f1,text="1111")
n.add(f2,text="2222")
n.pack()
root.mainloop()
