tkinter的entry的值为什么显示不了？

Question

各位帮帮忙吧，为什么显示不了项目名称？

from tkinter import *   #导入tkinter库
from tkinter import messagebox as ms
import time as t    #导入time库

def new_prog():     #定义‘新建项目’函数
    global dstr
    window2 = Toplevel()
    window2.geometry('210x100+320+100')
    window2.attributes("-topmost", True)    #位于最上层
    window2.resizable(height=False, width=False)    #大小不可调
    window2.title('选项')     #设置标题

    dstr = StringVar()
    
    Label(window2, text='项目名称', width=6).place(x=18, y=5)
    Entry(window2, width=10, textvariable=dstr).place(x=5, y=25)
    
    def click_yes():
        window2.destroy()
        label1 = Label(window, text=dstr, width=8,font=('kaiti', 18, 'bold'))
        label1.place(x=100, y=90)
        #window.update()
    def click_no():     #定义‘取消’按钮函数
        window2.destroy()

    Label(window2, text='小时', width=6).place(x=100, y=5)
    Spinbox(window2, from_=0, to=23, width=5, wrap=True).place(x=100, y=25)

    Label(window2, text='分钟', width=6).place(x=150, y=5)
    Spinbox(window2, from_=0, to=59, width=5, wrap=True).place(x=150, y=25)

    Button(window2, text='确定', width=6, command=click_yes).place(x=50, y=70)

    Button(window2, text='取消', width=6, command=click_no).place(x=110, y=70)
    
    window2.mainloop
    return

def config():
    def clickyes():
        window3.destroy()

    def clickno():
        window3.destroy()

    def a1():
        window.attributes("-alpha", 0.2)

    def a5():
        window.attributes("-alpha", 0.8)

    def a6():
        window.attributes("-alpha", 1)

    window3 = Tk()
    window3.geometry('310x200+320+50')
    window3.title('设置')
    window3.attributes("-topmost", True)
    window3.resizable(height=False, width=False)

    Label(window3, text='透明度(%)', width=10).place(x=5, y=5)

    Radiobutton(window3, text='20%', value=0, command=a1).place(x=0, y=30)
    Radiobutton(window3, text='40%', value=1, command=a2).place(x=50, y=30)
    Radiobutton(window3, text='50%', value=2, command=a3).place(x=100, y=30)
    Radiobutton(window3, text='60%', value=3, command=a4).place(x=150, y=30)
    Radiobutton(window3, text='80%', value=4, command=a5).place(x=200, y=30)
    Radiobutton(window3, text='100%', value=5, command=a6).place(x=250, y=30)

    Button(window3, text='确定', width=8, command=clickyes).place(x=80, y=170)
    Button(window3, text='取消', width=8, command=clickno).place(x=155, y=170)

    window3.mainloop


window = Tk()
window.geometry('300x300+0+0')
window.title('时间管理器')
window.attributes("-alpha", 1)
window.attributes("-topmost", True)
window.resizable(height=False, width=False)

Button(window, text='新建项目', width=10, command=new_prog).place(x=0, y=50)
Button(window, text='设置', width=10, command=config).place(x=220, y=50)
Label(window,text='当前任务:',width=8,font=('kaiti', 16, 'bold')).place(x=0,y=90)

label2=Label(window,text=t.strftime('%H:%M:%S',t.localtime(t.time())),font=('huawenxihei', 28, 'bold'))
label2.pack(anchor=N)
def trickit():
    currentTime=t.strftime('%H:%M:%S',t.localtime(t.time()))
    label2.config(text=currentTime)
    window.update()
    label2.after(1000, trickit)
label2.after(1000, trickit)
    
window.mainloop()

第20行代码label1 = Label(window, text=dstr, width=8,font=('kaiti', 18, 'bold'))中的text=dstr应该改为text=dstr.get()
