这是我现在制作的程序,但我有问题......当我点击按钮1然后打开新窗口时我该怎么做
import sys
from tkinter import *
import tkinter as tk
def mhello1():
mlabel = Label(mGui, text='A1').pack()
def mhello2():
mlabel = Label(mGui, text='A2').pack()
def mhello3():
mlabel = Label(mGui, text='A3').pack()
def mhello4():
mlabel
return
def mAbout():
messagebox.showinfo(title="About",message="program")
return
def mQuit():
mExit = messagebox.askyesno(title="Quit",message="y/n")
if mExit > 0:
mGui.destroy()
return
mGui = Tk()
mGui.geometry('450x450+200+200')
mGui.title('program')
mGui.configure(bg='gray')
mlabel = Label(text='option:',fg='red',bg = 'blue').pack()
mbutton1 = Button(mGui,text ='Button1',command = mhello1, height=5, width=20).pack()
mbutton2 = Button(mGui,text ='Button2',command = mhello2, height=5, width=20).pack()
mbutton3 = Button(mGui,text ='Button3',command = mhello3, height=5, width=20).pack()
mbutton4 = Button(mGui,text ='Button4',command = mhello4, height=5, width=20).pack()
mlabel2 = Label(text='activity:',fg='red',bg = 'blue').pack()
menubar=Menu(mGui)
filemenu = Menu(menubar, tearoff = 0)
filemenu.add_command(label="qwer")
filemenu.add_command(label="quit",command = mQuit)
menubar.add_cascade(label="more options",menu=filemenu)
helpmenu = Menu(menubar, tearoff = 0)
helpmenu.add_command(label="Help Docs")
helpmenu.add_command(label="About", command = mAbout)
menubar.add_cascade(label="help",menu=helpmenu)
mGui.config(menu=menubar)
mGui.mainloop()
我尝试了这个程序,但它不起作用: Python 3 and tkinter opens new window by click the button
有没有办法不使用 tkinter 顶层?
Tnx 很多 :)
