当单击按钮时，如何在Tkinter中制作弹出窗口？

Question

当单击“关于”按钮时，我想要一个弹出窗口显示免责声明和关于文本。我该如何在Tkinter中制作弹出窗口？我尝试使用def方法来设置它，但它似乎有很多错误，没有按照我想要的方式工作。非常感谢任何帮助。

谢谢。

import sys
from Tkinter import *

def clickAbout(): 
    name = ("Thanks for the click")
    return

app = Tk()
app.title("SPIES")
app.geometry("500x300+200+200")

labelText = StringVar()
labelText.set ("Please browse to the directory you wish to scan")


labelText2 = StringVar()
labelText2.set ("About \n \n \
SPIES will search your chosen directory for photographs containing \n \
GPS information. SPIES will then plot the co-ordinates on Google \n \
maps so you can see where each photograph was taken.")

labelText3 = StringVar()
labelText3.set ("\n Disclaimer \n \n \
Simon's Portable iPhone Exif-extraction Software (SPIES) \n \
software was made by Simon. This software \n \
comes with no guarantee. Use at your own risk")

label1 = Label(app, textvariable=labelText, height=0, width=100)
label1.pack()

label1 = Label(app, textvariable=labelText2, height=0, width=100)
label1.pack()

label = Label(app, textvariable=labelText3, height=0, width=100)
label.pack()

b = Button(app, text="Quit", width=20, command=app.destroy)
b.pack(side='bottom',padx=0,pady=0)

button1 = Button(app, text="About SPIES", width=20, command=clickAbout)
button1.pack(side='bottom',padx=5,pady=5)

app.mainloop()

如果您想在新窗口中显示文本，则创建一个Toplevel小部件，并将其用作关于文本和免责声明标签的父级。

顺便提一下，如果您有静态文本，则不需要Tkinter变量，因此在这种情况下，您可以简单地摆脱它们并将它们替换为多行字符串：

import sys
from Tkinter import *

ABOUT_TEXT = """About

SPIES will search your chosen directory for photographs containing
GPS information. SPIES will then plot the co-ordinates on Google
maps so you can see where each photograph was taken."""

DISCLAIMER = """
Disclaimer

comes with no guarantee. Use at your own risk"""

def clickAbout():
    toplevel = Toplevel()
    label1 = Label(toplevel, text=ABOUT_TEXT, height=0, width=100)
    label1.pack()
    label2 = Label(toplevel, text=DISCLAIMER, height=0, width=100)
    label2.pack()


app = Tk()
app.title("SPIES")
app.geometry("500x300+200+200")

label = Label(app, text="Please browse to the directory you wish to scan", height=0, width=100)
b = Button(app, text="Quit", width=20, command=app.destroy)
button1 = Button(app, text="About SPIES", width=20, command=clickAbout)
label.pack()
b.pack(side='bottom',padx=0,pady=0)
button1.pack(side='bottom',padx=5,pady=5)

app.mainloop()

谢谢，那真是帮了大忙了。 - Bob Uni

@Bob：你可能需要在clickAbout()函数的末尾添加toplevel.focus_force()来激活新窗口（这是大多数应用程序中的工作方式）。 - martineau

这对我也非常有帮助。但是 import sys 不是必需的。 - WinEunuuchs2Unix
