How do I make a pop up in Tkinter when a button is clicked?
提问by Bob Uni
How do I make a pop-up in Tkinter when a button is clicked? When the 'About' button is clicked, I want a pop up with the disclaimer + about text.
单击按钮时如何在 Tkinter 中弹出窗口？当“关于”按钮被点击时，我想要一个带有免责声明+关于文本的弹出窗口。
I have tried to set up a def method but it must be very wrong because it's not working as I would like. Any help would be very much appreciated.
我试图建立一个 def 方法，但它一定是非常错误的，因为它没有像我希望的那样工作。任何帮助将不胜感激。
Thank you
谢谢
import sys

labelText2.set ("About \n \n \

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()

If you want to display the text on a new window, then create a Toplevel widget and use it as the parent of the labels for the about text and the disclaimer.
如果要在新窗口上显示文本，请创建一个 Toplevel 小部件并将其用作关于文本和免责声明的标签的父级。
By the way, Tkinter variables are not necessary if you have static text, so in this case you can simply get rid of them and replace them with multiline strings:
顺便说一句，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用多行字符串替换它们：
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 = """

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()
