我是靠谱客的博主漂亮魔镜，最近开发中收集的这篇文章主要介绍Python -- Gui编程 -- Tkinter的使用 -- 对话框消息框，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

1.消息框

tkMessageBox.py

 1 import tkinter
 2 from tkinter import messagebox
 3
 4 def cmd():
 5
global n
 6
global buttontext
 7
n += 1
 8
if n==1:
 9
messagebox.askokcancel('Python Tkinter', 'askokcancel')
10
buttontext.set('askquestion')
11
elif n==2:
12
messagebox.askquestion('Python Tkinter', 'askquestion')
13
buttontext.set('askyesno')
14
elif n==3:
15
messagebox.askyesno('Python Tkinter', 'askyesno')
16
buttontext.set('showerror')
17
elif n==4:
18
messagebox.showerror('Python Tkinter', 'showerror')
19
buttontext.set('showinfo')
20
elif n==5:
21
messagebox.showinfo('Python Tkinter', 'showinfo')
22
buttontext.set('showwarning')
23
else:
24
n = 0
25
messagebox.showwarning('Python Tkinter', 'showwarning')
26
buttontext.set('askokcancel')
27
28 n = 0
29 root = tkinter.Tk()
30 buttontext = tkinter.StringVar()
31 buttontext.set('askokcancel')
32 button = tkinter.Button(root, textvariable=buttontext, command=cmd)
33 button.pack()
34 root.mainloop()

2.简单对话框

tkSimpleDialog.py

 1 import tkinter
 2 from tkinter import simpledialog
 3
 4 def inputStr():
 5
r = simpledialog.askstring('Python Tkinter', 'Input String', initialvalue = 'Python Tkinter')
 6
print(r)
 7 def inputInt():
 8
r = simpledialog.askinteger('Python Tkinter', 'Input Integer')
 9
print(r)
10 def inputFloat():
11
r = simpledialog.askfloat('Python Tkinter', 'Input Float')
12
print(r)
13
14 root = tkinter.Tk()
15 btn1 = tkinter.Button(root, text='Input String', command=inputStr)
16 btn2 = tkinter.Button(root, text='Input Integer', command=inputInt)
17 btn3 = tkinter.Button(root, text='Input Float', command=inputFloat)
18
19 btn1.pack(side='left')
20 btn2.pack(side='left')
21 btn3.pack(side='left')
22
23 root.mainloop()

3.文件对话框

tkFileDialog.py

 1 import tkinter
 2 from tkinter import filedialog
 3
 4 def openfile():
 5
r = filedialog.askopenfilename(title='打开文件', filetypes=[('Python', '*.py *.pyw'), ('All Files', '*')])
 6
print(r)
 7 def savefile():
 8
r = filedialog.asksaveasfilename(title='保存文件', initialdir='d:mywork', initialfile='hello.py')
 9
print(r)
10
11 root = tkinter.Tk()
12 btn1 = tkinter.Button(root, text='File Open', command=openfile)
13 btn2 = tkinter.Button(root, text='File Save', command=savefile)
14
15 btn1.pack(side='left')
16 btn2.pack(side='left')
17 root.mainloop()
