python打开文件对话框

1.利用msgbox(单词messagebox的缩写)给出一个提示信息:

import easygui as g

reply=g.msgbox('This is a basic message box.', 'Title Goes Here')
print(reply)
#http://easygui.sourceforge.net/

运行结果:

import easygui

easygui.msgbox('Hello, world!')

运行结果:

说明:easygui.msgbox('Hello, world!')这一句有个返回值,就是字符'OK'。这个特点是:只能点击OK,返回值确定。

利用ynbox给出yes or no 对话框:
import easygui as g

reply=g.ynbox('Shall I continue?', 'Title', ('Yes', 'No'))
print(reply)
#http://easygui.sourceforge.net/

运行结果:

说明:点'Yes',返回True,点'No',返回False。

导入easygui时起个别名:
import easygui
easygui.msgbox('Hello EasyGui!')
#但是,直接使用import导入,之后使用其中的方法时需要加上easygui的前缀,例如easygui.msgbox()。这样比较麻烦,我们还可以选择导入整个EasyGui的包:
from easygui import *
msgbox('Hello EasyGui!')
#上面的方法效果时一样的。我们还有第三种方法:
import easygui as g
g.msgbox('Hello EasyGui!')
#这个方法的好处是保留了EasyGui的命名空间,且调用时不用写出完整的包名。同时避免了第二种方法导致的函数覆盖的可能

2.给出一个提示信息,并且OK按钮的内容可以更改:

from easygui import *
msgbox('您选的序号是未知序号!',ok_button = '关闭程序')

和第一个一样,返回值是字符串,只是出现的返回值的内容可以修改。


 3.打开文件对话框:

import easygui
path = easygui.fileopenbox()

 如果选择打开文件,则返回值是所打开文件的全路径,如果选择取消,则返回'None'。


4.选择多个字符串列表中的某个字符串,并返回显示在对话框上面:

import easygui as g
import sys
while True:
    g.msgbox('嗨,欢迎进入第一个GUI制作的小游戏~')
    msg = '你希望学习到什么知识呢?'
    title = '互动小游戏'
    choices = ['琴棋书画', '四书五经', '程序编写', '逆向分析']
    choice = g.choicebox(msg, title, choices)
    # note that we convert the choice to string, in case the user
    # cancelled the choice, and we got None.
    g.msgbox('你的选择是:' + str(choice), '结果')
    msg = '你希望重新开始小游戏么?'
    title = '请选择'
    if g.ccbox(msg, title):     # Show a Continue/Cancel dialog
        pass                    # user choose Continue
    else:
        sys.exit(0)             # user choose Cancel

5.和4相似的例子:

import easygui as g
import sys
while 1:
    g.msgbox("Hello, world!")

    msg ="What is your favorite flavor?"
    title = "Ice Cream Survey"
    choices = ["Vanilla", "Chocolate", "Strawberry", "Rocky Road"]
    choice = g.choicebox(msg, title, choices)

    # note that we convert choice to string, in case
    # the user cancelled the choice, and we got None.
    g.msgbox("You chose: " + str(choice), "Survey Result")

    msg = "Do you want to continue?"
    title = "Please Confirm"
    if g.ccbox(msg, title):     # show a Continue/Cancel dialog
        pass  # user chose Continue
    else:
        sys.exit(0)           # user chose Cancel

6.easygui的buttonbox:

import easygui as g

reply=g.buttonbox('Click on your favorite flavor.', 'Favorite Flavor', ('Chocolate', 'Vanilla', 'Strawberry'))
print(reply)
#http://easygui.sourceforge.net/

 7.返回选择的文件夹的名字:

import easygui as g
reply=g.diropenbox()
print(reply)

运行结果:

8.另存为对话框:

import easygui as g
reply=g.filesavebox()
print(reply)

 9.输入内容对话框:

import easygui as g
reply=g.enterbox("shuru:")
print(reply)
