Python EasyGUI - 索引框

索引框：用于在 EasyGUI 中显示具有多个选项的窗口，即按钮，可用于需要获取用户选择的选项的地方。它类似于按钮框，但用于按钮具有相同名称的地方，它根据它的索引指定选定的按钮。按钮的索引从 0 开始，下面是索引框的样子

In order to do this we will use indexbox method

Syntax : indexbox(message, title, buttons)

Argument : It takes 3 arguments, first string i.e message/information to be displayed, second string i.e title of the window and third is list of strings i.e buttons

Return : It returns return of the index selected by the user

例子 ：
在此我们将创建一个带有添加按钮的索引框，当按下任何按钮时，它将根据索引在屏幕上显示特定的消息，下面是实现

# importing easygui module
from easygui import *
  
# message / information to be displayed on the screen
message = "Select any one button"
  
# title of the window
title = "GfG - EasyGUI"
  
# list of buttons 
buttons = ["First", "Second", "Third", "Fourth"]
  
# creating a index box
output = indexbox(message, title, buttons)
  
  
# showing new message according to the buttons pressed
# if index is 0
if output == 0:
      
    # message / information
    message = "First"
# if index is 1
elif output == 1:
      
    # message / information
    message = "Second"
      
# if index is 2
elif output == 2:
      
    # message / information
    message = "Third"
      
# if index is 3
elif output == 3:
      
    # message / information
    message = "Fourth"
  
      
# message 
message = message + " Button Pressed"
# title of the window
title = "GfG - EasyGUI"
   
# creating a message box
msg = msgbox(message, title)
     

输出 ：

另一个例子 ：
在此我们将创建一个不设置任何按钮的索引框，当按下任何按钮时，它将根据索引在屏幕上显示特定的消息，下面是实现

# importing easygui module
from easygui import *
  
# message / information to be displayed on the screen
message = "Select any one button"
  
# title of the window
title = "GfG - EasyGUI"
  
# creating a index box
output = indexbox(message, title)
  
  
# showing new message according to the buttons pressed
# if index is 0
if output == 0:
      
    # message / information
    message = "First"
# if index is 1
elif output == 1:
      
    # message / information
    message = "Second"
      
  
# message 
message = message + " Button Pressed"
  
# title of the window
title = "GfG - EasyGUI"
   
# creating a message box
msg = msgbox(message, title)
     

输出 ：
