接着上一篇基于wxpython的gui输入对话框1，继续学习。
在程序输入中，有时会要求同时改变多个参数值,而且类型也不尽相同,
这时textentrydialog就显得不适用了.wxinput模块则比较彻底的解决了这个问题.
比如我有三个值要用户交互式设置,一个是int数,一个是str,一个是float,先看示例文件:
|
1
2
3
4
5
|
from winput import inputboxvalues={'int':1,'string':'this is string','float':3.5}title='setting values:'rvalues=inputbox(title,values)print(rvalues) |
显示gui如下:
上面的代码的关键是设置字典values的值.
wxinput会自动根据字典values的内容生成输入界面,
而且返回值的类型确保和原始类型一样.
再比如程序中有任意两个参数method和num要设置,那么如下就可了:
|
1
2
3
|
title='setting values:'values={'method':'loglog','value':3.5}rvalues=inputbox(title,values) |
生成的界面如下:
wxinput模块的代码如下:
