基于wxPython的GUI实现输入对话框（2）

Python  /  管理员 发布于 7年前   150

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:

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:

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:
