基于wxpython的GUI输入对话框2
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:
[python]
from WInput import InputBox
values={'int':1,'String':'This is String','float':3.5}
title='Setting values:'
rvalues=InputBox(title,values)
print(rvalues)
from WInput import InputBox
values={'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:
[html]
title='Setting values:'
values={'Method':'LogLog','Value':3.5}
rvalues=InputBox(title,values)
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:
