今天做了个基于pyqt4和pyside的输入对话框.已放到pypi中,包名wlab，大家可以使用pip安装：
pip install wlab
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,
这时下面的模块比较彻底的解决了这个问题.先看个示例吧.
比如我们有三个参数,分别为int,float,和字符串类型:
|
1
2
3
4
5
|
values={'string':'this is string','float':3.5,'int':15}groupboxtitle='please set values:'title='qinputbox:'rvalues=qinputbox(values=values,groupboxtitle=groupboxtitle,title=title)print(rvalues) |
生成的gui界面如下:
返回的结果中我们注意到字典rvalues里面数据的类型和字典valuse中时一致的.
也就是说:
如果values中是整数,那么rvalue中的值也是整数;
如果value中是浮点数,那么rvalue中的值也是浮点数;
如果value中是字符串,那么rvalue中的值也是字符串;
目前只支持这三种类型.但对values中输入参数并没有没有数目限制.
对于不会使用pip的新手，可以复制下面的文件：
