Re: Re[4]: [paragui-users] script language for Paragui

[atani]

Perhaps its even easier than this...

We can perhaps create an xml definition of the widgets and require the 
user to create this definition file to ensure "proper" code insight, 
etc of their custom widgets... And if they do not have a definition 
file we can resort to parsing the file...

How does this sound?
