Re: [Audacity-devel] Re: Choice control for Nyquist plugins

Cool!

Arun, I've been thinking it would be great to use the same little  
comment strings we use in Nyquist as a general way to build effect  
dialog GUIs.  Not all effects, of course - but quite a few of them  
could be handled that way.  It would dramatically reduce the amount  
of code in effects classes.  What do you think?

I'm not sure if it would be best to stick with strings, or possibly  
just build up a nice object-oriented infrastructure that can handle  
adding a standard audio effect control (text box + slider, or  
checkbox, or choice) with a single line of code.
