Hi Bill,
beginEdit() and endEdit() are VST functions called before and after a
control has been moved in a custom editor
derived from Steinberg's "AEffEditor".
In my case, I'm using a custom GUI (drawing straight into a carbon
window) and the Emagic VSTAU wrapper.
The product I'm working on is designed to be as cross-platform as
possible (there's a PC VST version) - with the help of our own graphics
library.
I appreciate it's probably not the 'pure' way AU's were designed to
work but the cross-platform approach really has paid dividends for
the development of this product.
If I'm doing something dangerous or devious then I'm open to
suggestions !! :-)
Cheers,
Ben.
