Hi Philippe,

I can't follow the issue you're having here: you've sent 8 emails, most with different questions with a layout that is hard to follow: please be more careful in what text you reply to, and remove all the rest of the email. Then make sure you're repling to the "linux-audio-dev" list, and not (only) to the individual.

If you're struggling with code, take a step back, and write a single email, with a direct question, that sums up what you're trying to learn.

Eg:

How does setValue() work to updated a widgets value in NTK, in the context of an LV2 plugin?

To which I would answer:

Most NTK widgets that have a "value" like a slider or a dial, derive from a base class that implements value() and value( float );

What this means for a widget, is that in order to change the value of a widget called "wid", we do this:

wid->value( 0.0f ); // sets widget value to 0

What you will see here: https://github.com/harryhaaren/openAV-ArtyFX/blob/master/ui/crusher.h#L156

Is the value() call, which returns the value stored in the base class, aka 0.0f in this case.

To connect an LV2 port to a widget, in port_event() have this type of code:

Which checks the port number, and assigns the incoming value to the widget, using the value( float ); call.

Its pretty simple right? Cool.

RE: the other emails, Yes Sorcer uses NTK, NTK is in turn based on FLTK, and to maintain backwards compatibility with existing code, the function names weren't changed.
