Hello Harry;

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

Oh, I get that, believe me. The info I need is around that ; I wish your sentence had started earlier, like so "in port_event(), given this class declared like this and an objet wid instantiated like this, we do this (...)"

From my port_event() I point to my UI object via the LV2UIHandle. this object is a NTK widget (or so I hope, read on). So if I get a:

error: ‘class KisWidget’ has no member named ‘value’ (it's pretty explicit)

It means the class KisWidget has no member named "value" I guess we can agree on that ;)

It must be that I did not declare my Widget class as a proper NTK widget. The declaration is at line 25 in this file. The instantiation of the widgets (a FL_Dial and 5 FL_Slider) is at line 96 in this file.

Now for the direct questions:

Is it a proper NTK widget class declaration, that would expose a value() method?
Are those proper NTK widget class instances?

Thanks for your patience
