See, I know the value of each control port this way:

static void port_event(LV2UI_Handle ui,
               uint32_t port_index,
               uint32_t buffer_size,
               uint32_t format,
               const void * buffer)
{
    KisGUI *self = (KisGUI *) ui;

    if (port_index == 3)
      cout << "Volume is " << (*static_cast<const float*>(buffer)) << "  Format is " << format << endl;

    cout << "Port event on index " << port_index << "  Format is " << format << endl;

    return;
}

It's call at session opening, so that would already solve the problem at that time.
But how can I access the UI widget to pass it the value?

The problem is to find documentation on NTK... All plugin sources that I can find use Qt or GTK...
But either way, I need to uderstad te logic of it : How does the UI read values?

But when I turn the controls in the hosts generic UI, nothing moves in the UI.

Also each time the UI is opened, the widgets are reset at maximum (not the values).

How can I get the control ports values from the UI perspective?
