When I turn the controls in my UI, the controls move in the hosts
generic UI ;
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?

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?

Hi Phil,
Glad to see you're excited and working hard on learning LV2! Checkout the
example plugins: they show how things work.
In the UI, there is a port_event() function. It tells the UI what port
changed, and what its current value is. Use this to do widget->setValue(
newValue ); and you're done ;)
Eg (from OpenAV's ArtyFX, Bitta plugin)
https://github.com/harryhaaren/openAV-ArtyFX/blob/master/bitta/gui/ui.cxx#L…

In answer to your Q, how to "get", you don't: you're told when
there's a
new value.
HTH, Cheers, -Harry

In
this very example, value() seems to be a method of graph object, but
when I look at it :
{ graph = new Avtk::Crusher(5, 36, 150, 126, "graph");
graph->box(FL_UP_BOX);
graph->color((Fl_Color)179);
graph->selection_color(FL_INACTIVE_COLOR);
graph->labeltype(FL_NO_LABEL);
graph->labelfont(0);
graph->labelsize(14);
graph->labelcolor(FL_FOREGROUND_COLOR);
graph->callback((Fl_Callback*)cb_graph);
graph->align(Fl_Align(FL_ALIGN_BOTTOM));
graph->when(FL_WHEN_CHANGED);
} // Avtk::Crusher* graph
Still can't see the setValue() you are talking about... I do see
when(FL_WHEN_CHANGED); used a lot in your plugins, is when() what I'm
looking for?
Thanks -Phil
