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 ;)
For this I had to write my own
int setValue(int value) {
// this->scrollvalue(value);
cout << "Called with value " << value << endl;
}
And it does get called by port_event() now
* what do I put in this setValue() in order to /actually//update/ the
widget value?
There is a int scrollvalue(int pos,int size,int first,int total); in
Fl_Slider.H but can't call it from the class, witch is not explicitely
extending Fl_Slider

from what I can see... Is it?
Thanks everybody

PS - Apparently Sorcer is using AvTK on top of FLTK, I was under the
impression that Sorcer's UI was using NTK, am I mistaking?
Eg (from OpenAV's ArtyFX, Bitta plugin)
https://github.com/harryhaaren/openAV-ArtyFX/blob/master/bitta/gui/ui.cxx#L…
How can I /get/ the control ports values from the UI perspective?
In answer to your Q, how to "get", you don't: you're told when
there's
a new value.
HTH, Cheers, -Harry
