It would look something like (note, I didn't test this):
class Example : public Iop, public ArrayKnobI::ValueProvider
{
...
void knobs(Knob_Callbacks f) {
Float_knob(f, &_a0, "a0");
Float_knob(f, &_a1, "a1");
Int_knob(f, &_which, "which");
SetValueProvider(f, this);
}
bool provideValuesEnabled(const ArrayKnobI*,
const OutputContext& oc) const
{
return true;
}
std::vector<double> provideValues(const ArrayKnobI*,
const OutputContext& oc)
{
float a0 = knob("a0")->get_value_at_view(oc.frame(), oc.view());
float a1 = knob("a1")->get_value_at_view(oc.frame(), oc.view());
std::vector<double> values;
values.push_back(a1 > a0);
return values;
}
};
