Jeff,
The reason you're having trouble derives from the fact that the UI (implemented
as a set of QT Widgets) doesn't know that the underlying, connected variable
has changed. You need to specifically update the UI, and tell it to repaint
itself. Thus, if you had a Float_knob named 'myKnob', and you wanted to set
its value to '12.3', you would do this:
knob("myKnob")->set_value(12.3);
knob("myKnob")->updateWidgets();
I hope that helps.
Steve

Subject: [Nuke-dev] Updating knobs
Hi everyone,
I am trying to update the value of a knob based on mouse input in the viewer.
I've used the 'handle.cpp' as a template to get myself started and am able to
change the float variable associated with a Float_Knob. But the knob itself
does not update in the nuke gui. I'm sure I'm missing some important step to
pass that value to the knob, but I can't seem to figure out what it is. Can
anybody help me out?
Cheers,
Jeff
