I have a camera op, CroppedCamera and in the knob_changed I set the
film_width and height.
int knob_changed( Knob* k)
{
float new_aps[2];
new_aps[0] = DD_haperture * oversize.x * crop.x;
new_aps[1] = DD_vaperture * oversize.y * crop.y;
film_width(new_aps[0]);
film_height(new_aps[1])
return 1;
}
now there's also a python callback that will set some of these knobs. I'm
finding that when the values are set in the callback, the c++ knob_changed
doesn't get called again. like this:
def changed():
if nuke.thisKnob().name() == 'ddformat':
# this does NOT trigger a knob_changed!
nuke.thisNode()['oversize'].setValue([1.1, 1.1])
nuke.addKnobChanged(changed, nodeClass='CroppedCamera')
is there some flag I have to set? I haven't been able to find the
documentation for knob flags, and there are a lot of them...
thanks in advance!
Andrew
