is it possible to turn off the highlighting 'feature' when I draw a LineObject inside my ObjectData plugin's Draw() function? Currently if my object is selected the lines are drawn white.

Hi WickedP, thanks for writing us.
With reference to your request, could you please better explain your final intent? Could you also confirm that you need to draw a line using the BaseDraw::DrawLine() in ObjectData::Draw() rather than dealing with LineObject which has completely different purposes?

I'm wanting to draw a spline in an ObjectData's Draw() function. So I'm getting the LineObject from a SplineObject, and using DrawObject() to draw the LineObject. Psuedo code:
// set spline points
LineObject *line = Spline->GetLineObject(nullptr,0.0,nullptr)
The spline/line is drawn fine. But it's highlighted - I want the colour drawn to the colour I set regardless of whether the object is selected or not.

Hi WickedP, thankls for following up.
To avoid having your item "highlighted" simply draw it in the DRAWPASS_OBJECT rather than in the DRAWPASS_HIGHLIGHTS being sure that the pen color is set to BaseDraw::GetObjectColor() instead of BaseDraw::GetHighlightPassColor().

that's the thing, I'm drawing it in DRAWPASS_OBJECT and setting the pen colour isn't having any effect. It just draws the line white unless I deselect my object. This is a stripped down version of my function (psuedo to keep it minimal) :
DRAWRESULT My_Object::Draw(BaseObject *op,DRAWPASS drawpass,BaseDraw *bd,BaseDrawHelp *bh)
if(drawpass == DRAWPASS_OBJECT)
// set spline points/tangents here
// (spline is a class level variable)
LineObject *line = My_Spline->GetLineObject(nullptr,0.0,nullptr);
// this line doesn't change anything
Vector col = Vector(1.0,0.0,0.0);
Draw_Result = bd->DrawObject(bh,line,DRAWOBJECT_EDITMODE|DRAWOBJECT_FORCEPOINTS|DRAWOBJECT_USE_CUSTOM_COLOR,drawpass,nullptr,col);
if(Draw_Result == DRAWRESULT_OK)
Just in addition to the highlighting issue, the DRAWOBJECT_FORCEPOINTS flag doesn't seem to do anything here. Can I draw points from the line object as well?
Edit: fixed typo.

I know this is a couple of months old, but I'm having a really frustrating time with this. I've tried returning the spline in GVO instead but it does the same thing. When I add a cube and set the colour with ObjectColorProperties the cube is coloured fine. Why are splines different?
Can I colour the spline so that it's not affected by the draw highlight? There must be a way. How is the normal spline object drawn (with the white-to-blue curve colour and points)?
