How to modify highlights for GoBasicNodes

GoDiagram (6 and previous)
1

The default highlight for a GoBasicNode (a thin rectangle around
the node’s bounding box) isn’t visible enough for my application.
However, I can’t find where that rectangle’s stroke width or color
are specified. Does anyone know?

(I’m not 100% sure I’m actually getting default behavior, but
I started with the FlowCharter example, and I also don’t
see in it where the details of the highlight rectangles are
specified.)
Thanks,
Mark Shirley

Try setting some or all of the following GoView properties: BoundingHandlePenWidth, PrimarySelectionColor, SecondarySelectionColor, NoFocusSelectionColor.
For resizable objects, instead of BoundingHandlePenWidth, there are: ResizeHandlePenWidth, ResizeHandleHeight, ResizeHandleWidth.
