How do I change the color of the pink box and blue arrow here?
I have tried this code:
diagram.toolManager.dragSelectingTool.box =
$make(go.Part, { layerName: 'Tool', selectable: false },
$make(go.Shape, { name: 'SHAPE', fill: null, stroke: 'red', strokeWidth: 2 })
);
But it has not worked. Thanks for any help you can provide!
