in the simple snippet
var go = new Rhino.Input.Custom.GetObject(); go.SetCommandPrompt("Select the input boundary curve you want to use for controlling the tween curves."); go.GeometryAttributeFilter = Rhino.Input.Custom.GeometryAttributeFilter.ClosedCurve; var type = new OptionInteger(2, 1, 3); int oi = go.AddOptionInteger("Control type", ref type, "Select the shape of control you want to add: Gaussian(1)," + "Rectangle (2), " + "Triangle (3), ");
oi ends up being zero, in other words the method AddOptionInteger of the GetObject returns unsucessfully. I seemed unable to figure out the reason for its failing.
And, if I may add a second question: what is the typical use case for a GetOption object, if options can be added directly to a GetObject without constructing a GetOption? Is this just for the rare case when a command does not need to reference a document object? (it doesn’t help the intuition that both classes are typically instanced with an object called “go”, and have a few similiar/overlapping method names.)
