About using addoptionlist in getobject class!

I want to use addoptionlist in getobject class. But It seems useless. see the code below. can you tell me where am I wrong. Thank you in advance!

 Protected Overrides Function RunCommand(ByVal doc As RhinoDoc, ByVal mode As Rhino.Commands.RunMode) As Rhino.Commands.Result
            Const geometryFilter As ObjectType = ObjectType.Brep
            Dim rc As Rhino.Commands.Result = Rhino.Commands.Result.Failure

            'Dim cutmode1 As New OptionToggle(True, "否", "是")
            'Dim cutmode2 As New OptionToggle(False, "否", "是")
            go.SetCommandPrompt("请选取被当前平面切割的物件(Select  Objects to cut)")
            go.GeometryFilter = geometryFilter
            go.AddOptionToggle("是否保留原物件", opbl)
            Dim listIndex As Integer = 1
            Dim opList As Integer = go.AddOptionList("保留侧(Side to reserve)", New String() {"两侧(Both side)", "Z轴正侧(Z aixs side)", "Z轴负侧(-Z aixs side"}, listIndex)
            'go.AddOptionToggle("保留Z轴正向物件", cutmode1)
            'go.AddOptionToggle("保两侧切割物件", cutmode2)

            go.GroupSelect = True

Have you had a chance to review this sample?

Yes,I have saw it many times. but I don’t know where my code has problem. getmultiple can’t use addoptionlist??

This seems to work here - what a I missing?

      Dim go As New Rhino.Input.Custom.GetObject()
      go.SetCommandPrompt("Select objects")

      Dim listValues As String() = New String() {"Item0", "Item1", "Item2", "Item3", "Item4"}
      Dim listIndex As Integer = 3
      Dim opList As Integer = go.AddOptionList("List", listValues, listIndex)

      While (True)
        Dim res As Rhino.Input.GetResult = go.GetMultiple(1, 0)
        If (go.CommandResult() <> Rhino.Commands.Result.Success) Then
          Return go.CommandResult()
        End If

        If (res = Rhino.Input.GetResult.Object) Then
          Rhino.RhinoApp.WriteLine("List = {0}", listValues(listIndex))
        ElseIf (res = Rhino.Input.GetResult.Option) Then
          If go.OptionIndex() = opList Then
            listIndex = go.Option().CurrentListOptionIndex
          End If
          Continue While
        End If

        Exit While
      End While

Yes,you have missed special char. It seems I can’t use special character like “-”, space,"()" and so on in listvalues’ element and go.addoptionlist’s english name param.! very weird. try my code,you will find it.

What you say is true - the strings in your list cannot contain special characters, as many of them have other meaning in the context of parsing the command line.

It’s terrible about the help documentation of rhinocommon SDK. I find it’s too hard to write a rhp or gha for developer.HOpe you can’t give some more detail documentation. See the help about cad.net,They have done a good job. I hope you can make a documentation like that. Thank you!

Hi,

is there a way in updating the lets say second option list based on the first option list. If you want to give the option of a List of Lists, how do you do that?

Any help would be great.

Thanks
