Using Custom Messages in a Get operation

gistfile1.cs

// Your "get" class will have code that looks like.
var go = new Rhino.Input.Custom.GetOption();
var optDbl = new Rhino.Input.Custom.OptionDouble(12, 0,100);
go.SetCommandPrompt("Give me an option");
go.SetCommandPromptDefault("");
go.AcceptCustomMessage(true);  // NEW!!
while (true)
{
  // need to clear and reset the command options every iteration because
  // Rhino doesn't know that it needs to update the option string
  go.ClearCommandOptions();
  go.AddOptionDouble("x", ref optDbl);
  var result = go.Get();
  if( result== Rhino.Input.GetResult.Option)
    continue;
  if( result==Rhino.Input.GetResult.CustomMessage)
  {
    // NEW - custom message was sent from somewhere
    object msg = go.CustomMessage();
    if (msg != null)
    {
      if (msg is int)
        optDbl.CurrentValue = (int)msg;
      else if (msg is double)
        optDbl.CurrentValue = (double)msg;
    }
    continue;
  }
  break;
}

// Somewhere else in code...
// Probably your button click event handler

{
  // NEW - send a custom message from anywhere and your Get()
  // will retrieve it as a custom message
