I must say although technically incorrect there are many properties in
gambas that are Control.class but Object.class would be much more useful.

Window.Controls , Control.Proxy , etc

if it was Window.Controls As Object[]  and Control.Proxy As Object then it
would make for some much simpler programming.

But then again i guess it don't take much of a command to get over this.

Public Sub ControlObject(Ctrl As Control) As Object
  Return Ctrl
End

Print ControlObject($control.Proxy).Row
