I am trying to use the Window plugin to add a CheckBox to a popup menu at a specific index. The help and wiki state:
addCheckBox([name], [method], [icon], [mnemonic], [enabled], [align])
Add the Checkbox at the selected index (starting at 0) or add it at the end (empty).
I think I am missing something simple but I can't see where you specify the index in the addCheckBox method?
