Selecting the currently selected item in a spinner

问题

I have a spinner widget that only has one item by default, "Create new..."

My problem is if there is only one item in the spinner list, it's already selected, so clicking on it again doesn't trigger anything.

Is there any way to detect when an item is re-selected?

Thanks.
