There's no all-in-one simple way to do it.
The best way is to set a global variable or custom property to false on
openStack, and set it to true any time the user makes any change you might
want to save. For example, if the user can type into fields, set the
variable or property on closeField. If the user can add data through menu
items, set it in the menuPick handler. And so on.
Then in the closeStackRequest handler, you can check whether the variable
or property is true or false. If it's true, ask the user to save changes.
