The title displayed by the button when it’s in its alternate state, as an attributed string.
- macOS 10.0+
The value of this property is the attributed string that appears on the button when it's in its alternate state, or the empty string if the button doesn’t display an alternate title. Note that some button types don’t display an alternate title. By default, a button’s alternate title is “Button.”
Graphics attributes that are set on the cell (such as
font, and so on) are overridden when corresponding properties are set for the attributed string.
