This has a range of [code]-2^32[/code] to [code]2^32 - 1[/code], i.e. [code]-2147483648[/code] to [code]2147483647[/code].

Text [Color] used when the [OptionButton] is being pressed. The horizontal space between the arrow icon and the right edge of the button. The horizontal space between [OptionButton]'s icon and text.
