The class name for a ttk::spinbox is TSpinbox.

Dynamic states: active, disabled, focus, readonly.

TSpinbox styling options configurable with ttk::style are:

-arrowcolor color
-arrowsize amount

For backwards compatibility, when using the aqua theme (for macOS), this option behaves as an alias for the -fieldbackground provided that no value is specified for -fieldbackground. Otherwise it is ignored.

-bordercolor color

-darkcolor color
-fieldbackground color
-foreground color
-insertcolor color
-insertwidth amount
-lightcolor color
-padding padding
-selectbackground color

Some options are only available for specific themes.
