Specifies one of three states for the default ring:
- normal
- active
- disabled
In active state, the button is drawn with the platform specific appearance for a default button.
In normal state, the button is drawn with the platform specific appearance for a non-default button, leaving enough space to draw the default button appearance. The normal and active states will result in buttons of the same size.
In disabled state, the button is drawn with the non-default button appearance without leaving space for the default appearance. The disabled state may result in a smaller button than the active state.
