public static void setDefaultProperties(SpinnerItem spinnerItemProperties)
Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

are both null
or unspecified, the nextValueHandler is used to get the next higher value from the
currentValue. The default implementation returns (currentValue + step).
To indicate that the given currentValue is the maximum value, return currentValue again.
Implementations should expect to be passed any value for currentValue. Also, if
step
is non-negative,
the nextValueHandler must induce a monotonically increasing (non-decreasing) function;
otherwise, the nextValueHandler must induce a monotonically decreasing function.
public void setPreviousValueHandler(PreviousValueHandler handler)
min

are both null
or unspecified, the previousValueHandler is used to get the previous lower value from the

To indicate that the given currentValue is the minimum value, return currentValue again.
