JSpinner & unlimited max value

M

Mike Mimic

Hi!

Why this does not work:

new JSpinner(new SpinnerNumberModel(1, 1, null, 1));

I get this compiler error:

cannot resolve symbol
symbol: constructor SpinnerNumberModel (int,int,<nulltype>,int)

But in the documentation it is written:

The minimum and maximum properties can be null to indicate that the
sequence has no lower or upper limit.

You're using the wrong constructor (and you cant use null when a primitive
type, in this case int, is expected).

Take a closer look at the api docs for the correct constructor:
http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/SpinnerNumberModel.html

Look closely. You need the constructor that takes Numbers and Comparable
instances, not the constructor that takes ints, which is the one you are
calling.

Example:
new SpinnerNumberModel(new Integer(50), new Integer(1), null, new
Integer(1));

Either the primitive int you pass for minimum (try Integer)
or you need to cast null.

Try

new JSpinner(
new SpinnerNumberModel(1, new Integer(1), (Comparable)null, 1)
);

Thanks to all of you. Now it works.
