The valid range for this application is 0 to 9 but there seems to be no NetBeans 7.0.1 JSpinner minimum or maximum value setting. Is there another way to limit the range of this JSpinner to 0..9?

Step 1:
Step 2:

That works for me.
回答2:
// from 0 to 9, in 1.0 steps start value 5
SpinnerNumberModel model1 = new SpinnerNumberModel(5.0, 0.0, 9.0, 1.0);
JSpinner spin1 = new JSpinner(model1);
回答3:
You'll have to use this constructor of SpinnerNumberModel
.
Snippet:
JFrame frame = new JFrame("Limiting value for a JSpinner");
SpinnerModel sm = new SpinnerNumberModel(0, 0, 9, 1); //default value,lower bound,upper bound,increment by
JSpinner spinner = new JSpinner(sm);

yes but without bothering insert code and/or with generated code from GUI Palette
add SpinnerListModel (easiest for this requirement and example in Oracle tutorial) or wrote own SpinnerNumberModel
