How to set JSpinner as non editable?

问题

I am creating time picker using a JSpinner. The text inside the JSpinner is editable. But I want to set the JSpinner as non editable, because there is the chance to give an invalid value. Can anyone help me?

回答1:

Try the following:

JSpinner spinner = ...;
((DefaultEditor) spinner.getEditor()).getTextField().setEditable(false);

This should work as long as you didn't change the spinner editor yourself by calling spinner.setEditor(...).

Tell us if this helps.

回答2:

A bit shorter:

JSpinner spinner = new JSpinner();
spinner.setEditor(new JSpinner.DefaultEditor(spinner));

回答3:

When I try this, the spinner can still be edited by click the arrow! – yelliver

You can try setting the step to 0:

mySpinner.setModel(new SpinnerNumberModel(yourDefaultDisplayValue, minValue, maxValue, step));

You can explore the other spinner models and do the same trick I guess.
