提问by Arivu2020
I am creating time picker using a JSpinner. The text inside the JSpinneris editable. But I want to set the JSpinneras non editable, because there is the chance to give an invalid value. Can anyone help me?

Try the following:
请尝试以下操作：
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(...).
只要您没有通过调用spinner.setEditor(...).
Tell us if this helps.
告诉我们这是否有帮助。

A bit shorter:
短一点：
JSpinner spinner = new JSpinner();
spinner.setEditor(new JSpinner.DefaultEditor(spinner));

When I try this, the spinner can still be edited by click the arrow! – yelliver
当我尝试此操作时，仍然可以通过单击箭头来编辑微调器！– 耶利弗
You can try setting the step to 0:
您可以尝试将步长设置为 0：
mySpinner.setModel(new SpinnerNumberModel(yourDefaultDisplayValue,
minValue, maxValue, step));
mySpinner.setModel(new SpinnerNumberModel(yourDefaultDisplayValue,
minValue, maxValue, step));
You can explore the other spinner models and do the same trick I guess.
您可以探索其他微调模型并执行我猜的相同技巧。
