JSpinner没有显示

Question

I really doesn't understand what it's going on with my JSpinner. I instanciated it and then I tried to set it on my JPanel with a setBounds but the only thing I get is this :

The little square on the middle is what should be my JSpinner..

My code is like this :

private JSpinner spinnerDayBirth;
spinnerDayBirth = new JSpinner();
spinnerDayBirth.setBounds(280,351, 25, 25);
add(spinnerDayBirth);

They're few lines betweens each of these instructions but they never touch to this JSpinner.

So I wonder why I can't get a normal JSpinner.. Thank you in advance !

I had same problem. I worked with simply spinnerModel then I tried your program and it works too. There is one thing to do - re-set your model. If you want the spinner to appear you have to set new spinner model again.

for example i typed this code:

    public void method() {
       jPanel2.setLocation(0, 96);
       jPanel2.setSize(getWidth(), getHeight() - 96);
       jPanel2.getHeight() - jButton1.getHeight() - 50);
       jSpinner1.setModel(new SpinnerNumberModel(2,1,10,1));   //<- this is line you need to type
       jSpinner1.setSize(60, 25);
       jSpinner1.setLocation(0,0);
}
