JSpinner size problem

Thread view:

Steven T Abell - 08 Sep 2004 20:15 GMT

I made a JSpinner with the height of a JTextField with the default font.
The spin buttons don't size down correctly,
ending up in the layout about twice the height of the textfield.
I've applied various forms of arm-twisting without results.
Is this a known bug, or is there a trick, or am I just doing it wrong?

Try posting compileable code, that is
both more productive, *and* less painful..

There's always the possibility that someone already knows the problem,
but here it is:

import javax.swing.*;
import javax.swing.border.*;

public static void main(String[] avs)
{
JSpinner oSpinner = new JSpinner();
oSpinner.setBorder(new TitledBorder("Spinner"));
JPanel oPanel = new JPanel();
oPanel.setLayout(new BorderLayout());
oPanel.add(oSpinner,BorderLayout.NORTH);
JFrame oFrame = new JFrame();
oFrame.setContentPane(oPanel);
oFrame.show();
}

Very true (and noted in the document), but
it does help get people's interest and help..

Well.. no. Did you actually try compiling that?
I *went* to do so, but the moment came when I
went to save it as it's class name and..

After making a few 'tweaks I came up with this
(that actually does compile).

<sscce>
import java.awt.BorderLayout;
import javax.swing.*;
import javax.swing.border.*;

public class SpinnerHeightTest {

public static void main(String[] avs)
{
JSpinner oSpinner = new JSpinner();
oSpinner.setBorder(new TitledBorder("Spinner"));
JPanel oPanel = new JPanel();
oPanel.setLayout(new BorderLayout());
oPanel.add(oSpinner,BorderLayout.NORTH);
JFrame oFrame = new JFrame();
oFrame.setContentPane(oPanel);

// oFrame.show(); //deprecated in 1.5
oFrame.setVisible(true);
// always a good idea
oFrame.pack();
}
}
</sscce>

Before the call to pack() the UI was only
the title bar, after, I did not observe the
behaviour you described. Using WinXp and
Java 1.5.0 beta, the JSpinner seemed the size
I would expect of a JTextField.

(shrugs) Back to you.

I copied it out of the file in which I wrote it.
Within the class defined there, it does compile and run.

I'm using XP and 1.4.2.
I dug deeper into the bug database, found something similar.
In 1.4.2, JSpinner's sizing machinery doesn't account for borders.
I've treated the problem by embedding the spinner in a panel,
then putting the border on the panel.

How could we possibly know? Personally, my crystal ball is somewhat dirty
and it isn't letting me see the code you didn't post.
