I have a JSpinner that displays decimal values from 0.0 to 999.0. It seems to work fine, except for when it displays a number in the editor box that is four-digits long, such as 123.4; it then cuts off part of the final digit because it is not long enough.
So my question is: Does anyone know how to increase the length of the editor window of a JSpinner?
Thanks!
You can get to the text field which in fact is a JFormattedTextField
by
getEditor()
on your JSpinner to get the spinner's editorJSpinner.DefaultEditor
getTextField()
on this. Then you can set it's preferredSize if desired.Edit: as noted by trashgod though, using a proper layout is paramount and being sure that the layouts you use are the best is probably the best way to solve this issue.
Edit 2: The above is wrong as setting the textfield's preferred size does nothing. You can however set the preferred size of the editor itself, and that works. e.g .,
import java.awt.Dimension;
import javax.swing.*;
public class SpinnerBigTextField {
private static void createAndShowGui() {
JSpinner spinner = new JSpinner(new SpinnerNumberModel(0.0, 0.0, 999.0,
0.5));
JPanel panel = new JPanel();
panel.setPreferredSize(new Dimension(300, 100));
panel.add(spinner);
JComponent field = ((JSpinner.DefaultEditor) spinner.getEditor());
Dimension prefSize = field.getPreferredSize();
prefSize = new Dimension(200, prefSize.height);
field.setPreferredSize(prefSize);
JFrame frame = new JFrame("SpinnerBigTextField");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().add(panel);
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGui();
}
});
}
}
