JComboBox

[Ian Lockwood]

I am using a JComboBox populated with a Vector. I want the text to be inset from the left edge of the box, at the moment it is tight to the left hand edge for a JTextField I have used Insets
class FormJTextField extends JTextField
{
FormJTextField()
{
setFont( new Font( "Dialog", Font.BOLD, 16 ));
setMargin(new Insets(4, 4, 4, 4));
}
FormJTextField(String tipTxt)
{
setFont( new Font( "Dialog", Font.BOLD, 16 ));
setMargin(new Insets(4, 4, 4, 4));
setToolTipText(tipTxt);
}
}
how do I do this for a JComboBox?

Hi,
Try with this
combobox.setHorizondalalighnment(jlabel.right);

thanx & regards,

Thanks for that but the JComboBox does not have a setHorizontalAlignment method.
The combobox is made up of three components a comboboxbutton a CellRendererPane and a JTextField,
I have tried setting the margins for the JTextField and although this setting is set when I do println of the combobox it does not look any different.
More help please
:roll:

I think this does what you want it to do...

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
 
public class FormatCombo extends JFrame {
 
    private JComboBox combo;
 
    public static void main( String[] arg ) {
        new FormatCombo();
    }
 
    public FormatCombo() {
        JPanel p = new JPanel();
        combo = new JComboBox();
        combo.setFont( new Font( "Dialog", Font.BOLD, 16 ) );
        JComponent c = (JComponent)combo.getRenderer();
        c.setBorder( BorderFactory.createEmptyBorder( 4, 14, 4, 4 ) );
        combo.setRenderer( (ListCellRenderer)c );
        for ( int i = 0; i < 10; i++ ) {
            combo.addItem( "item " + ( i + 1 ) );
        }
        p.add( combo );
        getContentPane().add( p );
        addWindowListener( new WindowAdapter() {
            public void windowClosing( WindowEvent e ) {
                System.exit( 0 );
            }
        } );
        setSize( 300, 300 );
        setVisible( true );
    }
}
