JButton settext specific position

I have a JButton with an image icon and I need to position the text. Is there a way to position the text of a JButton in a specific position instead of using CENTER,LEADING, TOP and so on?

Spanish: Puedes sobreescribir el método setText(String str).

Google Traductor English: You can overwrite the method setText (String str).

private static final String HTML_1 = "<html><body style='margin:0px 0px 0px 0px'>";
private static final String HTML_2 = "</html>";

@Override
public void setText(String txt) {
    if (txt.isEmpty()) {
        txt = "Dispositivo";
    }
    String txt2 = HTML_1 + txt + HTML_2;
    super.setText(txt2);
}

you can use set bounds method to set the postion of the text on the button

JLabel positiongLabel = new JLabel();
positiongLabel.setBounds(100,50,300,30);

I've never tried it on a JButton before, but maybe you can add a JLabel as a component on the button. Then you can use layout managers or Borders to position the label more appropriately.

Here are some example of adding a component to a JLabel with an Icon:

import java.awt.*;
import javax.swing.*;
import javax.swing.text.*;

public class LabelImageText extends JPanel
{
    public LabelImageText()
    {
        JLabel label1 = new JLabel( new ColorIcon(Color.ORANGE, 100, 100) );
        label1.setText( "Easy Way" );
        label1.setHorizontalTextPosition(JLabel.CENTER);
        label1.setVerticalTextPosition(JLabel.CENTER);
        add( label1 );

        //

        JLabel label2 = new JLabel( new ColorIcon(Color.YELLOW, 200, 150) );
        label2.setLayout( new BoxLayout(label2, BoxLayout.Y_AXIS) );
        add( label2 );

        JLabel text = new JLabel( "More Control" );
        text.setAlignmentX(JLabel.CENTER_ALIGNMENT);
        label2.add( Box.createVerticalGlue() );
        label2.add( text );
        label2.add( Box.createVerticalStrut(10) );

        //

        JLabel label3 = new JLabel( new ColorIcon(Color.GREEN, 200, 150) );
        label3.setLayout( new GridBagLayout() );
        add( label3 );

        JLabel text3 = new JLabel();
        text3.setText("<html><center>Text<br>over<br>Image<center></html>");
        text3.setLocation(20, 20);
        text3.setSize(text3.getPreferredSize());
        label3.add( text3 );

        //

        JLabel label4 = new JLabel( new ColorIcon(Color.CYAN, 200, 150) );
        add( label4 );

        JTextPane textPane = new JTextPane();
        textPane.setText("Add some text that will wrap at your preferred width");
        textPane.setEditable( false );
        textPane.setOpaque(false);
        SimpleAttributeSet center = new SimpleAttributeSet();
        StyleConstants.setAlignment(center, StyleConstants.ALIGN_CENTER);
        StyledDocument doc = textPane.getStyledDocument();
        doc.setParagraphAttributes(0, doc.getLength(), center, false);
        textPane.setBounds(20, 20, 75, 100);
        label4.add( textPane );
    }

    public static class ColorIcon implements Icon
    {
        private Color color;
        private int width;
        private int height;

        public ColorIcon(Color color, int width, int height)
        {
            this.color = color;
            this.width = width;
            this.height = height;
        }

        public int getIconWidth()
        {
            return width;
        }

        public int getIconHeight()
        {
            return height;
        }

        public void paintIcon(Component c, Graphics g, int x, int y)
        {
            g.setColor(color);
            g.fillRect(x, y, width, height);
        }
    }

    private static void createAndShowUI()
    {
        JFrame frame = new JFrame("LabelImageText");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.add( new LabelImageText() );
        frame.pack();
        frame.setLocationRelativeTo( null );
        frame.setVisible( true );
    }

    public static void main(String[] args)
    {
        EventQueue.invokeLater(new Runnable()
        {
            public void run()
            {
                createAndShowUI();
            }
        });
    }
}

I doubt the JTExtPane example will work with a button because the text pane will intercept the mouse events and so you will not be able to click the button when you click on the text. So I would stick with the examples that add a label to the button.
