Way to group graphics together?

Is there a way to group graphics into one graphic? I have a rectangle with a string inside, and I want to use it for a drag and drop function, but right now it is only moving the rectangle, and the string stays put.

Also, can i make the string editable? I want the use to be able to click on it and change the text.

Any help is appreciated.

Thanks,
Shawna

import javax.swing.event.MouseInputAdapter;

public class GraphicDragAndDrop extends JPanel {
    Rectangle rect = new Rectangle(100,100,150,75);

        g2.setFont(font);
        FontRenderContext frc = g2.getFontRenderContext();
        // Some prefer to use TextLayout for this:
        float width = (float)font.getStringBounds(s, frc).getWidth();
        LineMetrics lm = font.getLineMetrics(s, frc);
        float height = lm.getAscent() + lm.getDescent();
        float x = rect.x + (rect.width - width)/2;

        g2.setPaint(Color.red);
        g2.drawString(s, x, y);
    }

    public void setRect(int x, int y) {
        rect.setLocation(x, y);
        repaint();
    }

    public static void main(String[] args) {

    Point offset = new Point();
    boolean dragging = false;

    public GraphicDragController(GraphicDragAndDrop gdad) {
        component = gdad;

        component.addMouseMotionListener(this);
    }

    public void mousePressed(MouseEvent e) {
        Point p = e.getPoint();
        Rectangle r = component.rect;
        if(r.contains(p)) {
            offset.x = p.x - r.x;
            offset.y = p.y - r.y;
            dragging = true;
        }
    }

    public void mouseReleased(MouseEvent e) {
        dragging = false;
    }

    public void mouseDragged(MouseEvent e) {

        }
    }
}

can i make the string editable? I want the use to be able to click on it and change the text
One possibility is to add a pre–configured JTextField to the panel at the location of the rect or text and have the user press the enter key to save the edit. Add an ActionListener to the textField (pre–configure) which will receive the "enter" key event. In the listener remove the editor, save the text and draw ot on the panel.
You'll have to figure out a mouse gesture to trigger the edit. Maybe a right–click. SwingUtilities has ways to detect mouse buttons.
