What GUI library are you using here, AWT or Swing? What are you drawing your graphics in, a JComponent or JPanel? Have you tried simply placing a graphics JPanel into a JScrollPane? If so, has it not worked?

[hardwired]

class Pseudo extends JPanel {
    protected void paintComponent(Graphics g) {
        // drawing code...
    }

    public Dimension getPreferredSize() {
        // The parent scrollPane will ask for this
        // and use it to set its scrollbars to
        // make this component fully visible.
        return new Dimension(desired width and height);
    }
}

Pseudo drawingPanel = new Pseudo();
JScrollPane scrollPane = new JScrollPane(pseudo);
JFrame f = new JFrame();
...
f.add(scrollPane);
f.setSize(any size you like); // scrollPane does the rest
