scroll a Jpanel in a JFrame

[nidhirastogi]

Hi All
I need to make a JPanel inside a JFrame Scrollable. I have implemented a hexagonal grid in the Jframe and need to scroll it horizontally n vertically.
Plz. help.

My JPanel Code is :

public class DisplayPanel extends JPanel
{
private static final long serialVersionUID = 1L;
private int xMax=1000, yMax=1000;
// public Point2D listAP;

// DistancefromMN distMN = new DistancefromMN();
JLabel label;

class MyAdjustmentListener implements AdjustmentListener
{
public void adjustmentValueChanged(AdjustmentEvent e) {
repaint();
}
}

public DisplayPanel(int xMax,int yMax)
{
super(true);
this.xMax=xMax;
this.yMax=yMax;
setLayout(new BorderLayout());
setLayout(new BorderLayout());

JScrollBar hbar = new JScrollBar(
JScrollBar.HORIZONTAL, 30, 20, 0, 300);
JScrollBar vbar = new JScrollBar(
JScrollBar.VERTICAL, 30, 40, 0, 300);

hbar.setUnitIncrement(2);
hbar.setBlockIncrement(1);

hbar.addAdjustmentListener(new MyAdjustmentListener());
vbar.addAdjustmentListener(new MyAdjustmentListener());

add(hbar, BorderLayout.SOUTH);
add(vbar, BorderLayout.EAST);

}
}


and JFrame:

public class DisplayFrame extends JFrame
{
private static final long serialVersionUID = 1L;
private int maxX,maxY;

public DisplayFrame()
{
setLayout(new BorderLayout());
setTitle("Wireless Environment");
setSize(1290, 1290);
setDefaultCloseOperation(EXIT_ON_CLOSE);
Toolkit toolkit = getToolkit();
// JScrollBar hbar = new JScrollBar(JScrollBar.HORIZONTAL, 30, 20, 0, 300);
// JScrollBar vbar = new JScrollBar(JScrollBar.VERTICAL, 30, 40, 0, 300);
// vbar.addAdjustmentListener(new MyAdjustmentListener());
// add(hbar, BorderLayout.SOUTH);
// add(vbar, BorderLayout.EAST);
DisplayPanel p=new DisplayPanel(maxX,maxY);
this.getContentPane().add(p);
this.validate();
setVisible(true);

}
class MyAdjustmentListener implements AdjustmentListener
{
public void adjustmentValueChanged(AdjustmentEvent e) {
//label.setText(" New Value is " + e.getValue() + " ");
repaint();
}
}
public static void main(String args[])
{
new DisplayFrame();

}
}

I think that you posted this in the wrong forum, that you wanted to post this in the Swing forum. Oh well, it's close anyway. Question though: why not just use a JScrollPane? That should make this whole thing easy.
