How to make scroll the JLabel in java?

[ramjeev]

Hi,

I m trying to scroll the JLabel by adding JLabel to Jscrollpane,I can see the scrollbar,but I can't scroll as well as I found JLabel's are misplaced.Can anyone please help me to solve this.

The following is the code,

class outerWindow extends JFrame  implements  KeyListener,ActionListener
{
	Container c = null;
	JPanel pane;

	public outerWindow()
	{

		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		c = getContentPane();
		pane = new JPanel(null);
		pane.setLayout(null);
		pane.setBounds(0,0,750,550);
		pane.setBackground(Color.gray);


	JLabel lab_test = new JLabel("Test");
	lab_test.setBounds(0,10,210,1000);
	lab_test.setBackground(Color.yellow);
	lab_test.setForeground(Color.black);
	lab_test.setOpaque(true);
	lab_test.setFont(new java.awt.Font("Arial",1,30));
	lab_test.setHorizontalAlignment(JTextField.CENTER);		
	lab_test.setFocusable(false);
	lab_test.setVisible(true);

	JLabel[] lab = new JLabel[50];

	for(int i=0;i<50;i++)
	{
		lab[i] = new JLabel("new");		
		lab[i].setBounds(70*(i%3),70*(i/3),70,70);
		lab[i].setOpaque(true);
		lab[i].setBackground(Color.green);		
		lab[i].setFont(new java.awt.Font("Arial",1,30));
		lab[i].setVerticalAlignment(JTextField.BOTTOM);
				
		JLabel labIn = new JLabel("Boost");
		labIn.setBounds(0,0,65,20);
		lab[i].add(labIn);

		lab_test.add(lab[i]);
	}


JScrollPane scrPane = new JScrollPane(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS, 
JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
scrPane.setBounds(50,10,230,300);
//scrPane .getViewport().add( lab_test);
scrPane.add( lab_test);
pane.add( scrPane , BorderLayout.CENTER ); 

		c.add(pane);
		c.setBackground(Color.white);
		c.addKeyListener(this);

		setSize(800,600);
		this.setVisible(true);
		c.requestFocus();
	}

--Thanks--

You probably need to add the labels to a jpanel then add that panel to the scroll pane.

Thanks buddy,

Its cleared in some way now.I m using JscrollBar seperately and JPanel seperately fix both closely so that its seems that its own scroll.I m loaded n number of labels in that panel.When I scroll, i m refreshing the labels with new text,so that its seems to be scroll.
