I think that this code snippet helps you.
import javax.swing.*; import java.awt.*; /** * ...Scrolldescription... * * @author ...yourname... * @version 1.00, 2006/04/23 */ public class Scroll extends JFrame { // properties Container c; JScrollPane scrolls; // constructors public Scroll(){ scrolls = new JScrollPane(new imagePanel(), ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS, ScrollPaneConstants.HORIZONTAL_SCROLLBAR_ALWAYS ); scrolls.setPreferredSize(new Dimension(600,600)); c = getContentPane(); c.add(scrolls); setVisible(true); pack(); setExtendedState(JFrame.MAXIMIZED_BOTH); } // methods public static void main( String[] args) { new Scroll(); } } // end of class Scroll class imagePanel extends JPanel{ ImageIcon imageIcon; Image image; JButton but; public imagePanel(){ setPreferredSize(new Dimension(800,800)); imageIcon = new ImageIcon("snake.gif"); image = imageIcon.getImage().getScaledInstance(128, 128, Image.SCALE_FAST); but = new JButton("mert"); add(but); } protected void paintComponent(Graphics g){ g.drawImage(image, 0, 0, getWidth(), getHeight(), this); } }

Make your panel, which is added into your ScrollPane, have bigger size than ScrollPane's size, so that you scrollBars can appear.

I think it does not matter whether you draw your picture on Frame or Panel but you should be careful that while drawing on Frame use paint(Graphics g) method and while drawing on Panel use paintComponent(Graphics g)method.

Sorry, I mean that the only familiar one is JPanel

The others;

AbstractButton, BasicInternalFrameTitlePane, Box, Box.Filler, JColorChooser, JComboBox, JFileChooser, JInternalFrame, JInternalFrame.JDesktopIcon, JLabel, JLayeredPane, JList, JMenuBar, JOptionPane, JPanel, JPopupMenu, JProgressBar, JRootPane, JScrollBar, JScrollPane, JSeparator, JSlider, JSpinner, JSplitPane, JTabbedPane, JTable, JTableHeader, JTextComponent, JToolBar, JToolTip, JTree, JViewport

Sorry I said that JDialog has paintComponent(Graphics g) method but it does not have.
Only, JPanel has paintComponent(Graphics g) method

Close, although really not the best solution. You shouldn't override paint(), but rather paintComponent(); and when you do, you should call super.paintComponent() first. Overriding paint() in a Swing component just makes a mess of things.

I think he is correct by suggesting paint method for drawing.
Because, I know that paintComponent(Graphics g) should be used for Java Swing components, not containers. If you draw something on JPanel or JDialog, use paintComponent(Graphics g), otherwise use paint(Graphics g).

Oh, sorry for forgetting the tell the class that the above method belongs to.
It is kept in Graphics class.

Try to use the following method to cear all the Frame screen:
clearRect(int x, int y, int width, int height)

followingExamine this

Write setVisible(true) after adding all the components(or containers) into your Top Level Container(JFrame).

If your file is directory, so can you guess what happened ??

Oh, thanks very much for this extremely explanatory reply.
Now, I think that I kept the idea.

Again thanks very much for this.

Yes, it increases the efficiency by having readLine method...

Sorry but it is a little bit messy for me.
Would you mind being more clear ?
