JAVA JTable Background
image
Add a background image to JTABLE. You can use this
to display your company logo or watermark. When you scroll the
table, the image also scrolls.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.table.*;
public class BackgroundImage
{
public static void main(String[] args)
{
JFrame frame = new JFrame("Background Image JTable");
frame.addWindowListener( new WindowAdapter() {
public void windowClosing(WindowEvent e)
{
Window win = e.getWindow();
win.setVisible(false);
win.dispose();
System.exit(0);
}
} );
// Create your own sub-class of JTable rather than using anonymous class
JTable table = new JTable( 15, 3 )
{
public Component prepareRenderer(TableCellRenderer renderer, int row, int column)
{
Component c = super.prepareRenderer( renderer, row, column);
// We want renderer component to be transparent so background image is visible
if( c instanceof JComponent )
((JComponent)c).setOpaque(false);
return c;
}
// Hard coded value. In your sub-class add a function for this.
ImageIcon image = new ImageIcon( "kidslovepc.gif" );
public void paint( Graphics g )
{
// First draw the background image - tiled
Dimension d = getSize();
for( int x = 0; x < d.width; x += image.getIconWidth() )
for( int y = 0; y < d.height; y += image.getIconHeight() )
g.drawImage( image.getImage(), x, y, null, null );
// Now let the regular paint code do it's work
super.paint(g);
}
};
// Set the table transparent
table.setOpaque(false);
JScrollPane sp = new JScrollPane( table );
frame.getContentPane().add( sp );
frame.pack();
frame.show();
}
