WORK AROUND The following workaround is meant for 1.4.2 only. It adds rollover handling for the table headers and also corrects the header size problem described in bug 4774013. import java.awt.*; import java.awt.event.*; import javax.swing.*; import javax.swing.border.*; import javax.swing.table.*; import com.sun.java.swing.plaf.windows.*; public class XPTableHeaderRenderer extends DefaultTableCellRenderer implements MouseListener, MouseMotionListener { private JTableHeader header; private DefaultTableCellRenderer oldRenderer; private int rolloverColumn = -1; public XPTableHeaderRenderer(JTableHeader header) { this.header = header; this.oldRenderer = (DefaultTableCellRenderer)header.getDefaultRenderer(); header.addMouseListener(this); header.addMouseMotionListener(this); } private void updateRolloverColumn(MouseEvent e) { int col = header.columnAtPoint(e.getPoint()); if (col != rolloverColumn) { rolloverColumn = col; header.repaint(); } } public void mouseMoved(MouseEvent e) { updateRolloverColumn(e); } public void mouseEntered(MouseEvent e) { updateRolloverColumn(e); } public void mouseExited(MouseEvent e) { rolloverColumn = -1; header.repaint(); } public void mousePressed(MouseEvent e) { rolloverColumn = -1; header.repaint(); } public void mouseReleased(MouseEvent e) { updateRolloverColumn(e); } public void mouseClicked(MouseEvent e) { } public void mouseDragged(MouseEvent e) { } public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { JComponent comp = (JComponent)oldRenderer.getTableCellRendererComponent(table, value, isSelected, hasFocus || (column == rolloverColumn), row, column); comp.setBorder(new EmptyBorder(3, 8, 4, 8)); return comp; } public static void main(String[] a) throws Exception { UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); JFrame f = new JFrame(); JTable table = new JTable(5, 5); f.getContentPane().add(new JScrollPane(table)); if (System.getProperty("java.version").startsWith("1.4.2")) { // Replace the XP renderer with our own final JTableHeader header = table.getTableHeader(); TableCellRenderer renderer = header.getDefaultRenderer(); String name = renderer.getClass().getName(); if (name.equals("com.sun.java.swing.plaf.windows.WindowsTableHeaderUI$XPDefaultRenderer")) { header.setDefaultRenderer(new XPTableHeaderRenderer(header)); } } f.setBounds(100, 100, 200, 200); f.setVisible(true); } } ###@###.### 2003-08-29
