JTable have no resize cursor under a JLayeredPane

Question

Hi,
i have over my JScrollPane a JLayeredPane to show infotext.
When the JLayeredPane is over the JScrollpane you can resize the column but the JTable show no resize Cursor.
Does anybody know why?
import java.awt.Component;
import java.awt.Dimension;
import javax.swing.JComponent;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JLayeredPane;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.WindowConstants;
import javax.swing.table.DefaultTableModel;
public class NoResizeCursorDemo extends JFrame
  public NoResizeCursorDemo()
    JTable table = new JTable( new DefaultTableModel( new String[]{ "aaa", "bbb" }, 10 ) );
    JScrollPane scrollPane = new JScrollPane( table );
    InfoLayer layer = new InfoLayer( scrollPane );
    add( layer );
  public static void main( String[] args )
    NoResizeCursorDemo frame = new NoResizeCursorDemo();
    frame.setDefaultCloseOperation( WindowConstants.EXIT_ON_CLOSE );
    frame.pack();
    frame.setVisible( true );
  class InfoLayer extends JLayeredPane
    private final JComponent wrappedComponent;
    public InfoLayer( JComponent wrappedComponent )
      this.wrappedComponent = wrappedComponent;
      setLayout( null );
      add( wrappedComponent, JLayeredPane.DEFAULT_LAYER );
      setInfoText();
    private void setInfoText()
      add( new JLabel( "Info......" ), JLayeredPane.POPUP_LAYER );
      revalidate();
    @Override
    public Dimension getPreferredSize()
      return wrappedComponent.getPreferredSize();
    @Override
    public void doLayout()
      Dimension size = getSize();
      Component layers[] = getComponents();
      for ( Component layer : layers )
        layer.setBounds( 0, 0, size.width, size.height );
}Thanks

Hi,
I had almost the same problem with JTable and JSplitPane, the components worked fine, but cursor did not change when require.
I already had in place mouse events dispatching in my top layer. It passed all events to the components underneath (see example in [Glass Pane Demo Project|http://java.sun.com/docs/books/tutorial/uiswing/examples/components/GlassPaneDemoProject/src/components/GlassPaneDemo.java]; in my case the listener was the content panel of the top layer).
And now here is the trick around the cursor. Within the custom dispatch method I've called the following:
this.setCursor(comp.getCursor());
where "this" is the content panel of the layer and comp is the component where mouse event passed to.
Hope that helps!

Sergey
