JTableHeader column selection

Here is a snippet that I am using to catch which column header is being selected.

The problem is when the user wants to resize the column width. Since Microsoft Excel allows the user to double-click between the columns to resize, if the user tries this the mouse listener is being triggered and the column is being sorted (but not resized).

Any idea on how I can determine if the mouse is being held between two columns (cursor changes to <--> instead of the default cursor)?

This seems to work okay.

        int rows = 32, cols = 4;
        String[] colIds = { "column 1", "column 2", "column 3", "column 4" };
        Object[][] data = new Object[rows][cols];
        for(int row = 0; row < rows; row++) {
            for(int col = 0; col < cols; col++) {
                data[row][col] = "item " + (row*cols+col+1);
            }
        }
        DefaultTableModel model = new DefaultTableModel(data, colIds);
        JTable table = new JTable(model);
        final JTableHeader header = table.getTableHeader();
        header.setReorderingAllowed(false);
        header.addMouseListener(new MouseAdapter() {
            public void mouseClicked(MouseEvent e) {
                int col = header.columnAtPoint(e.getPoint());

                if(header.getCursor().getType() == Cursor.E_RESIZE_CURSOR)
                    e.consume();
                else {
                    System.out.printf("sorting column %d%n", col);

        }
        SwingUtilities.updateComponentTreeUI(c);

    public static void main(String[] args) {
        HeaderLocation test = new HeaderLocation();
        JFrame f = new JFrame();
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.setJMenuBar(test.getMenuBar());
        f.getContentPane().add(new JScrollPane(test.getTable()));
        f.pack();
        f.setLocation(200,200);
        f.setVisible(true);
    }
}

perfect...I never thought about consuming the event...and I really never thought about checking for the cursor type.

thank you.
