这是为什么呢？？

Question

设置如下：可是鼠标就是不变手。YYYYYYYYYYYY((JLabel)renderComponent).setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));

Answer 1

在的呀。因为我用shubiao事件在mouseMove方法里可以显示为手。

Answer 2

static class JtableCellRender extends
            javax.swing.table.DefaultTableCellRenderer
    {
               
        /**
         * 返回单元格渲染器
         * /
 
        public Component getTableCellRendererComponent(JTable table,
                Object value, boolean isSelected, boolean hasFocus, int row,
                int column)
        {
            Component renderComponent = super.getTableCellRendererComponent(table,
                    value,
                    isSelected,
                    hasFocus,
                    row,
                    column);
            if (renderComponent instanceof JLabel)
            {
                
                ((JLabel)renderComponent).setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
                ((JLabel)renderComponent).setToolTipText(value.toString());
            }
            
            renderComponent.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
            return renderComponent;
        }
    }如上，tip提示都有效。为什么变手就没效呢。。
