备忘以记录！

--------------

1.设置行颜色

private Map rowIndex_map = new HashMap();

    

    DefaultTableCellRenderer dtc = new DefaultTableCellRenderer(){  

        public Component getTableCellRendererComponent(JTable table,  

                Object value, boolean isSelected, boolean hasFocus,  

                int row, int column) {

        System.out.println(row);

        if(rowIndex_map.containsKey(row)){

        this.setBackground(Color.red);

        }

        else{

        this.setBackground(Color.white);

        }

         return super.getTableCellRendererComponent(table, value,  

                 isSelected, hasFocus, row, column); 

         

        }  

    };  

rowIndex_map.put(1, 1);

        rowIndex_map.put(2, 2);

        table.getColumnModel().getColumn(0).setCellRenderer(dtc);

2.默认打开桌面路径

JFileChooser fileChooser = new JFileChooser();
FileSystemView fsv = FileSystemView.getFileSystemView();  //注意了，这里重要的一句
System.out.println(fsv.getHomeDirectory());                //得到桌面路径
fileChooser.setCurrentDirectory(fsv.getHomeDirectory());
