JTable行選擇

Question

當我點擊JTable上的行時，需要選擇一行。默認行爲是按下鼠標時，該行被選中。我怎樣才能改變這種行爲？我的期望是::

鼠標按下 - >鼠標發佈==>選擇

鼠標按下 - >鼠標拖拽 - >鼠標發佈==>未選擇

鼠標單擊==>選中行

我想在拖動鼠標時執行其他操作，但不想更改該操作的上一行選擇。

public class JTableDemo extends MouseAdapter { 
int selection; 


    public static void main(String[] args) throws Exception 
    { 
     JFrame frame = new JFrame(); 
     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
     String[] headers = {"A", "B", "C"}; 
     Object[][] data = {{1, 2, 3}, {4, 5, 6}}; 
     JTable table = new JTable(data, headers); 
     JScrollPane scroll = new JScrollPane(); 
     scroll.setViewportView(table); 
     frame.add(scroll); 
     frame.pack(); 
     frame.setVisible(true); 
     table.addMouseListener(new JTableDemo()); 
     scroll.addMouseListener(new JTableDemo()); 
    } 

    @Override 
    public void mousePressed(MouseEvent e) 
    { 
     JTable jtable = (JTable) e.getSource(); 
     selection= jtable.getSelectedRow(); 
     jtable.clearSelection(); 
    } 
    @Override 
    public void mouseReleased(MouseEvent e){ 
     JTable jtable = (JTable) e.getSource(); 
     //now you need to select the row here check below link 
    } 



}

我認爲這沒有那麼容易。我試圖以突出行的表是不是當前活動的組成部分，所以你需要的東西，如：

// get the selection model 
ListSelectionModel tableSelectionModel = table.getSelectionModel(); 

// set a selection interval (in this case the first row) 
tableSelectionModel.setSelectionInterval(0, 0); 

// update the selection model 
table.setSelectionModel(tableSelectionModel); 

// repaint the table 
table.repaint();

這是「STANGE」，但爲我工作：

table.setDragEnabled(true);
