JTable行选择

标签: java swing jtable

当我点击JTable上的行时,我需要选择一行。默认行为是按下鼠标时,行被选中。我该如何改变这种行为?我的期望是::

鼠标按下 - >鼠标发布==>选择

鼠标按下 - >拖动鼠标 - >鼠标发布==>未选中

鼠标点击==>选择行

我想在拖动鼠标时执行其他操作,但不想更改该操作的上一行选择。

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
    }



}

我没有发现这么容易。我试图突出显示行的表不是当前活动的组件,因此您需要以下内容:

// 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();

这是“奇怪的”,但对我来说工作:

table.setDragEnabled(true);
