防止JTable在双击时自动排序

防止JTable在双击时自动排序

我的第一种方法是使用Java接口代理替换JTable的所有现有MouseListener，拦截事件，并仅传递与单击相关的事件。

基本上就是这样工作的：

import java.awt.*;import java.awt.event.*;import javax.swing.*;import javax.swing.table.*;public class ResizeColumnListener implements MouseListener{    private static Cursor resizeCursor = Cursor.getPredefinedCursor(Cursor.E_RESIZE_CURSOR);    private MouseListener uiListener;    private JTableHeader header;    private TableColumnAdjuster tca;    public ResizeColumnListener(JTable table)    {        header = table.getTableHeader();        tca = new TableColumnAdjuster( table );        MouseListener[] listeners = header.getMouseListeners();        for (MouseListener ml: listeners)        { String className = ml.getClass().toString(); if (className.contains("BasicTableHeaderUI")) {     uiListener = ml;     header.removeMouseListener(ml);     header.addMouseListener( this ); }        }    }    @Override    public void mouseClicked( MouseEvent e )    {        if (header.getCursor() != resizeCursor)        { uiListener.mouseClicked( e ); return;        }        //  Handle the double click event to resize the column        //  Note: The last 3 pixels + 3 pixels of next column are for resizing,        //  so we need to adjust the mouse point to get the actual column.        if (e.getClickCount() == 2)        { Point p = e.getPoint(); p.x -= 3; int column = header.columnAtPoint( p ); tca.adjustColumn( column ); //  Generate event to reset the cursor header.dispatchEvent(new MouseEvent(     header,     MouseEvent.MOUSE_MOVED,     e.getWhen(),     e.getModifiers(),     e.getX(),     e.getY(),     0,     false));        }    }    @Override    public void mouseEntered( MouseEvent e )    {        uiListener.mouseEntered( e );    }    @Override    public void mouseExited( MouseEvent e )    {        uiListener.mouseExited( e );    }    @Override    public void mousePressed( MouseEvent e )    {        uiListener.mousePressed( e );    }    @Override    public void mouseReleased( MouseEvent e )    {        uiListener.mouseReleased( e );    }    public static void main(String[] args)    {        try        {//          UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());        }        catch (Exception e) { }        DefaultTableModel model = new DefaultTableModel(5, 5);        model.setValueAt("Row 0 : Column 0", 0, 0);        model.setValueAt("Row 1 : Column 1", 1, 1);        model.setValueAt("Row 2 : Column 2", 2, 2);        model.setValueAt("Row 3 : Column 3", 3, 3);        model.setValueAt("Row 4 : Column 4", 4, 4);        JTable table = new JTable( model );        table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);        table.setAutoCreateRowSorter(true);        JScrollPane scrollPane = new JScrollPane( table );        new ResizeColumnListener(table);        Jframe frame = new Jframe();        frame.setDefaultCloseOperation( Jframe.EXIT_ON_CLOSE );        frame.add( scrollPane );        frame.setSize(400, 200);        frame.setVisible(true);    }}

此代码还使用“ 表列调整器”。
