java重新定位Jtable列标题

Question

我必须禁用右键单击JTableHeader，这样用户就不能右键单击列标题并拖动来重新定位列。我们有什么办法吗？只需提一下，鼠标左键点击效果很好，但当用户点击并拖动列时，该列将被移动，并在释放鼠标时在其他列上重新绘制

任何帮助都将不胜感激

在我看来，用右键触发列拖动/调整大小显然是一个错误

一个古怪的解决方法是挂接uidelegate安装的鼠标/运动/侦听器，并静默地吃掉所有不是左键的事件。类似于（注意：这个包装侦听器的一个更健壮的安装是outlined in a recent answer，它可以在LAF切换后继续使用）：

public static class BugHook implements MouseListener, MouseMotionListener {

    private JTableHeader header;
    private MouseListener mouseDelegate;
    private MouseMotionListener motionDelegate;

    public BugHook(JTableHeader header) {
        this.header = header;
        MouseListener[] ls = header.getMouseListeners();
        for (int i = 0; i < ls.length; i++) {
            header.removeMouseListener(ls[i]);
            String name = ls[i].getClass().getName();
            if (name.contains("TableHeaderUI")) {
                this.mouseDelegate = ls[i];
                ls[i] = this;
            }
        }
        for (MouseListener l : ls) {
            header.addMouseListener(l);
        }

        MouseMotionListener[] motionLs = header.getMouseMotionListeners();
        for (int i = 0; i < motionLs.length; i++) {
            header.removeMouseMotionListener(motionLs[i]);
            String name = motionLs[i].getClass().getName();
            if (name.contains("TableHeaderUI")) {
                this.motionDelegate = motionLs[i];
                motionLs[i] = this;
            }
        }
        for (MouseMotionListener l : motionLs) {
            header.addMouseMotionListener(l);
        }

    }

    // methods delegation left buttons only
    @Override
    public void mousePressed(MouseEvent e) {
        if (!SwingUtilities.isLeftMouseButton(e)) return;
        mouseDelegate.mousePressed(e);
    }

    @Override
    public void mouseDragged(MouseEvent e) {
        if (!SwingUtilities.isLeftMouseButton(e)) return;
        motionDelegate.mouseDragged(e);
    }
    @Override
    public void mouseReleased(MouseEvent e) {
        if (!SwingUtilities.isLeftMouseButton(e)) return;
        mouseDelegate.mouseReleased(e);
    }

    ///       methods delegating always
    @Override
    public void mouseClicked(MouseEvent e) {
        mouseDelegate.mouseClicked(e);
    }
    @Override
    public void mouseEntered(MouseEvent e) {
        mouseDelegate.mouseEntered(e);
    }

    @Override
    public void mouseExited(MouseEvent e) {
        mouseDelegate.mouseExited(e);
    }
    @Override
    public void mouseMoved(MouseEvent e) {
        motionDelegate.mouseMoved(e);
    }

}
