java - 如何设置鼠标监听器使其无法在另一个表中单击？

Question

我有一张带有播放列表的表。当我双击播放列表时，我会看到该播放列表的电影。

但是，当我双击电影时，我会得到一个空 table 。因此，我不想单击电影表。如何防止这种行为？

这是我的听众:

playlistTable.addMouseListener(new MouseAdapter() {
    public void mouseClicked(MouseEvent e) {
        if (e.getClickCount() == 2) {

            JTable target = (JTable)e.getSource();
            int row = target.getSelectedRow();

            videoTableModel = new VideoTableModel(playlistService.getMoviesOfPlaylist(row));
            target.setModel(videoTableModel);

            movieTable.setEnabled(true);

            createPlaylist.setEnabled(false);
            setButtonIcon("icons\\playlist_grau.png", createPlaylist, "createPlaylist");

            removePlaylist.setEnabled(false);
            setButtonIcon("icons\\bin_grau.png", removePlaylist, "removePlaylist");

            playlistTable.setEnabled(false);

            revalidate();

        }
    }
});

感谢您的回答。

要么从表中删除鼠标监听器，要么设置一个标志以使监听器不执行任何操作:

playlistTable.addMouseListener(new MouseAdapter() {
    private boolean ignoreDoubleClicks = false;

    public void mouseClicked(MouseEvent e) {
        if (e.getClickCount() == 2 && !ignoreDoubleClicks) {
            JTable target = (JTable)e.getSource();
            target.removeMouseListener(this);

或

playlistTable.addMouseListener(new MouseAdapter() {
    private boolean ignoreDoubleClicks = false;

    public void mouseClicked(MouseEvent e) {
        if (e.getClickCount() == 2 && !ignoreDoubleClicks) {
                ignoreDoubleClicks = true;
                ...
