关于表的行选择问题？

Question

在表中
int[] selectedRows;  
jTable.addMouseListener(new MouseAdapter() {
    public void mousePressed(MouseEvent evt) {    }    public void mouseReleased(MouseEvent evt) {
        
    }
}//行选择完成后，拖动所选择的行
jTableSourceFile.addMouseMotionListener(new MouseMotionAdapter() {
    public void mouseDragged(MouseEvent e) {
        //在 addMouseListener 按下及弹起中已得到selectedRows
        
        if(selectedRows!= null && selectedRows.length > 0)
        {
            jTableQualifyPage.clearSelection();
            for(int i = 0; i < selectedRows.length; i++)
            {
                jTableQualifyPage.addRowSelectionInterval(selectedRows[i],selectedRows[i]);
            }
        }
    }
}selectedRows里的行索引数据是正确的一个奇怪的问题：
    在工程中，有俩个界面用到了，一个表中拖动后界面显示是正确的，二另一个表中拖动后界面选择不正确呵呵！~怪怪的问题

        jTableSourceFile.addMouseListener(new MouseAdapter() {
            boolean contain = false;
            public void mousePressed(MouseEvent evt) {

晕死，都什么逻辑啊表格拖拽设置一个TransferHandler就行了table.setDragEnabled(true);
table.setTransferHandler(new TableTransferHandler());//自定义一个Handler

Answer 3

恩！~
我试试你说的那样看看。我刚才深入看了下拖拽源的代码，确实没必要写那么。我刚刚工作没多久，参与这个项目时已经成规模了，但里面N多的bug
swing方面很多的不懂。问下，你也是搞swing方面的吗？

Answer 4

几年之前是做Swing相关的，现在不是了 ：）
