过滤后的JTable正确行号

Question

这里是一个try块，它的目的是通过table_job过滤以查找匹配关键字的行。但是，当表模型改变时，我很难获得正确的行索引。它总是选择第一行，即使过滤后的结果显示的行不是第一行。

我知道你可以用fireTableDataChanged()做点什么，但我不确定如何和在哪里做到这一点，在try和catch块或在setLabelText()方法中显示表的内容为. JLabel

try 
{
    sql = "SELECT Job.jobID as 'Job ID', Employer.name as'Company', Job.title as 'Role', Job.description as  'Description', Job.type as 'Type', Job.benefits as 'Benefits', Job.closing as 'Closing Date' FROM Job INNER JOIN Employer ON Job.employerID=Employer.employerID ORDER BY Employer.name";
    pst = conn.prepareStatement(sql);
    rs = pst.executeQuery();
    TableModel model = DbUtils.resultSetToTableModel(rs);
    table_job.setModel(model);
    final TableRowSorter<TableModel> sorter = new TableRowSorter<TableModel>(model);
    table_job.setRowSorter(sorter);               
    searchJob.addActionListener(new ActionListener()
    {
        public void actionPerformed(ActionEvent e) 
        {
            String text = keyword.getText(); 
            if (text.length() == 0) 
            {
                sorter.setRowFilter(null);
            } 
            else 
            {
                sorter.setRowFilter(RowFilter.regexFilter(text));
            }
        }             
    });
}
catch (Exception e) 
{
    e.printStackTrace();                
}
private void setLabelText() 
{
    try 
    {
        String table_click0 = (table_job.getModel().getValueAt(
                row, 0).toString());
        String sqlSt = "SELECT Employer.name, * FROM Job INNER JOIN Employer ON Job.employerID = Employer.employerID WHERE jobID='"+table_click0+"' ";
        //rest of code to Label text...
    }

String table_click0 = (table_job.getModel().getValueAt(row, 0).toString());选择了错误的行，而不是更新后的选择行。我该如何考虑这一点呢?

Answer 1

您可能需要将"行"值转换为模型索引值(如果您的row值是从"视图"的角度检索的)，使用convertRowIndexToModel。所以只需替换

String table_click0 = (table_job.getModel().getValueAt(row, 0).toString());

String table_click0 = table_job.getModel().getValueAt(table_job.
                          convertRowIndexToModel(row), 0).toString());

快速修复:如何在筛选列表中获得实际行

int row=getjTable().getSelectedRow();
if (getjTable().getRowSorter()!=null) {
    row = getjTable().getRowSorter().convertRowIndexToModel(row);
}
