這裏是一個try塊,它用於通過table_job過濾來查找與關鍵字匹配的行。但是,當表模型發生變化時,我正努力獲得正確的行索引。它始終選取第一行,即使篩選結果顯示不是第一行。過濾後的JTable正確的行號
我知道你可以做一些與fireTableDataChanged()
,但我不知道在何處以及如何做到這一點,在try
和catch
塊或setLabelText()
方法,顯示該表爲. 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...
}
內容
String table_click0 = (table_job.getModel().getValueAt(row, 0).toString());
正在拾取錯誤的行,而不是更新的選定行。我怎樣才能考慮到這一點?
1)1號線的空白就足夠了! 2)爲了更快地獲得更好的幫助,請發佈[SSCCE](http://sscce.org/)(將數據庫中的因子排除並對某些數據進行硬編碼)。 3)這可能需要['convertRowIndexToModel(int viewRowIndex)'](http://docs.oracle.com/javase/7/docs/api/javax/swing/JTable.html#convertRowIndexToModel%28int%29)。 –
我想你想看看[JTable#convertRowIndexToModel](http://docs.oracle.com/javase/7/docs/api/javax/swing/JTable.html#convertRowIndexToModel(int))。您可能還想閱讀[如何使用表格,排序和過濾](http://docs.oracle.com/javase/tutorial/uiswing/components/table.html#sorting) – MadProgrammer
@MadProgrammer @Andrew - 謝謝,我應該通過什麼作爲論點。因爲'table_job.convertRowIndexToModel();'單獨是非法的,它應該在'setLabelText()'還是在try catch塊中 – Hoody
