我有一个使用 NetBeans IDE 的桌面应用程序,该应用程序有一个JTable
显示来自 lucene 搜索操作的数据。
每次进行新搜索时,该表都会将新搜索结果附加到先前的搜索结果中。我想要的是表格用新的搜索结果替换任何现有的搜索结果。为了让表中的词刷新并显示新的搜索结果。
任何可用的建议
这是数据模型的代码片段
public class MyTableModel extends AbstractTableModel {
private Vector<Vector<String>> dataList = new Vector<>();
private String[] header = { "ID","SUBJECT","LETTTER FROM","LETTER DATE","DATE RECEIED",
"REMARKS","DATE DISPATCHED","DESTINATION OFFICE"};
public Vector<Vector<String>> getDataList() {
return dataList;
}
public void setDataList(Vector<Vector<String>> dataList) {
this.dataList = dataList;
fireTableDataChanged();
}
public void setHeader(String[] header) {
this.header = header;
}
public String[] getHeader() {
return header;
}
@Override
public int getRowCount() {
return dataList.size();
}
@Override
public int getColumnCount() {
return header.length;
}
@Override
public String getColumnName(int col) {
return header[col];
}
@Override
public Object getValueAt(int row, int col) {
return dataList.get(row).get(col);
}
}
此代码将搜索结果传递给数据模型类
private void searchButtonActionPerformed(java.awt.event.ActionEvent evt) {
try {
searchField = searchTextField.getText();
if(!searchField.isEmpty())
{
matrix = dbs.searchDatabase(searchField + "*");
myModel.setDataList(matrix);
}
} catch (CorruptIndexException ex) {
Logger.getLogger(GNSSJFrame.class.getName()).log(Level.SEVERE, null, ex);
} catch (LockObtainFailedException ex) {
Logger.getLogger(GNSSJFrame.class.getName()).log(Level.SEVERE, null, ex);
} catch (IOException | ParseException ex) {
Logger.getLogger(GNSSJFrame.class.getName()).log(Level.SEVERE, null, ex);
}
}
