JTableCombo價值觀不改變運行時

Question

其實我有一個在JTable一個Column有ComboBox，我想是改變JTable「在運行時小號ComboBox的值，在CheckBox值更改事件，我打電話的功能，爲我帶來了新的價值，但值沒有變化。 util.RefreshReplicatedDataAndHeader(true,objVector,-1,this, jScroll_ProductStone.getName());是獲取我的函數JTable數據。它叫AddComboBoxForJTable。我提供了我用於更改組合值和實際功能的代碼的一部分，它使JTable與更改後的值組合在一起。非常感謝您提供解決方案。

if (thaiFlag) 
{  
    combo_Id_Name_tbl.add("Setting");// Table Name 
    combo_Id_Name_tbl.add("SetID"); //Combo Id 
    combo_Id_Name_tbl.add("SetThaiName");// Combo Val 
    combo_Id_Name_tbl.add("Setting"); // Identifer Of Table For Two Combo FromSameTable 
    combo_Id_Name_tbl.add("Please select required Setting For Selected Lot"); 
    combo_Id_Name_tbl.add("SetID");// ColId For Selected Combo 
    combo_Id_Name_tbl.add("SetName"); // Col Val For Selected Combo 
    combo_Id_Name_tbl.add("N/A"); // Col Id For Non JTable Selected Cobo 
    combo_Id_Name_tbl.add("N/A"); // Combo Filter Col Name 
    combo_Id_Name_tbl.add("N/A"); // Combo Filter Col Value 
    ColId_Val_Identifier_TableName_ForCombo.add(combo_Id_Name_tbl);  
} 
else 
{ 
    combo_Id_Name_tbl.add("Setting");// Table Name 
    combo_Id_Name_tbl.add("SetID"); //Combo Id 
    combo_Id_Name_tbl.add("SetName");// Combo Val 
    combo_Id_Name_tbl.add("Setting"); // Identifer Of Table For Two Combo From Same Table 
    combo_Id_Name_tbl.add("Please select required Setting For Selected Lot"); 
    combo_Id_Name_tbl.add("SetID");// ColId For Selected Combo 
    combo_Id_Name_tbl.add("SetName"); // Col Val For Selected Combo 
    combo_Id_Name_tbl.add("N/A"); // Col Id For Non JTable Selected Cobo 
    combo_Id_Name_tbl.add("N/A"); // Combo Filter Col Name 
    combo_Id_Name_tbl.add("N/A"); // Combo Filter Col Value 
    ColId_Val_Identifier_TableName_ForCombo.add(combo_Id_Name_tbl); 
} 


    TableColumnModel tcm = jtblSizeInfo.getColumnModel(); 
    objVector=null; 
    objVector=new Vector<Object>(); 
    objVector.add(data_SizeInfo); 
    objVector.add(header_SizeInfo); 
    objVector.add(data_ForSave_SizeInfo); 
    objVector.add(colHeader_ForSave_SizeInfo); 
    objVector.add(AddedCols_Name_Pos); 
    objVector.add(ColId_Val_Identifier_TableName_ForCombo); 
    objVector.add(tcm); 
    Vector<Object> objResultVector = util.RefreshReplicatedDataAndHeader(true, objVector,-1, this, jScroll_ProductStone.getName()); 


    data_SizeInfo =(Vector<Vector<String>>)objResultVector.get(0) ; 
    header_SizeInfo=(Vector<String>)objResultVector.get(1) ; 
    data_ForSave_SizeInfo =(Vector<Vector<String>>)objResultVector.get(2) ; 
    colHeader_ForSave_SizeInfo=(Vector<String>)objResultVector.get(3) ; 
    TableColumnModel tcm1 = (TableColumnModel)objResultVector.get(4); 



    // Column Model Is used to get the Columns And Action Listnner Added In Utility Form 
    Vector<TableColumn> vtc = new Vector<TableColumn>(); 
    int colCount_Ref = tcm.getColumnCount(); 

    for (int i=0;i<colCount_Ref;i++) 
    { 
     vtc.add(tcm.getColumn(i));   
    } 


    for (int i=0;i<vtc.size();i++) 
    {    
     tcm.removeColumn(vtc.get(i)); 
    } 

    for (int i=0;i<tcm1.getColumnCount();i++) 
    { 
     tcm.addColumn(tcm1.getColumn(i)); 
    } 
    jtblSizeInfo.setColumnModel(tcm); 
    jtblSizeInfo.repaint(); 
    jtblSizeInfo.revalidate(); 
} 

的代碼添加組合框的JTable是直接跟

public void AddComboBoxForJTable(int colIndex,Vector<String>vectTable_JtblColIdVal_ComboIdentify, int selectedRow,Object   currentFormObj,String currentJScrollPane) 
{ 
    ////// JComboBox comboBox=null; 
    try 
    { 
     String tableName =vectTable_JtblColIdVal_ComboIdentify.get(0); 
     String comboId =vectTable_JtblColIdVal_ComboIdentify.get(1); 
     String comboValue =vectTable_JtblColIdVal_ComboIdentify.get(2); 
     String comboIdentifier =vectTable_JtblColIdVal_ComboIdentify.get(3); 
     String comboFilterColName =vectTable_JtblColIdVal_ComboIdentify.get(8); 
     String comboFilterColValue =vectTable_JtblColIdVal_ComboIdentify.get(9); 
     Vector<String> comboFilter =new Vector<String>(); 
     comboFilter.add(comboFilterColName); 
     comboFilter.add(comboFilterColValue); 

     Vector<Vector<String>> comboData=new Vector<Vector<String>>(); 
     //JComboBox comboBox; 
     DBEngine dbe = new DBEngine(); 
     if (comboFilterColName.equals("N/A")) 
     { 
      comboData = dbe.getComboData(tableName, comboId, comboValue,comboValue); 
     } 
     else 
     { 
      comboData = dbe.getComboData(tableName, comboId, comboValue,comboValue,comboFilter); 
     } 

     Vector model = new Vector();  

     for (int i =0;i<comboData.size();i ++) 
     {      
      // model.addElement(new CustomizedComboBox(3, "train")); 
      String id =comboData.get(i).elementAt(0).toString(); 
      String data= comboData.get(i).elementAt(1).toString(); 
      Item_ it= new Item_(id,data); 

      model.addElement(it);   

     } 


     JComboBox comboBox = new JComboBox(model);  


     MyActionListenerForJtableCombo_Utility actionListener = new MyActionListenerForJtableCombo_Utility( 
     vectTable_JtblColIdVal_ComboIdentify, selectedRow, currentFormObj, currentJScrollPane);  
     actionListener.util=this; 
     actionListener.tableName=tableName; 

     comboBox.addActionListener(actionListener); 




     // DefaultTableModel tblModel = (DefaultTableModel)jtblUtilities.getModel(); 
     TableColumn column= jtbl_General.getColumnModel().getColumn(colIndex); 
     column.setCellEditor(new javax.swing.DefaultCellEditor(comboBox)); 
    } 
    catch (Exception ex) 
    { 
     ex.printStackTrace(); 
     // Logger.getLogger(ComboBoxEditor.class.getName()).log(Level.SEVERE, null, ex); 
    } 
}

表模型內部真的再也不能把Swing組件。從正確的重新繪製到傳遞鍵和鼠標事件，都存在着許多問題。您要做的是聲明JComboBox as a default editor。我認爲它甚至是字符串數組的默認編輯器（比如JCheckBox是布爾值的默認編輯器）。所以你只需要把這些數組放在模型中，讓JTable的魔術爲你做所有的工作
