SWT Table：無法從TableEditor創建的表中檢索數據

Question

我從創建的表中檢索數據時遇到問題。它顯示一個複選框，字符串（從首先添加的all_mapping_objects獲取）並下拉組合值爲0.0到1.0。如何在表格中編輯完所有值後檢索所有值，例如複選框布爾值，字符串值和組合值。

嘗試了TableItem[] items = table.getItems()的一些變化，但我只收回空值。

final Table table = new Table(sectionsInfo, SWT.BORDER | SWT.MULTI | SWT.H_SCROLL | SWT.V_SCROLL); 
       table.setLinesVisible(true); 
       InfogridData = new GridData(); 
       InfogridData.horizontalSpan = 4; 
       InfogridData.horizontalAlignment = GridData.BEGINNING; 
       InfogridData.horizontalAlignment = GridData.FILL; 
       InfogridData.grabExcessHorizontalSpace = true; 
       InfogridData.verticalAlignment = GridData.BEGINNING; 
       InfogridData.verticalAlignment = GridData.FILL; 
       InfogridData.grabExcessVerticalSpace= true; 


       TableColumn column = new TableColumn(table, SWT.NONE); 
       column.setWidth(500); 

       TableColumn column2 = new TableColumn(table, SWT.NONE); 
       column2.setWidth(50); 

       table.setLayoutData(InfogridData); 


       for (int i = 0; i < all_mapping_objects.size(); i++) { 
       new TableItem(table, SWT.NONE); 
       } 
       TableItem[] items = table.getItems(); 



       for (int i = 0; i < items.length; i++) { 
       TableEditor editor = new TableEditor(table); //defines editor which controls objects put in 


       CCombo combo = new CCombo(table, SWT.NONE | SWT.READ_ONLY); 
       editor.grabHorizontal = true; 


        for (float me = 0; me <= 10; me++) { 
        combo.add("" + me/10);      
        } 

       combo.setText("1.0"); 

       editor.setEditor(combo, items[i], 1); // sets the column 
       editor = new TableEditor(table); 


       Button button = new Button(table, SWT.CHECK); 


       button.setText(all_mapping_objects.get(i).getTextf()); // mapping objects written to the table 

       button.pack(); 
       editor.minimumWidth = button.getSize().x; 
       editor.horizontalAlignment = SWT.LEFT; 
       editor.setEditor(button, items[i], 0); // sets the column 



       }

您應該CCombo上Button (SWT.CHECK)使用SelectionListener中，同樣。我建議你開始使用TableViewer代替SWT表。
