Question

我在从我创建的表中检索数据时遇到问题。它显示一个复选框，字符串（取自首先添加的all_mapping_objects）和下拉组合，值为0.0到1.0。如何在表中编辑后检索所有值，即复选框boolean，string value和combo value。

尝试了TableItem[] items = table.getItems()的一些变体，但我只回到空值。

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



              }

您应该在Button ( SWT.CHECK)上使用SelectionListener，对CCombo也是如此。我建议您开始使用TableViewer而不是使用SWT表。
