SWT如何使表格具有单击突出显示整行并双击编辑单元格的功能？

吉安·卢卡·斯帕达佛拉（Gian Luca Spadafora）：

SWT新手在这里。因此，我想要的是能够突出显示整行，并能够选择多行，并使其能够双击编辑单元格。focusCellManager是否必要？相关代码段：

EditorActivationEvent

final ColumnViewerEditorActivationStrategy actSupport = 
   new ColumnViewerEditorActivationStrategy(this)
   {
     @Override
     protected boolean isEditorActivationEvent
     (ColumnViewerEditorActivationEvent event)
       {
         return event.type == 
             ColumnViewerEditorActivationEvent.TRAVERSAL
             || event.eventType == 
         ColumnViewerEditorActivationEvent.MOUSE_DOUBLE_CLICK_SELECTION
             || event.eventType == 
             ColumnViewerEditorActivationEvent.KEY_PRESSED
             || event.eventType ==
             ColumnViewerEditorActivationEvent.PROGRAMMATIC;
       }
  };

创建TableViewerEditor

TableViewerEditor.create(this,
    mgr,
    actSupport,
    ColumnViewerEditor.TABBING_HORIZONTAL|
    ColumnViewerEditor.TABBING_MOVE_TO_ROW_NEIGHBOR|
    ColumnViewerEditor.TABBING_VERTICAL|
    ColumnViewerEditor.KEYBOARD_ACTIVATION);

mgr（focusCellManager）的代码：

focusCellOwnerDrawHighlighter drawHighlighter = new FocusCellOwnerDrawHighlighter(this);

final TableViewerFocusCellManager mgr = new TableViewerFocusCellManager(this, null);

tableViewer（由于另一个类扩展了tableViewer，因此在以前的摘要中没有出现，而我们使用另一个类，因此我不想让您感到困惑）：

TableViewer vwr = new TableViewer(tableComposite,SWT.BORDER|SWT.FULL_SELECTION|SWT.MULTI);

greg-449：

使用EditingSupport上，使用下列TableViewerEditor合并表中的列似乎为我工作：

TableViewer viewer = new TableViewer(tableComp, SWT.V_SCROLL | SWT.H_SCROLL | SWT.BORDER | SWT.FULL_SELECTION);

ColumnViewerEditorActivationStrategy actSupport = new ColumnViewerEditorActivationStrategy(viewer) {
  @Override
  protected boolean isEditorActivationEvent(final ColumnViewerEditorActivationEvent event) {
    return event.eventType == ColumnViewerEditorActivationEvent.TRAVERSAL
        || event.eventType == ColumnViewerEditorActivationEvent.MOUSE_DOUBLE_CLICK_SELECTION
        || event.eventType == ColumnViewerEditorActivationEvent.KEY_PRESSED
        || event.eventType == ColumnViewerEditorActivationEvent.PROGRAMMATIC;
  }
};

int feature = ColumnViewerEditor.TABBING_MOVE_TO_ROW_NEIGHBOR | ColumnViewerEditor.TABBING_HORIZONTAL
    | ColumnViewerEditor.KEYBOARD_ACTIVATION
    | ColumnViewerEditor.TABBING_CYCLE_IN_VIEWER;

TableViewerEditor.create(viewer, actSupport, feature);
