SWT中设置TableViewer和TreeViewer成为双击编辑
TableViewerEditor.create(viewer, new DoubleClickColumnViewerEditorActivationStrategy(viewer), ColumnViewerEditor.DEFAULT);
class DoubleClickColumnViewerEditorActivationStrategy extends ColumnViewerEditorActivationStrategy {
?? public DoubleClickColumnViewerEditorActivationStrategy(ColumnViewer viewer) {
??? super(viewer);
?? }
?? /**
?? * 設置編輯器觸發方式
?? */
?? @Override
?? protected boolean isEditorActivationEvent(ColumnViewerEditorActivationEvent event) {
??? boolean singleSelect = ((IStructuredSelection) getViewer().getSelection()).size() == 1;
??? return singleSelect
????? && (event.eventType == ColumnViewerEditorActivationEvent.MOUSE_DOUBLE_CLICK_SELECTION
??????? || event.eventType == ColumnViewerEditorActivationEvent.PROGRAMMATIC || event.eventType == ColumnViewerEditorActivationEvent.TRAVERSAL);
?? }
}
覆盖isEditorActivationEvent方法，加上event.eventType == ColumnViewerEditorActivationEvent.MOUSE_DOUBLE_CLICK_SELECTION条件。

tableViewerColumn_1.setEditingSupport(new EditingSupport(
tableViewerColumn_1.getViewer()) {

@Override

return null;

if (element instanceof Department) {
Department dep = (Department) element;
dep.setDmanager(value.toString());
getViewer().refresh();
}

总结 ?
关键代码就这两行
1：向viewer绑定一种启动编辑的入口（如：是双击、单机、键盘都可以在这个类中区定义）DoubleClickColumnViewerEditorActivationStrategy
TableViewerEditor.create(viewer, new DoubleClickColumnViewerEditorActivationStrategy(viewer), ColumnViewerEditor.DEFAULT);
?
这行代码是为 哪列 设置为可编辑的，并设置一个EditingSupport
tableViewerColumn_1.setEditingSupport(new EditingSupport(
