将2个jface TreeViewers垂直对齐到特定元素 [英] Vertical align 2 jface TreeViewers to specific element

问题描述

我在页面上有两个 TreeViewer 对象（两列，每列一个 TreeViewer ），我

I have two TreeViewer objects on a page (2 columns, one TreeViewer in each column), and I want to vertically align a tree when the other is scrolled or selected.

import org.eclipse.jface.viewers.TreeViewer;
import org.eclipse.swt.widgets.Tree;

我认为解决方案应类似于

I think the solution should look something like

treeViewer.addSelectionChangedListener(new ISelectionChangedListener() {
  @Override
  public void selectionChanged(SelectionChangedEvent arg0) {
     TreeViewer mirrorTree = (treeViewer == treeVwrSource ? treeVwrTarget : treeVwrSource);
     // find position of selected element (element x) in treeViewer
     // set position of element x in mirrorTree, it is already selected.
  }
});

有什么建议吗？
