本文整理了Java中org.eclipse.swt.widgets.Tree.addSelectionListener()方法的一些代码示例，展示了Tree.addSelectionListener()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Tree.addSelectionListener()方法的具体详情如下：
包路径：org.eclipse.swt.widgets.Tree
类名称：Tree
方法名：addSelectionListener

Tree.addSelectionListener介绍

[英]Adds the listener to the collection of listeners who will be notified when the user changes the receiver's selection, by sending it one of the messages defined in the SelectionListener interface.

When widgetSelected is called, the item field of the event object is valid. If the receiver has the SWT.CHECK style and the check selection changes, the event object detail field contains the value SWT.CHECK. widgetDefaultSelected is typically called when an item is double-clicked. The item field of the event object is valid for default selection, but the detail field is not used.
[中]将侦听器添加到侦听器集合中，当用户更改接收者的选择时，将通过向其发送SelectionListener界面中定义的消息之一来通知这些侦听器。
调用widgetSelected时，事件对象的项目字段有效。如果接收器具有SWT.CHECK样式，并且检查选择发生更改，则事件对象详细信息字段包含值SWT.CHECK。双击项目时通常会调用widgetDefaultSelected。事件对象的“项目”字段对于默认选择有效，但不使用“详细信息”字段。

    TreeItem[] items = tree.getSelection();
    for ( int i = 0; i < items.length; i++ ) {
     String[] path2 = ConstUI.getTreeStrings( items[i] );

      doubleClick.action( treeItem );

  // Clean up when we do a refresh too.

   public void widgetDisposed( DisposeEvent disposeEvent ) {
    tree.removeSelectionListener( selectionAdapter );
   }
