本文整理了Java中org.eclipse.swt.widgets.Tree.setSelection()方法的一些代码示例，展示了Tree.setSelection()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.setSelection()方法的具体详情如下：
包路径：org.eclipse.swt.widgets.Tree
类名称：Tree
方法名：setSelection

Tree.setSelection介绍

[英]Sets the receiver's selection to the given item. The current selection is cleared before the new item is selected, and if necessary the receiver is scrolled to make the new selection visible.

If the item is not in the receiver, then it is ignored.
[中]将接收者的选择设置为给定项目。在选择新项目之前，清除当前选择，如有必要，滚动接收器，使新选择可见。
如果该项不在接收器中，则忽略该项。
