本文整理了Java中org.eclipse.jface.viewers.TreePath.getParentPath()方法的一些代码示例，展示了TreePath.getParentPath()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。TreePath.getParentPath()方法的具体详情如下：
包路径：org.eclipse.jface.viewers.TreePath
类名称：TreePath
方法名：getParentPath

TreePath.getParentPath介绍

[英]Returns a copy of this tree path with one segment removed from the end, or null if this tree path has no segments.
[中]返回此树路径的副本，其中一个段已从末尾删除，如果此树路径没有段，则返回null。
