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

Tree.getItems介绍

[英]Returns a (possibly empty) array of items contained in the receiver that are direct item children of the receiver. These are the roots of the tree.

Note: This is not the actual structure used by the receiver to maintain its list of items, so modifying the array will not affect the receiver.
[中]返回接收器中包含的项的数组（可能为空），这些项是接收器的直接项子项。这些是树的根。
注意：这不是接收方维护其项目列表所使用的实际结构，因此修改数组不会影响接收方。
