本文整理了Java中org.eclipse.swt.widgets.Item类的一些代码示例，展示了Item类的具体用法。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。Item类的具体详情如下：
包路径：org.eclipse.swt.widgets.Item
类名称：Item

Item介绍

[英]This class is the abstract superclass of all non-windowed user interface objects that occur within specific controls. For example, a tree will contain tree items. Styles: (none) Events: (none)
[中]此类是特定控件中出现的所有非窗口用户界面对象的抽象超类。例如，树将包含树项。样式：（无）事件：（无）
