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

List.getSelection介绍

[英]Returns an array of Strings that are currently selected in the receiver. The order of the items is unspecified. An empty array indicates that no items are selected.

Note: This is not the actual structure used by the receiver to maintain its selection, so modifying the array will not affect the receiver.
[中]返回接收器中当前选定的String个数组。项目的顺序未指定。空数组表示未选择任何项。
注意：这不是接收器用于保持其选择的实际结构，因此修改阵列不会影响接收器。
