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

Region.isDisposed介绍

[英]Returns true if the region has been disposed, and false otherwise.

This method gets the dispose state for the region. When a region has been disposed, it is an error to invoke any other method (except #dispose()) using the region.
[中]如果区域已被释放，则返回true，否则返回false。
此方法获取区域的dispose状态。当区域已被释放时，使用该区域调用任何其他方法（除了#dispose（））都是错误的。
