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

GC.getClipping介绍

[英]Returns the bounding rectangle of the receiver's clipping region. If no clipping region is set, the return value will be a rectangle which covers the entire bounds of the object the receiver is drawing on.
[中]返回接收器剪裁区域的边框。如果未设置剪裁区域，则返回值将是一个矩形，覆盖接收器正在绘制的对象的整个边界。
