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

GC.getGCData介绍

[英]Returns the GCData.

IMPORTANT: This method is not part of the public API for GC. It is marked public only so that it can be shared within the packages provided by SWT. It is not available on all platforms, and should never be called from application code.
[中]返回GCData。
重要提示：此方法不是GC的公共API的部分。它被标记为public，以便可以在SWT提供的包中共享。它并非在所有平台上都可用，并且永远不应从应用程序代码中调用。
