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

Device.getSystemColor介绍

[英]Returns the matching standard color for the given constant, which should be one of the color constants specified in class SWT. Any value other than one of the SWT color constants which is passed in will result in the color black. This color should not be freed because it was allocated by the system, not the application.
[中]返回给定常量的匹配标准颜色，该颜色应为类SWT中指定的颜色常量之一。除了传入的一个SWT颜色常数之外的任何值都将导致黑色。不应释放此颜色，因为它是由系统而不是应用程序分配的。
