本文整理了Java中org.eclipse.swt.graphics.Color类的一些代码示例，展示了Color类的具体用法。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。Color类的具体详情如下：
包路径：org.eclipse.swt.graphics.Color
类名称：Color

Color介绍

[英]Instances of this class manage the operating system resources that implement SWT's RGB color model. To create a color you can either specify the individual color components as integers in the range 0 to 255 or provide an instance of an RGB or RGBA.

Application code must explicitly invoke the Color.dispose() method to release the operating system resources managed by each instance when those instances are no longer required.
[中]此类的实例管理实现SWT的RGB颜色模型的操作系统资源。要创建颜色，可以将各个颜色组件指定为0到255范围内的整数，也可以提供RGB或RGBA的实例。
当不再需要由每个实例管理的操作系统资源时，应用程序代码必须显式调用Color.dispose()方法来释放这些资源。

代码示例

/**
 * Get the image for when all other fallbacks have failed.  This is an image
 * drawn on the canvas, a square with a red X.

 * @return the missing image
