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

Color.isDisposed介绍

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

This method gets the dispose state for the color. When a color has been disposed, it is an error to invoke any other method (except #dispose()) using the color.
[中]如果颜色已被处理，则返回true，否则返回false。
此方法获取颜色的dispose状态。处理颜色后，使用颜色调用任何其他方法（除了#dispose（））都是错误的。

/**
 * Free the managed resource if it hasn't already been done and if this is not a system color
 *
 */
public void dispose() {
 // System color and already disposed off colors don't need to be disposed!
 if ( !systemColor && !color.isDisposed() ) {
  color.dispose();
 }
}
