GEF(RCP）开发中碰到的问题及解决方案

1.产生随机颜色

//产生随机颜色
	private Color createRandomColor() {
		return new Color(null,
				(new Double(Math.random() * 128)).intValue() + 128,
				(new Double(Math.random() * 128)).intValue() + 128,
				(new Double(Math.random() * 128)).intValue() + 128);
	}

 

2.RCP程序的启动过程。。了解这个过程可以大概知道一些配置应该在哪做

1）.During the startup of an Eclipse RCP application the Eclipse runtime will evaluate which class is defined via the "org.eclipse.core.runtime.application"extension point.
2）.This class will then be loaded. This class creates and runs a Workbench. The Workbench is configured via a WorkbenchAdvisor. The Workbench will start a WorkbenchWindow which is configured via a WorkbenchWindowAdvisor. This WorkbenchWindow will create the toolbar of the application which can get configured at startup via the ActionBarAdvisor.
3）.Each adviser allow to configure certain behavior of the application, e.g. the WorkbenchAdvisor allows to perform certain actions at startup or shutdown by overriding the methods preStartUp() and preShutdown().
