如何自定义RCP外观

转自：http://www.fengfly.com/plus/view-168171-1.html

 

如果说只需要改变RCP的皮肤可以参照IBM上的Eclipse程序界面美化技术
http://www.fengfly.com/plus/view-168476-1.html
如 果想自定义RCP的外观就得用到presentationFactories，presentationFactories是eclipse为 editor以及view提供的一个外观工厂，在eclipse官网上推荐的书中就提到过这么个工厂，今天再看MP3MANAGER源代码的时候发现实现 起来也挺简单的，不过我还是习惯eclipse风格，所以没将应用的外观改变，之前也一直在寻找改变RCP外观的方法，昨天网友告诉我IBM上有我就去看 了下，就是简单的变换了图片和背景颜色，也就是个SWT的皮肤而已，下面我就直接贴代码演示presentationFactories的实现方法
首 先就是Presentation 类：

Java代码

我这里在提供两种调用的方法
方法一：
在plugin.xml中加入

Java代码

1. <extension   
2.         point= "org.eclipse.ui.presentationFactories" >   
3.      <factory   
4.             class = "com.siemens.ct.mp3m.ui.presentation.PresentationFactory"   
5.            id= "com.siemens.ct.mp3m.ui.presentation.PresentationFactory"   
6.            name= "Siemens CT Presentation" />   
7.   </extension>  

 <extension
         point="org.eclipse.ui.presentationFactories">
      <factory
            class="com.siemens.ct.mp3m.ui.presentation.PresentationFactory"
            id="com.siemens.ct.mp3m.ui.presentation.PresentationFactory"
            name="Siemens CT Presentation"/>
   </extension>

第二种方法就是在ini文件中加入

Java代码

1. org.eclipse.ui/presentationFactoryId=com.siemens.ct.mp3m.ui.presentation.PresentationFactory  

org.eclipse.ui/presentationFactoryId=com.siemens.ct.mp3m.ui.presentation.PresentationFactory

代码不难摘自MP3M，相信大家能理解
