org.eclipse.ui.presentationFactories改变Eclipse的外观

原文地址：http://blog.youkuaiyun.com/bradwoo8621/article/details/1584018

<extension point="org.eclipse.ui.presentationFactories"> <factory class="presentation.PresentationFactory" id="presentation.PresentationFactory" name="PresentationFactory"/> </extension> <extension id="product" point="org.eclipse.core.runtime.products"> <product application="application" name="Name"> <property name="preferenceCustomization" value="plugin_customization.ini"/> </product> </extension> 看这段配置.
声明了一个自定义的Presentation. 但是要让这个Presentation生效, 必须是要用Product的声明(因为我是做RCP, 所以Plug-In方式不是太关心, 理论上做Plug-In你也不太应该更改这些个内容).
plugin_customization.ini和plugin.xml在同一个目录下. 内容如下
org.eclipse.ui/presentationFactoryId=presentation.PresentationFactory

org.eclipse.ui/SHOW_TRADITIONAL_STYLE_TABS=false

org.eclipse.ui/DOCK_PERSPECTIVE_BAR=topRight

第一行是说现在使用的是这个表现了, id和xml中的id一致.
第二行比较简单, 就是说现在tab都是圆边的了.

上面是表现的代码, WorkbenchPresentationFactory 其实就是默认的表现. 这个表现更改的东西就是去掉了EditorPart的Tab上右键弹出菜单最后的那个"New Editor"菜单.
