Eclipse RCP开发剪辑之perspective

 一、使用扩展点定义透视图和里面的view有两种方式处理，分别是：

1、使用org.eclipse.ui.perspectives 扩展点定义透视图的相关信息，使用org.eclipse.ui.views定义view的相关信息。定义完成，在一个实现了 IPerspectiveFactory接口的类里添加view，在添加的时候定义view的布局，如下：

         point = " org.eclipse.ui.perspectives " >
                   class = " com.ibm.demo.saic.MainPerspective "
            id = " com.ibm.demo.saic.MainPerspective "
            name = " MainPerspective " />
  

         point = " org.eclipse.ui.views " >
                   class = " com.ibm.demo.saic.ui.views.TreeView "
            id = " com.ibm.demo.saic.ui.views.TreeView "
            name = " TreeView " />
                   class = " com.ibm.demo.saic.ui.views.WelcomeView "
            id = " com.ibm.demo.saic.ui.views.WelcomeView "
            name = " WelcomeView " />

public class MainPerspective implements IPerspectiveFactory ...{
 public static String ID="com.ibm.demo.saic.MainPerspective";
 public void createInitialLayout(IPageLayout layout) ...{
  layout.setEditorAreaVisible(false);
  
  layout.addView(TreeView.ID, IPageLayout.TOP,
    0.25f, layout.getEditorArea());
  
  layout.setEditorAreaVisible(false);
  /**//*layout.addView(LoginView.ID,IPageLayout.LEFT,
    1f,layout.getEditorArea());*/
  
  layout.addView(WelcomeView.ID,IPageLayout.LEFT,
    1f,layout.getEditorArea());
  
  IViewLayout vl=layout.getViewLayout(WelcomeView.ID);
  //设置View不可关闭
  layout.getViewLayout(WelcomeView.ID).setCloseable(false);
  //设置View不可移动
  layout.getViewLayout(WelcomeView.ID).setMoveable(false);
 }
}

2, 使用org.eclipse.ui.perspectiveExtensions扩展点，向某个perspective里添加view，并设置布局。(说明：需要先定义好perspective和view)

         point="org.eclipse.ui.perspectiveExtensions">
     
        
               closeable="false"
               id="com.ibm.demo.saic.ui.views.LoginView"
               moveable="false"
               ratio="1f"
               relationship="left"
               relative="org.eclipse.ui.editorss"
               visible="true"/>  

public   class  LoginPerspective  implements  IPerspectiveFactory  ... {
 public static String ID="com.ibm.demo.saic.LoginPerspective";
 
 public void createInitialLayout(IPageLayout layout) ...{
  layout.setEditorAreaVisible(false);
 }

}

二、如何关闭perspective
关闭当前perspective，并打开一个新的perspective:

IWorkbench w = PlatformUI.getWorkbench();

ActionFactory.IWorkbenchAction closePerspectiveAction
=  ActionFactory.CLOSE_PERSPECTIVE.create(w.getActiveWorkbenchWindow());
closePerspectiveAction.run();

try   ... {
PlatformUI.getWorkbench().showPerspective("com.ibm.demo.saic.ui.views.NextPerspective", w.getActiveWorkbenchWindow());
}   catch  (WorkbenchException e)  ... {
e.printStackTrace();
}

上面是调用的系统的action，具体实现如下：

IWorkbench w = PlatformUI.getWorkbench();
IPerspectiveRegistry pr = w.getPerspectiveRegistry() ;
IPerspectiveDescriptor persdes = pr.findPerspectiveWithId( " perspectiveID " );

WorkbenchPage p = (WorkbenchPage)w.getActiveWorkbenchWindow().getActivePage();
Perspective persp  =  p.getActivePerspective();
p.closePerspective(persdes, false , false );

try   ... {
w.showPerspective("nextperspectiveID", w.getActiveWorkbenchWindow());
}   catch  (WorkbenchException e)  ... {
e.printStackTrace();
}
