在我的RCP应用程序中，TreeViewer左侧有一个用于导航的视图，右侧有一个用于视图的文件夹。透视图看起来像这样：

public void createInitialLayout(IPageLayout layout) {
    layout.setEditorAreaVisible(false);
    layout.setFixed(false);

    layout.addStandaloneView(NavigationView.ID, false, IPageLayout.LEFT, 0.7f, layout.getEditorArea());

    right = layout.createFolder("right", IPageLayout.RIGHT, 0.3f, "com.my.app.views.browser.navigation");


    layout.getViewLayout(WallpaperView.Id).setCloseable(false);//dummy view to keep the folder from closing
    layout.getViewLayout(WallpaperView.Id).setMoveable(false);

    right.addView(WallpaperView.Id);        
    //add some placeholders for the potential views
    right.addPlaceholder(DefaultAdminView.ID+":*");

}

我想根据用户在导航树中选择的内容打开不同的视图。认为这并不难。我的导航树视图：

tree = new TreeViewer(composite);
tree.setContentProvider(new BrowserNavigationTreeContentProvider());
tree.setLabelProvider(new BrowserNavigationTreeLabelProvider());
tree.setInput(UserProfileAdvisor.getProject());

//register Mouselistener for doubleclick events
tree.addDoubleClickListener(new IDoubleClickListener(){

    @Override
    public void doubleClick(DoubleClickEvent event) {
        TreeSelection ts = (TreeSelection) event.getSelection();
        Object selectedItem = ts.getFirstElement();
        String viewId = DefaultAdminView.ID;

         //set viewId depending on the selectedItem.class
        try {
            PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().showView(viewId, String.valueOf(++viewCounter), IWorkbenchPage.VIEW_ACTIVATE);

        } catch (PartInitException e) {
            ILogHelper.error("The view for the selected object could not be opened", e);
        }
    }

});

这似乎很好。仅有一个小问题：我需要以某种方式将对象（例如，selectedItem）传递给我的视图，以使用户与其内容进行交互。我怎么做？

我看到了一些示例，其中一些同事编写了自己的视图，并将其放置在右侧。然后，他们添加CTabFolder，实例化视图并手动添加。有没有更聪明的解决方案？
