Eclipse RCP，改变视角

Question

我需要的是：一个带有欢迎页面的应用程序，然后切换到另一个视角。为了切换视角，使用了以下代码：

public class SwitchPerspectiveAction extends Action {

    public void run() {
        if (PlatformUI.getWorkbench() != null) {
            try {
                PlatformUI.getWorkbench().showPerspective(Perspective.ID, PlatformUI.getWorkbench().getActiveWorkbenchWindow());
            } catch (WorkbenchException e) {
                e.printStackTrace();
            }
        }
    }   
}

什么都没发生 :-(

已解决：

public class SwitchPerspectiveAction extends Action {

    public void run() {
        if (PlatformUI.getWorkbench() != null) {
            try {
                IPerspectiveDescriptor descriptor = window.getWorkbench()
                    .getPerspectiveRegistry()
                    .findPerspectiveWithId(Perspective.ID);

                PlatformUI.getWorkbench().getActiveWorkbenchWindow()
                    .getActivePage().setPerspective(descriptor);

            } catch (WorkbenchException e) {
                e.printStackTrace();
            }
        }
    }   
}
