Question

我为Eclipse编写了一个插件，它是一个带有一些视图的透视图。关闭Eclipse时，我在重置透视图时遇到问题。我已经到了可以在视图上释放所有内容并隐藏视图的点，但是当你再次启动Eclipse时，我隐藏的视图又回来了。当用户关闭Eclipse时如何获得重置的透视图？

我使用org.eclipse.ui.PerspectiveAdapter来提醒观点。每次打开透视图时都要检查某些内容采取行动打开或关闭某些观点。

我在Activator中注册了PerspectiveAdapter。 start（BundleContext上下文）事件调用方法。

我的breif Activator代码如下。

/*
 * (non-Javadoc)
 * @see org.eclipse.ui.plugin.AbstractUIPlugin#start(org.osgi.framework.BundleContext)
 */
public void start(BundleContext context) throws Exception {
    super.start(context);
    plugin = this;
    .......
    ll = new fomomentumplugin.perspectives.LicenseListener();
    IWorkbench wbench = PlatformUI.getWorkbench();
     IWorkbenchWindow window =  wbench.getActiveWorkbenchWindow() ;
     window.addPerspectiveListener(ll);
     ...........
}


and 

public class LicenseListener extends PerspectiveAdapter {

public  void perspectiveOpened(IWorkbenchPage page, IPerspectiveDescriptor perspective) {
    String componentName = "FOMomentum";
    if(perspective.getId().equals("org.softools.FOMomentumPLugin.FO")){
        if(Activator.checkLicense == null || !Activator.checkLicense.isValidLicense(componentName)){
            System.out.println("org.softools.FOMomentumPLugin.FO perspective Activated with no license found message !");
        //page.resetPerspective();
            hideViews(page);
        }
        else showViews(page);
    }
}

public  void perspectiveActivated(IWorkbenchPage page, IPerspectiveDescriptor perspective) {
    String componentName = "FOMomentum";
    if(perspective.getId().equals("org.softools.FOMomentumPLugin.FO")){
        if(Activator.checkLicense == null || !Activator.checkLicense.isValidLicense(componentName)){
            System.out.println("org.softools.FOMomentumPLugin.FO perspective Activated with no license found message !");
        //page.resetPerspective();
            hideViews(page);
        }
        else showViews(page);
    }

}

private void hideViews(IWorkbenchPage page){
    IViewPart momentum = page.findView("fomomentumplugin.views.FOMomentumView") ;
        if(momentum != null){
            ((fomomentumplugin.views.FOMomentumView)momentum).removeCalendarCombo();
            page.hideView(momentum);
        }

    IViewPart momentumDetail = page.findView("fomomentumplugin.views.FOMomentumDetailView") ;
    page.hideView(momentumDetail);
    IViewPart movingAverageview = page.findView("FOCallCandlebarView") ;
    page.hideView(movingAverageview);
    IViewPart priceVolumeView = page.findView("FOMomentumPLugin.FOPutCandlebarView") ;
    page.hideView(priceVolumeView);
}

private void showViews(IWorkbenchPage page){
    try {
        page.showView("fomomentumplugin.views.FOMomentumView");
        page.showView("fomomentumplugin.views.FOMomentumDetailView");
        page.showView("FOCallCandlebarView");
        page.showView("FOMomentumPLugin.FOPutCandlebarView");
    } catch (PartInitException e) {
        e.printStackTrace();
    }       
}

}

我希望这会有所帮助。
