如何知道何时选择透视rcp

Question

在我的课程中，我正在实现IPerspectiveListener，IPartListener，以便在方法perspectiveActivated（IWorkbenchPage页面，IPerspectiveDescriptor透视图）中激活某些透视图时执行某些操作，并在partActivated（IWorkbenchPart部分）中执行某些操作。但问题是，partActivated（IWorkbenchPart部分）在perspectiveActivated（IWorkbenchPage页面，IPerspectiveDescriptor透视图）之前被调用。看起来上面的方法似乎没有手动调用透视切换。有没有办法实现我提到的。

public class MyClass implements IPerspectiveListener, IPartListener {

 private boolean buttonClicked = false;

        @Override
        public void partActivated(IWorkbenchPart part) {
            try {
                if(buttonClicked){

                     //do something

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

        }

        @Override
        public void partBroughtToTop(IWorkbenchPart part) {
        }

        @Override
        public void partClosed(IWorkbenchPart part) {}

        @Override
        public void partDeactivated(IWorkbenchPart part) {}

        @Override
        public void partOpened(IWorkbenchPart part) {}

        @Override
        public void perspectiveActivated(IWorkbenchPage page, IPerspectiveDescriptor perspective) {
        buttonClicked = true;
        }


        @Override
        public void perspectiveChanged(IWorkbenchPage page, IPerspectiveDescriptor perspective, String changeId) {

        }



    }
