我自己的日食编辑器中的“属性视图”事件

Question

I implemented a Properties View in my own editor in eclipse and I start this view using the code:

PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().showView("org.eclipse.ui.views.PropertySheet");

1) Are there listeners that are fired when properties view became visible or invisible, gain ou lost focus?

2) What code I use to know if properties view is closed?

3) What code I use to know if the properties view is opened but not visible? Like this image:

Figure 1

4) How can I know if it is visible and have focus? Like image:

Figure 2

5) And if it is visible and DONT have focus, like:

Figure 3

Answer 1

Use IPartListener2 to listen for all part events.

IPartService partService = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getPartService();

partService.addPartListener(listener);

You will get events for all parts so you will have to check the event is for your part. The listener gets events for all the state changes of a part (open, closed, activated, brought to top, ....)

There is also a very similar IPartListener but IPartListener2 should be used if possible.
