How to tell if a view is visible/hidden or not? [message #511223]

I have two views ViewA and ViewB that are in a stack relation (ViewB is displayed in the right side of ViewA). Obviously only one of these two views is visible and the other one is hidden.

I want to know which view is hidden so that I can make it visible by programatically calling the showView(view_descriptor.getId()) on the active IWorkbenchPage page.

So far I was able to do this: in ViewB I registered a IPartListener2 and keep a boolean about the visibility of the view but I do not know how to make this info available in my ViewSwitcherMenu class that extends ContributionItem (I am trying to used a dynamic menu).

Is there another simpler way to find out if a view is visible or not?
From the active page I can get the array of the available view references (IViewReference[]) and isolate the view I am interested in but I do not know if it is hidden or not.

Any help would be greatly appreciated.

Time is what you make of it.

Hi Catalin,

I hope somebody has some better ideas but this is what I can think off:

can't you just call showview and be done with it?

If not then you can store the result of your partlistener in a global thing
like the dialog settings or a static variable (e.g.
UTIL.get/setVisibleViewList()). You can also let your view implement an
interface and set a listener on one of your view controls in
createpartcontrol that will provide the value through the interface method.

Here is an article about providing state to the workbench with an
isourceprovider

Hello Wim

I found what I was looking for but I do not like it because it uses org.eclipse.ui.internal class.

For any view I can get the IViewReference. If you cast it to WorkbenchPartReference then you will be able to use the getVisible() method that will tell if the view is visible or not.

In my particular case the layout of my perspectives is fixed and the views have no minimize / maximize or close buttons.

I started with this example http://eclipsesource.com/blogs/2009/03/31/replacing-the-pers pective-switcher-in-rcp-apps/ and I wanted to modify it for stacked views also.

Time is what you make of it.

Did you try org.eclipse.ui.IWorkbenchPage.isPartVisible(IWorkbenchPart)?
