I would iterate over all Eclipse workbench instance's widgets. Is there a way to get them all ?

PlatformUI.getWorkbench().getWorkbenchWindows() is something you can
iterate over. Each IWorkbenchWindow has a getShell() which has
getChildren() and for Controls that are composites you can navigate
recursively into their getChildren.

Thanks such is helpful as at least confirms my on going trials. Having some doubts initially as not getting back properly Menu(s) etc ... but sounds some progress about iterating over Controls using getMenu() method.

Now facing concerns trying to retrieve all TreeItem from a Tree. My today result is only providing me children nodes if such are end user visible (i.e. expanded first) ... any advice about ?

PS : I've tried already ((TreeItem) item).setExpanded(true) but not ending with same result as UI based end user tree expansion activity

Note that a tree could potentially be infinitely expandable.

I have a feeling that calling setExpanded doesn't produce a notification
so org.eclipse.jface.viewers.AbstractTreeViewer.hookControl(Control)
wouldn't see an event. So you might need to create an event and notify
the tree so the viewer sees it. But I'm not sure about that.
