Open View, and bring it to front? [message #301183]

R3.1.1, WinXP

To open a view I know how to do:

PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().showView() ...

But if the user has previously "tabbed" (or whatever is the correct term) the view in question
behind another View, this does *not* bring the view to the front. I've tried showView(ID_VIEW),
showView(ID_VIEW, null, IWorkbenchPage.VIEW_ACTIVATE), and showView(ID_VIEW, null,
IWorkbenchPage.VIEW_VISIBLE). (My view does not allow multiple instances.)

There does not seem to be a method in IViewPart that would be relevant.

Have I missed something, or is this an oversight by Eclipse, or just a bug?

thanks,
Paul

I'm surprised that showView(id) doesn't activate the view.

showView(id) calls showView(id, null, VIEW_ACTIVATE) which looks up the
viewpart and then calls IWorkbenchPage#activate(part).

If you can put together a usecase where this isn't working, please open
a bug at https://bugs.eclipse.org/bugs/

Doh on me: I was first calling findView(ID), and *only* calling showView(ID) if the findView()
returned null -- i.e., I had misunderstood the intent of the two methods, thinking that a null
return from findView() meant that the View needed to be opened or made visible, whereas a null
return seems to mean only that the ID is bad (or something like that). If I simply always call
showView(ID), the view is indeed brought to the front.

thanks, sorry for extra trouble,
Paul

Actually, findView(*) will return the IViewPart if the view is currently
open (visible or not).

showView(*) for all intents and purposes does a findView(*), and if the
view is in the page does an activate(part) ... if the findView(*)
returned null, then it actually tries to create the view.
