Disable the duplication of a perspective by dragging [message #447500]

Hello,

I get a problem in my RCP app because I cannot manage duplicated editors
on the same resource.
For duplicated editors, I have found that presentations extension point
could solve the problem and remove the 'New editor' action in the
context menu of the editor tab.

The problem comes now from perspectives. Indeed, the user is still able
to duplicate a perspective in a new window by dragging its icon from the
perspective toolbar.
Then, the user can open the same resource in an editor in each instance
of the duplicated perspective. Here's the point.

My question is quite simple :
How to disable the ability to duplicate a perspective in a new window ?

Thanks in advance.

Nobody ? I really need help on this point. If I were not clear, I could
better describe my problem.

Your problem as stated, you cannot disable this duplication of
perspectives, unless you remove new window and the perspective switcher
from your RCP app.

Your actual problem is you cannot have 2 editors open on your same
resource at the same time. I'd try and fix that problem.

Option 1: move to an MVC pattern, like the text editors. They take
their editor input and ask a document provider for their document. The
document provider will hand back the same document model for the same
editor input. Now both editors are working on the same model, and
property change events cause both editors to update their info at the
same time.

Option 2: Manage your list of open resources, and if a request to open
an input that's already in your list occurs don't fully open your normal
editor, just open it with a message window saying "Resource already open
.... please contact your dealer."

Later,
