| How to assign help context id to HelpView? [message #742415] |

In our RCP program we use the Eclipse "Help View" to present the
context-sensitive help. But in contrast to other views this view seems
not to assign a help context id to its own view (Typically done via
PlatformUI.getWorkbench().getHelpSystem().setHelp()).
Does there exist a way to assign a user-defined help context id to this
view in a non-intrisive way (I don't want to modify the source code or
bundle that provides this view)?
I can think of a possible way to realize that (untested), but would
prefer a simpler version, if possible: One could add a workbench part
listener and could listen to the activation of the Help View. When this
happens one could call setHelp to the control of this view.
Is someone aware whether the adapter pattern or any similar extension
mechanism can be used to realize this?
Thanks in advance and Greetings from Bremen,

It is quite probable, that this approach wouldn't work, because
effectively the HelpView does use exactly the same strategy.

It seems that providing an IContextProvider via the adapter manager
resolves this issue. Alas, I still think that it would make sense that
the help view would also register a help context for it's view.
