Re: [platform-ui-dev] dynamic content in pop-up menus for objectContribution
|
Chris,
Correct, object contributions do not support dynamic items. The main
issue is that we want to avoid plugin activation.
We've considered scenarios like:
- allow a dynamic menu to be declared in the XML
- allow it to be placed in existing menus (either in specific main menus
or context menus, or as an object contribution in context menus)
- provide programmatic API to add/remove items to a dynamic menu
- have the workbench be responsible for persisting these
- on restart, the workbench can populate the dynamic menus based on the
persisted items without activating plugins
This approach will work for dynamic submenus like Run History where the
list of items would only be updated by running code, but not for ones that
are essentially generated from other extensions in the XML (e.g. Run As).
For more context on this problem, see:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=29709
and the other PRs it references, particularly:

Re: [platform-ui-dev] dynamic content in pop-up menus for
objectContribution
Nick, thanks for your note. Just to be sure I'm not missing the point,
are you saying there is no way to add dynamic content (code or xml) in
the context of an objectContribution rather than a toolbar or view?
I looked at the OpenWithMenu and I see other examples that add "drop
down" style menus, but they all stem from toolbars or views. If there is
a mechanism, even with code, that I can build a "drop down" menu from an
object context, please hit me over the head with it.
Justification: we are trying to implement the contextual launch in such
a way as to minimize the need for further extension point contributions
(since most of the data is already specified for launch shortcuts). We
want it to be as general as possible so that it works in all reasonable
views and perhaps editors.
Thanks, Chris
