I am developing an Eclipse RCP application, and would like to remove some of the items displayed in the "Show In" context menu. The items are placed in this menu by various plug-ins, and I would prefer to not have them there.
Adding a new entry to this menu is well documented: https://wiki.eclipse.org/FAQ_How_do_I_make_my_view_appear_in_the_Show_In_menu%3F
However, removing an existing entry seems problematic, since Views are listed in the "Show In" menu by virtue of them implementing the IShowInTarget interface. The resulting menu items do not have unique IDs that could be used to disable them via an Activity.
It seems to me like the only way to avoid listing a View defined by an existing plug-in in the "Show In" menu is to extend the plug-in class implementing this View.
