Bug 49751 [Contributions] IWorkbenchActionConstants inconsistency
IWorkbenchActionConstants has M_VIEW but not M_PERSPECTIVE. The M_VIEW comment references the Perspective menu. Also it has M_WORKBENCH which I don't think is used any more. /** * Name of standard Perspective menu (value <code>"view"</code>). */ public static final String M_VIEW = MENU_PREFIX+"view"; //$NON-NLS-1$ /** * Name of standard Workbench menu (value <code>"workbench"</code>). */ public static final String M_WORKBENCH = MENU_PREFIX+"workbench"; // $NON-NLS-1$
