        protected boolean allowItem​(IContributionItem itemToAdd)
        Description copied from class: ContributionManager
        This method allows subclasses of ContributionManager to prevent certain items in the contributions list. ContributionManager will either block or allow an addition based on the result of this method call. This can be used to prevent duplication, for example.
        allowItem in class ContributionManager
        itemToAdd - The contribution item to be added; may be null.
        true if the addition should be allowed; false otherwise. The default implementation allows all items.

        parent - the parent control
        the cool bar control
      • dispose

        public void dispose()
        Disposes of this cool bar manager and frees all allocated SWT resources. Notifies all contribution items of the dispose. Note that this method does not clean up references between this cool bar manager and its associated contribution items. Use removeAll for that purpose.

      • refresh

        public void refresh()
        Synchronizes the visual order of the cool items in the control with this manager's internal data structures. This method should be called before requesting the order of the contribution items to ensure that the order is accurate.

        Note that update() and refresh() are converses: update() changes the visual order to match the internal structures, and refresh changes the internal structures to match the visual order.

      • resetItemOrder

        public void resetItemOrder()
        Restores the canonical order of this cool bar manager. The canonical order is the order in which the contribution items where added.
