- All Implemented Interfaces:
- IContributionItem, IWorkbenchContribution
public class KSBasEContributionItem
- extends CompoundContributionItem
- implements IWorkbenchContribution
Dynamic toolbar contribution for the use with KIELER View Management. It extends the idea of
CompoundContributionItems, which are only defined for menus, to toolbars. Hence, the toolbar is
filled dynamically with buttons, which only get updated at the ToolbarManager updates, which are
not in control of the user. Hence, newly inserted buttons or visibility updates might be delayed
until the next ToolbarManager update, which is for example at a change to a different kind of
editor or the change of the perspective.
All visibility management is implemented using the standard core expressions of eclipse that are
also used by the org.eclipse.ui.menu extension point. However, the core expressions API is not
publicly available due to restrictions in the corresponding org.eclipse.core.expressions plug-in
and therefore result in compiler warnings.
