Interface IEditorActionBarContributor

All Known Implementing Classes:
BasicTextEditorActionContributor, CompareEditorContributor, EditorActionBarContributor, EditorActionBuilder.ExternalContributor, MultiPageEditorActionBarContributor, TextEditorActionContributor

public interface IEditorActionBarContributor
A editor action bar contributor defines the actions for one or more editors.

Within the workbench there may be more than one open editor of a particular type. For instance, there may be 1 or more open Java Editors. To avoid the creation of duplicate actions and action images the editor concept has been split into two. An action contributor is responsible for the creation of actions. The editor is responsible for action implementation. Furthermore, the contributor is shared by each open editor. As a result of this design there is only 1 set of actions for 1 or more open editors.

The relationship between editor and contributor is defined by the org.eclipse.ui.editors extension point in the plugin registry.

This interface should not be implemented directly. An implementation of this interface has been created in EditorActionBarContributor. Implementors should subclass this and specialize as required.

      void init(IActionBars bars, IWorkbenchPage page)
      Initializes this contributor, which is expected to add contributions as required to the given action bars and global action handlers.

      The page is passed to support the use of RetargetAction by the contributor. In this case the init method implementors should:

      1. set retarget actions as global action handlers
      2. add the retarget actions as part listeners
      3. get the active part and if not null call partActivated on the retarget actions

      And in the dispose method the retarget actions should be removed as part listeners.

      Parameters:
      bars - the action bars
      page - the workbench page for this contributor
