  • Method Details

    • dispose

      public void dispose()
      Description copied from interface: IWorkbenchWindowActionDelegate
      Disposes this action delegate. The implementor should unhook any references to itself so that garbage collection can occur.
      Specified by:
      dispose in interface IWorkbenchWindowActionDelegate

    • init

      public void init(IWorkbenchWindow window)
      Description copied from interface: IWorkbenchWindowActionDelegate
      Initializes this action delegate with the workbench window it will work in.
      Specified by:
      init in interface IWorkbenchWindowActionDelegate
      Parameters:
      window - the window that provides the context for this delegate

    • run

      public void run(IAction action)
      Description copied from interface: IActionDelegate
      Performs this action.

      This method is called by the proxy action when the action has been triggered. Implement this method to do the actual work.

      Note: If the action delegate also implements IActionDelegate2, then this method is not invoked but instead the runWithEvent(IAction, Event) method is called.

      Specified by:
      run in interface IActionDelegate
      Parameters:
      action - the action proxy that handles the presentation portion of the action

    • selectionChanged

      public void selectionChanged(IAction action, ISelection selection)
      Description copied from interface: IActionDelegate
      Notifies this action delegate that the selection in the workbench has changed.

      Implementers can use this opportunity to change the availability of the action or to modify other presentation properties.

      When the selection changes, the action enablement state is updated based on the criteria specified in the plugin.xml file. Then the delegate is notified of the selection change regardless of whether the enablement criteria in the plugin.xml file is met.

      Specified by:
      selectionChanged in interface IActionDelegate
      Parameters:
      action - the action proxy that handles presentation portion of the action
      selection - the current selection, or null if there is no selection.
