window
- the window that provides the context for this delegatepublic void run(IAction 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.

action
- the action proxy that handles the presentation portion of the
actionpublic void selectionChanged(IAction action, ISelection selection)
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.
