Method Detail

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

run

public void run()

Description copied from class: Action

The default implementation of this IAction method does nothing. Subclasses should override this method if they do not need information from the triggering event, or override runWithEvent(Event) if they do.

Specified by:: run in interface IAction
Overrides:: run in class 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.
