Examples of org.eclipse.jface.action.IAction

org.eclipse.jface.action.IAction
An action represents the non-UI side of a command which can be triggered by the end user. Actions are typically associated with buttons, menu items, and items in tool bars. The controls for a command are built by some container, which furnished the context where these controls appear and configures them with data from properties declared by the action. When the end user triggers the command via its control, the action's run method is invoked to do the real work.
Actions support a predefined set of properties (and possibly others as well). Clients of an action may register property change listeners so that they get notified whenever the value of a property changes.

Clients should subclass the abstract base class Action to define concrete actions rather than implementing IAction from scratch.

This interface exists only to define the API for actions. It is not intended to be implemented by clients.
