Interface ActionContext

All Known Implementing Classes:

AbstractActionContext, AbstractFieldActionContext, ApplicationActionContext, DelegateDataActionContext, FieldActionContext, TableActionContext, TreeActionContext, ViewActionContext, WindowActionContext

public interface ActionContext

Context for the execution of an action.

This interface is central to the Doolin GUI framework. It allows almost each element of an application (mainly GUIAction instances) to know where they are running: the application, the window, the view, the data and the contextual data.
