Interface Summary

Interface	Description
ConstraintsProperty	The ConstraintsProperty is a marker interface intended to identify the pseudo property for "constraints".
ConstraintsPropertyState	The ConstraintsPropertyState interface is intended to act as the CmtPropertyState associated with a ConstraintsProperty.
InnerAssistant	The InnerAssistant interface is a marker interface intended to indicate that a given LayoutAssistant implementation represents a LayoutManager which is Container specific.
LayoutAssistant	A LayoutAssistant is a design time only object representing a LayoutManager and is used by the UICanvas to simplify UI design operations.
LayoutConstants	Command Id's for common LayoutAssistant actions.
SelectionEffects	SelectionEffects encapsulates the handling of SelectNib instances upon an associated UICanvas.
UIModel	UIModel is simply a marker interface extending CmtModel for the purpose of fetching from the UIManager the ModelFactory implementation that is responsible for producing the UICanvas implementation.

Class Summary

Class	Description
AbstractAssistant	AbstractAssistant provides a base implementation for LayoutAssistant.
AssistantExplorer
BoxEffects	BoxEffects encapsulates the facilities for drawing boxes upon an associated UICanvas instance.
SelectNib	SelectNib encapsulates the facilities for manipulating selection handles of an associated target displayed upon a UICanvas instance.
UICanvas	UICanvas represents a design canvas to be hosted by the UIEditor when manipulating GUI objects.

Package oracle.jdeveloper.uieditor.uicanvas Description

Contains classes that allow addins access to the UICanvas integration objects.

The UICanvas subsystem represents a UIEditorCanvas that deals only with non menu GUI objects of a java source file, and any java.awt.LayoutManager objects associated with those GUI objects. This canvas (see UICanvas) employs assistants (see LayoutAssistant) to handle the user interaction with the GUI model being depicted. Each type of layout manager must be represented by an assistant such that the assistant may interpret the user gestures within the context of the layout manager that it represents. Integrators may enable UICanvas interaction with foriegn layout managers by registering assistant implementations for those layout managers.
