VR - The visual root node of the UI toolkit this IVisualPart is
used in, e.g. javafx.scene.Node in case of JavaFX.V - The visual node used by this IVisualPart.public interface IVisualPart<VR,V extends VR> extends IAdaptable, IActivatable, IDisposable
IVisualPart plays the controller role in the model-view-controller
architecture. While it does not have to bound to a model (actually only
IContentParts are bound to model elements, IFeedbackParts and
IHandleParts do not refer to model elements), an IVisualPart
controls a visual and is responsible of handling user interaction.
Within an IViewer, IVisualPart are organized in a hierarchy
via a [1:n] parent-children relationship (getParent(),
getChildrenUnmodifiable()), which roots in an IRootPart.
Furthermore a [n:m] anchorage-anchored relationship (
getAnchoragesUnmodifiable() , getAnchoredsUnmodifiable())
may be established between IVisualParts located at arbitrary places
within the hierarchy.
An IVisualPart is adaptable (IAdaptable). Usually,
IPolicys and IBehaviors are adapted to it (but arbitrary
adapters may indeed be registered as needed). IPolicys are usually
required in case the IVisualPart is directly involved in user
interaction (e.g. the user clicks on its controlled visual). They may be
accessed type-safe by ITools or other IPolicys (
IPolicys may delegate to other IPolicys) via their class key
(see IAdaptable). IBehaviors are used to react to changes of
the attached model (in case of an IContentParts), the viewer models,
or others sources (e.g. adapters of the IViewer or IDomain),
thereby reacting to changes of the interactive state.
IVisualParts are activatable (IActivatable), and an
activation/deactivation of an IVisualPart will result in the
activation/deactivation of all registered adapters (i.e. IPolicys and
IBehaviors).
An IVisualPart is responsible for registering itself for its
visualization at the IViewer.getVisualPartMap() when it obtains a
link to the IViewer. Equally, an IVisualPart is responsible
for unregistering itself for its visualization from the
IViewer.getVisualPartMap() when it loses a link to the
IViewer.
