TBoldHandle¶

Abstract superclass for wrapping making clases IDE-manipulatable.

Declaration¶

TBoldHandle = class(TBoldSubscribableComponent)

Hierarchy¶

TComponent
TBoldSubscribableComponent
TBoldHandle
Direct subclasses
TBoldAbstractObjectUpgraderHandle
TBoldClientHandle
TBoldListenerHandle
TBoldOLLEHandle
TBoldPersistenceHandle
TBoldServerHandle
TBoldUMLModelLink

Description¶

The Delphi/BCB/Kylix IDE allows efficent designtime manipulation of classes decending from TComponent. Subclassing TBoldHandle way for providing access from the IDE to classes that don't decend from TComponent. Since subscriptions are used extensivley in Bold THandle inherits from TBoldSubscribableComponent. A TBoldHandle is simply a component holding a reference to a handled object. Handles are used extensively in Bold to provide placeable IDE access to various parts of Bold.

Note

A somewhat confusing fact is that not all placeable nonvisual components in Bold descend from `TBoldHandle`. This is particularly true of TBoldElementHandle and its subclasses.

Properties¶

Name	Summary	Notes
HandledObject		read-only

HandledObject¶

property HandledObject: TObject;

This is the object handled by the handle. It will normally be allocated eith by the constructor of the concrete subclass, or by the overriden GetHandledObject in the case of lazy creation.

Methods¶

Name	Summary	Notes
Create	Constructor.	override
Destroy	Destructor.	override
GetHandledObject	Get method for HandledObject	protected, abstract

Create¶

constructor Create(Owner: TComponent); override;

Constructor.

Destroy¶

destructor Destroy; override; See also Ancestor Method

Destructor. The destructor will call FreePublisher early in the process.

GetHandledObject¶

function GetHandledObject: TObject; virtual; abstract;

This method is abstract virtual, and must be overridden in all subclasses.
