Detailed Description

Encapsulates an IlvGroup into a regular IlvGraphic.

Library: ilvproto

IlvProtoGraphic is a subclass of IlvGraphic that encapsulates an IlvGroup. IlvProtoGraphic can be added to any manager or container, like any other Rogue Wave Views graphic object.

The recommended way to use the prototypes and IlvGroup features is to place an IlvGroup into an IlvProtoGraphic and use regular managers.

All calls to the changeValue, queryValue, and getAccessors methods are propagated to the internal group, so that handling an IlvProtoGraphic works exactly the same way as handling an IlvGroup.

Note

Although the IlvProtoGraphic class inherits from the IlvGraphic class, the setInteractor() function must NOT be used to change the interactor on an IlvProtoGraphic object, because IlvProtoGraphic objects each have their own internal interactor.

An IlvProtoGraphic object cannot manage the focus correctly because it is an IlvGraphic object. Only the classes that inherit from IlvGadget class can manage the focus correctly.

Constructor & Destructor Documentation

IlvProtoGraphic() [1/3]

IlvProtoGraphic::IlvProtoGraphic	(	IlvDisplay *	display,
		IlvGroup *	group,
		IlBoolean	owner = IlTrue
	)

Initializes a new prototype graphic that encapsulates a group.

Parameters

display	Display used to initialize the object.
group	Group to be encapsulated.
owner	If set to IlTrue, the group will be deleted when the object is deleted.

IlvProtoGraphic() [2/3]

IlvProtoGraphic::IlvProtoGraphic	(	IlvDisplay *	display,
		IlvPrototype *	proto,
		IlvPalette *	palette = 0
	)

Initializes a new prototype graphic that encapsulates an instance of a prototype.

Parameters

display	Display used to initialize the object.
proto	The prototype to be encapsulated.
palette	Unused parameter, left for compatibility reasons.

IlvProtoGraphic() [3/3]

IlvProtoGraphic::IlvProtoGraphic	(	IlvDisplay *	display,
		const char *	protoName,
		IlvPalette *	palette = 0
	)

Initializes a new prototype graphic that encapsulates an instance of a prototype.

The instance encapsulated by the graphic object is created by the IlvProtoGraphic constructor. The prototype instance is always owned by the IlvProtoGraphic, that is, it will be destroyed when the graphic is destroyed.

Parameters

display	Display used to initialize the object.
protoName	Name of the prototype to be instantiated as the encapsulated group.
palette	Unused parameter, left for compatibility reasons.

Member Function Documentation

getProtoGraphic()

IlvProtoInstance* IlvProtoGraphic::getProtoGraphic

(

)

Returns the prototype instance held by this object.

Returns

If the group held by this object is a prototype instance, then return the instance. Otherwise, returns 0.
