Inherits From:

TLinkedGrafState

Inherited By:

None.

Purpose:

Derived from TLinkedGrafState, TLinkedSceneGrafState links a scene state to a parent TGrafState object. This class is used internally by TLinkedScenePort. Most programmers who want to link a scene state into a graphics hierarchy use TLinkedScenePort, instead of using TLinkedSceneGrafState directly.

Instantiation:

Allocate on the heap or the stack.

Deriving Classes:

None.

Concurrency:

Not multithread safe.

Resource Use:

No special requirements.

Member Function: TLinkedSceneGrafState::TLinkedSceneGrafState

TLinkedSceneGrafState (const TGrafState * parent, TLinkableClippingSceneState * sceneState)
TLinkedSceneGrafState (const TGrafState * parent, TLinkableSceneState * sceneState)

Interface Category:

API.

Purpose:

Constructor that links the specified clipping scene state to the specified parent graphics state.
Constructor that links the specified scene state to the specified parent graphics state.

Calling Context:

Call this function directly.
Call this function directly.

Parameters:

const TGrafState * parent -The TGrafState to use as the parent.
TLinkableClippingSceneState * sceneState -The clipping scene state to link to the parent.
const TGrafState * parent -The TGrafState to use as the parent.
TLinkableSceneState * sceneState -The scene state to link to the parent.

Return Value:

None.

Exceptions:

Throws no exceptions, passes all exceptions through.
