Inherits From:
TLinkedGrafState
Inherited By:
None.
Purpose:
Derived from TLinkedGrafState, TLinkedClipGrafState links a TGArea object (or a TLinkableClipState, or TLinkableTransformedClipState object) to a parent TGrafState object. This class is used internally by TLinkedClipPort. Most programmers who want to link a clip area or clip state into a graphics hierarchy use TLinkedClipPort, instead of using TLinkedClipGrafState directly.
Instantiation:
Allocate on the heap or the stack.
Deriving Classes:
None.
Concurrency:
Not multithread safe.
Resource Use:
No special requirements.
- TLinkedClipGrafState (const TGrafState * parent, const TGArea & clipArea)
- TLinkedClipGrafState (const TGrafState * parent, TLinkableTransformedClipState * clipState)
- TLinkedClipGrafState (const TGrafState * parent, TLinkableClipState * clipState)
Interface Category:
API.
Purpose:
- Constructor that links the specified clip area to the specified parent graphics state. A local clip state is instantiated and linked to the parent graphics state.
- Constructor that links the specified transformed clip state to the specified parent graphics state.
- Constructor that links the specified clip state to the specified parent graphics state.

virtual const TClipState * GetClipState () const
Interface Category:
API.
Purpose:
Returns a constant pointer to the clip state previously linked to the parent.
Calling Context:
Call this function directly.
Parameters:
Return Value:
Returns a constant pointer to the clip state.
Exceptions:
Throws no exceptions, passes all exceptions through.
Concurrency:
Not multithread safe.
Other Considerations:
None.
