TQAGetNoticeMethod

A drawing engine must define a method to return the notice method of a draw context.

typedef TQAError (*TQAGetNoticeMethod) ( 
                                        const TQADrawContext *drawContext, 
                                        TQAMethodSelector method, 
                                        TQANoticeMethod *completionCallBack, 
                                        void **refCon);

drawContext

A draw context.

method

A method selector. See "Notice Method Selectors" (page 1-68) for a description of the available method selectors.

completionCallBack

On exit, a pointer to the current draw context notice method of the specified type.

refCon

On exit, the reference constant of the specified notice method.

DESCRIPTION

Your TQAGetNoticeMethod function should return, in the completionCallBack parameter, a pointer to the current notice method of the draw context specified by the drawContext parameter that has the type specified by the method parameter. TQAGetNoticeMethod should also return, in the refCon parameter, the reference constant associated with that notice method.
