This method adds an item to the end of the IXRPathFigureCollection collection and retrieves the index that indicates where it was added.

Syntax

virtual HRESULT STDMETHODCALLTYPE Add(
    __in IXRPathFigure* pObject,
    __out_opt int* pIndex
) = 0;

Parameters

pObject
[in] Pointer to an IXRPathFigure object that represents an item to add to this collection.

pIndex
[out] Optional. Pointer to an integer value that indicates the zero-based index that describes the location of the item added to this collection.

Return Value
