This method retrieves the item at the specified index in the IXRGeometryCollection collection.

Syntax

virtual HRESULT STDMETHODCALLTYPE GetItem(
    __in int ItemIndex,
    __out IXRGeometry** ppObject
) = 0;

Parameters

ItemIndex
[in] Integer value that specifies the index of the location of the item to retrieve.

ppObject
[out] Pointer to a pointer to an IXRGeometry object that represents the item located in the collection at the index specified in ItemIndex.

Return Value

Returns an HRESULT that indicates success or failure.

Remarks

To use a specific interface pointer type, use the helper template version of this method that XAML for Windows Embedded provides. When you supply a derived type, this version automatically supplies a type-safe method that implicitly converts the returned type from a generic interface, so you do not have to explicitly call QueryInterface to convert the generic interface into the required object type.

.NET Framework Equivalent

System.Windows.PresentationFrameworkCollection(T).Item

Requirements

Header	XamlRuntime.h
sysgen	SYSGEN_XAML_RUNTIME
