IXRHitTestResults::GetItem (Compact 2013)
3/28/2014
This method retrieves the item at the specified index in this hit-test results object.
Syntax
virtual HRESULT STDMETHODCALLTYPE GetItem(
int ItemIndex,
IXRDependencyObject** ppItem
) = 0;
Parameters
- ItemIndex
[in] Integer value that specifies the index location of the affected object for which you want to retrieve an object pointer.
- ppItem
[out] Address of a pointer to an IXRDependencyObject at the specified indexed location. It represents a UI element that was affected by the hit test.
Return Value
Returns an HRESULT that indicates success or failure.
Remarks
A hit-test results object contains an ordered list of objects that were affected by a hit test.
You can calculate the number of indexed items in the list by retrieving the item count from the method IXRHitTestResults::GetCount.
To use a specific interface pointer type, you can 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
None.
