)

Parameters

index: Type: System::UInt32
[in] Specifies the index of the child node of the current tree list to be expanded.

pfCanRecurse: Type: System::Int32
[out] Pointer to a flag indicating that the tree list can recurse.

Remarks

COM Signature

From vsshell.idl:

C++

HRESULT IVsLiteTreeList::GetExpandedList(
   [in] ULONG Index,
   [out] BOOL *pfCanRecurse,
   [out] IVsLiteTreeList **pptlNode
);

On successful return, the tree list node will be expanded in the object browser window, showing all child nodes. This is one of two available mechanisms for expanding a list. The preferred mechanism is GetCategoryField.
