Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Returns a flag indicating whether the given list item is expandable.
public:
int GetExpandable2(System::UInt32 index, System::UInt32 ListTypeExcluded, [Runtime::InteropServices::Out] int % pfExpandable);
int GetExpandable2(unsigned int index, unsigned int ListTypeExcluded, [Runtime::InteropServices::Out] int & pfExpandable);
public int GetExpandable2 (uint index, uint ListTypeExcluded, out int pfExpandable);
abstract member GetExpandable2 : uint32 * uint32 * int -> int
Public Function GetExpandable2 (index As UInteger, ListTypeExcluded As UInteger, ByRef pfExpandable As Integer) As Integer
Parameters
- index
- UInt32
[in] Specifies the index of the list item of interest.
- ListTypeExcluded
- UInt32
[in] Specifies the list types to be excluded. Values are taken from the _LIB_LISTTYPE enumeration. This is primarily to remove LLT_MEMBERS from consideration in object browser, where they are shown in a separate pane.
- pfExpandable
- Int32
[out] Pointer to a flag indicating expandability.
Returns
If the method succeeds, it returns S_OK. If it fails, it returns an error code.
Remarks
COM Signature
From vsshell.idl:
HRESULT IVsObjectList::GetExpandable2(
[in] ULONG Index,
[in] LIB_LISTTYPE ListTypeExcluded,
[out] BOOL *pfExpandable
);
The environment's object manager will call this method to determine if an object list node has child lists. The environment may also indicate a list type to exclude from the expandable check by assigning an enumerator of _LIB_LISTTYPE to the ListTypeExcluded
parameter. Use of ListTypeExcluded
results primarily from an Object Browser query where members are listed in the right pane. If you choose to implement GetCategoryField instead of GetExpandable2
, return E_NOTIMPL from GetExpandable2
. The environment will then call GetCategoryField to obtain expandability information.
