  • index
    Type: System.UInt32
    [in] Specifies the index of the list item of interest.
  • ListTypeExcluded
    Type: System.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
    Type: System.Int32%
    [out] Pointer to a flag indicating expandability.

Return Value

Type: System.Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.


COM Signature

From vsshell80.idl:

HRESULT IVsObjectList2::GetExpandable3(
   [in] ULONG Index, 
   [in] LIB_LISTTYPE2 ListTypeExcluded, 
   [out] BOOL *pfExpandable

The environment's object manager calls 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 a value from the _LIB_LISTTYPE enumeration 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 GetCategoryField2 instead of GetExpandable3, return E_NOTIMPL from GetExpandable3. The environment then calls GetCategoryField2 to obtain expandability information.
