Parameters

index
Type: System.UInt32

[in] Specifies the index of the list item of interest.

ListType
Type: System.UInt32

[in] Specifies the type of list being requested. Values are taken from the _LIB_LISTTYPE enumeration.

flags
Type: System.UInt32

[in] Specifies the flags that control the request for object list information. Values are taken from the _LIB_LISTFLAGS enumeration.

pobSrch
Type: array<Microsoft.VisualStudio.Shell.Interop.VSOBSEARCHCRITERIA2[]

[in] Unused. Should be ignored.

ppIVsObjectList2
Type: Microsoft.VisualStudio.Shell.Interop.IVsObjectList2%

[out] Pointer to the IVsObjectList2 interface of the returned child list.

Return Value

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

Remarks

COM Signature

From vsshell80.idl:

HRESULT IVsObjectList2::GetList2(
   [in] ULONG Index, 
   [in] LIB_LISTTYPE2 ListType, 
   [in] LIB_LISTFLAGS Flags, 
   [in] VSOBSEARCHCRITERIA2 *pobSrch, 
   [out, retval] IVsObjectList2 **ppIVsObjectList2
);

When the user expands a list node, the object manager asks the list what child lists it supports under that list item by calling GetCategoryField2 (index, LC_LISTTYPE). Then it calls IVsObjectList2::GetList with each of the list types returned as supported.

Under an LC_PHYSICALCONTAINERS list a library would typically support LLT_NAMESPACES, LLT_CLASSES, and LLT_MEMBERS lists. Under LLT_NAMESPACES list, support LLT_NAMESPACES (for nested namespaces), and LLT_MEMBERS. Under LLT_CLASSES list, support LLT_CLASSES (for nested classes), and LLT_MEMBERS lists. LLT_HIERARCHY lists can appear anywhere to provide auxiliary information nodes such as Bases and Interfaces nodes, a Derived Classes node, and so on.

When GetList2 is called, your library should create (or reuse existing) an IVsObjectList2 based on the specified category for the specified tool (as per the flags). Any TTO_SORTTEXT strings allocated for the items that are obtained by the object manager through subsequent calls to GetText must be kept valid until the list's final release.
