Remarks

COM Signature

From vsshell.idl:

HRESULT IVsLiteTreeList::GetTipText(
   [in] ULONG Index,
   [in] VSTREETOOLTIPTYPE eTipType,
   [out] const WCHAR **ppszText
);

This method returns a pointer to the tip text for the list item. GetTipText is usually not implemented. If you return E_NOTIMPL or E_FAIL to a GetText call, tip text will default to TTO_DISPLAYTEXT.

Note

The text buffer is created by the IVsLiteTreeList object and the buffer must persist for the life of the IVsLiteTreeList object.

If you are implementing this interface in managed code and you need to have the string disposed of by the caller, implement the IVsCoTaskMemFreeMyStrings interface on the IVsLiteTreeList interface.

.NET Framework Security

Full trust for the immediate caller. This member cannot be used by partially trusted code. For more information, see Using Libraries from Partially Trusted Code.
