)

abstract OnClose : 
        ptca:VSTREECLOSEACTIONS[] byref -> int

function OnClose(
    ptca : VSTREECLOSEACTIONS[]
) : int

Parameters

ptca
Type: array<Microsoft.VisualStudio.Shell.Interop.VSTREECLOSEACTIONS[]
[out] Specifies to the tree view the action to take when closing this tree list. Values are taken from the VSTREECLOSEACTIONS enumeration.

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 vsshell.idl:

HRESULT IVsLiteTreeList::OnClose(
   [out] VSTREECLOSEACTIONS *ptca
);

OnClose is called when the user collapses the tree list. Set ptca to the appropriate enumeration value from VSTREECLOSEACTIONS to indicate what action the tree view should take.
