ITfEditTransactionSink::OnStartEditTransaction method (msctf.h)

Indicates the start of an edit transaction.

Syntax

HRESULT OnStartEditTransaction(
  [in] ITfContext *pic
);

Parameters

[in] pic

Pointer to the ITfContext interface involved in the transaction.

Return value

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

The TSF manager calls this method at the start of an edit transaction. A text service might delay reevaluation of the changing context of the transaction due to the multiple ITfTextEditSink::OnEndEdit notifications until after receiving the corresponding ITfEditTransactionSink::OnEndEditTransaction callback.
