ITextStoreACP2::GetACPFromPoint method

Converts a point in screen coordinates to an application character position.

Syntax

HRESULT GetACPFromPoint(
  [in]        TsViewCookie vcView,
  [in]  const POINT        *ptScreen,
  [in]        DWORD        dwFlags,
  [out]       LONG         *pacp
);

Parameters

vcView [in]

Specifies the context view.

ptScreen [in]

Pointer to the POINT structure with the screen coordinates of the point.

dwFlags [in]

Specifies the character position to return based upon the screen coordinates of the point relative to a character bounding box. By default, the character position returned is the character bounding box containing the screen coordinates of the point. If the point is outside a character bounding box, the method returns NULL or TF_E_INVALIDPOINT. Other bit flags for this parameter are as follows.

The bit flags can be combined.

Value	Meaning
GXFPF_ROUND_NEAREST	If the screen coordinates of the point are contained in a character bounding box, the character position returned is the bounding edge closest to the screen coordinates of the point.
GXFPF_NEAREST	If the screen coordinates of the point are not contained in a character bounding box, the closest character position is returned.

 

pacp [out]

Receives the character position that corresponds to the screen coordinates of the point.

Return value

This method can return one of these values.
