ITextStoreACP::GetTextExt method (textstor.h)

The ITextStoreACP::GetTextExt method returns the bounding box, in screen coordinates, of the text at a specified character position. The caller must have a read-only lock on the document before calling this method.

Syntax

HRESULT GetTextExt(
  TsViewCookie vcView,
  LONG         acpStart,
  LONG         acpEnd,
  RECT         *prc,
  BOOL         *pfClipped
);

Parameters

vcView

Specifies the context view.

acpStart

Specifies the starting character position of the text to get in the document.

acpEnd

Specifies the ending character position of the text to get in the document.

prc

Receives the bounding box in screen coordinates of the text at the specified character positions.

pfClipped

Receives a Boolean value that specifies if the text in the bounding box has been clipped. If this parameter is TRUE, the bounding box contains clipped text and does not include the entire requested text range. The bounding box is clipped because the requested range is not visible.

Return value

This method can return one of these values.

TS_E_NOLOCK

Remarks

If the document window is minimized, or if the specified text is not currently visible, the method returns S_OK with the prc parameter set to {0,0,0,0}.
