ITextStoreAnchor::RequestAttrsTransitioningAtPosition method

Syntax

C++


HRESULT RequestAttrsTransitioningAtPosition(
  [in]       IAnchor   *paPos,
  [in]       ULONG     cFilterAttrs,
  [in] const TS_ATTRID *paFilterAttrs,
  [in]       DWORD     dwFlags
);

Parameters

paPos [in]

Pointer to the anchor.

cFilterAttrs [in]

Specifies the number of attributes to obtain.

paFilterAttrs [in]

Pointer to the TS_ATTRID data type that specifies the attribute to verify.

dwFlags [in]

Specifies attributes for the call to the ITextStoreAnchor::RetrieveRequestedAttrs method. If this parameter is not set, the method returns the attributes that start at the specified anchor location. Other possible values for this parameter are the following.

Value	Meaning
TS_ATTR_FIND_WANT_END	Obtains the attributes that end at the specified anchor location.
TS_ATTR_FIND_WANT_VALUE	Obtains the value of the attribute in addition to the attribute. The attribute value is put into the varValue member of the TS_ATTRVAL structure during the ITextStoreAnchor::RetrieveRequestedAttrs method call.

Return value

This method can return one of these values.

Value	Description
S_OK	The method was successful.
E_INVALIDARG	paPos is invalid.

Remarks

In the sentence, "This is italic text.", the italic attribute starts before the word italic and ends after the word text.

If the flag TS_ATTR_FIND_WANT_END is set in dwFlags, the method would return the italic attribute for the text "italic <anchor>normal", because there is an end transition at the anchor location.
