Retrieves the value of the specified text attribute across the entire text range.
Type: TEXTATTRIBUTEID
The identifier of the text attribute. For a list of text attribute IDs, see Text Attribute Identifiers.
Type: VARIANT*
Receives the value of the specified attribute.
Type: HRESULT
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
The type of value retrieved by this method depends on the attr parameter. For example, calling GetAttributeValue with the attr parameter set to UIA_FontNameAttributeId returns a string that represents the font name of the text range, while calling GetAttributeValue with attr set to UIA_IsItalicAttributeId would return a boolean.
If the attribute specified by attr is not supported, the value parameter receives a value that is equivalent to the IUIAutomation::ReservedNotSupportedValue property.
A text range can include more than one value for a particular attribute. For example, if a text range includes more than one font, the FontName attribute will have multiple values. An attribute with more than one value is called a mixed attribute. You can determine if a particular attribute is a mixed attribute by comparing the value retrieved from GetAttributeValue with the UIAutomation::ReservedMixedAttributeValue property.
The GetAttributeValue method retrieves the attribute value regardless of whether the text is hidden or visible. Use UIA_ IsHiddenAttributeId to check text visibility.
