QXmlAttributes ¶

概要 ¶

详细描述 ¶

If attributes are reported by startElement() this class is used to pass the attribute values.

使用 index() to locate the position of an attribute in the list, count() to retrieve the number of attributes, and clear() to remove the attributes. New attributes can be added with append() 。使用 type() to get an attribute’s type and value() to get its value. The attribute’s name is available from localName() or qName() , and its namespace URI from uri() .
