## Public Functions

| QXmlLocator()
virtual | ~QXmlLocator()
virtual int | columnNumber() const = 0
virtual int | lineNumber() const = 0

## Detailed Description

The reader reports a QXmlLocator to the content handler before it starts to parse the document. This is done with the QXmlContentHandler::setDocumentLocator() function. The handler classes can now use this locator to get the position (lineNumber() and columnNumber()) that the reader has reached.
