| XmlHandler (Image *image, FileName imageFolder) |
| Create an XML Handler (reader) that can populate the Image class data.
|
|
virtual bool | startElement (const QString &namespaceURI, const QString &localName, const QString &qName, const QXmlAttributes &atts) |
| Read mage class attributes.
|
|
virtual bool | characters (const QString &ch) |
| This implementation of a virtual function calls QXmlDefaultHandler::characters(QString &ch) which in turn calls QXmlContentHandler::characters(QString &ch) which is called when the XML processor has parsed a chunk of character data.
|
|
virtual bool | endElement (const QString &namespaceURI, const QString &localName, const QString &qName) |
| The XML reader invokes this method at the end of every element in the XML document.
|
|
virtual void | setReader (XmlStackedHandlerReader *) |
|
void | switchToNewHandler (XmlStackedHandler *nextHandler) |
| Switch to a new content handler and continue processing using the new handler.

Process XML in a stack-oriented fashion.
Child class for XmlStackedHandler which is used to process XML in a stack-oriented way. It's been modified to process an Image object object.

The XML reader invokes this method at the end of every element in the XML document.
This expects <image> and <footprint> elements.
- Parameters
-
namespaceURI | The Uniform Resource Identifier of the namespace (eg. "xmlns") |
localName | The local name string (eg. "xhtml") |
qName | The XML qualified string (eg. "xmlns:xhtml"). This can be empty if QNames are not available. |
- Returns
- bool If this function returns True, then a signal is sent to the reader indicating the end of the element. If this function returns False, something bad happened and processing stops.

Read mage class attributes.
The XML reader invokes this method at the start of every element in the XML document. This expects <image> and <displayProperties> elements. A quick example using this function: startElement("xsl","stylesheet","xsl:stylesheet",attributes)
- Parameters
-
namespaceURI | The Uniform Resource Identifier of the element's namespace |
localName | The local name string |
qName | The XML qualified string (or empty, if QNames are not available). |
atts | The XML attributes attached to each element |
- Returns
- bool Returns True signalling to the reader the start of a valid XML element. If False is returned, something bad happened.
