Constructor & Destructor Documentation

◆ XmlHandler()

Isis::GuiCameraDisplayProperties::XmlHandler::XmlHandler ( GuiCameraDisplayProperties * displayProperties)

Sets the GuiCameraDisplayProperties variable pointer.

Parameters
displayPropertiesThe new pointer.

References m_displayProperties.

Member Function Documentation

◆ characters()

bool Isis::GuiCameraDisplayProperties::XmlHandler::characters ( const QString & ch)
virtual

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.

See also
XmlStackedHandler, QXmlDefaultHandler,QXmlContentHandler
Parameters
chThe character data.
Returns
bool Returns True if there were no problems with the character processing. It returns False if there was a problem, and the XML reader stops.

Definition at line 269 of file GuiCameraDisplayProperties.cpp.

◆ endElement()

bool Isis::GuiCameraDisplayProperties::XmlHandler::endElement ( const QString & namespaceURI,
const QString & localName,
const QString & qName )
virtual

The XML reader invokes this method at the end of every element in the XML document.

Parameters
namespaceURIThe Uniform Resource Identifier of the namespace (eg. "xmlns")
localNameThe local name string (eg. "xhtml")
qNameThe 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.

Reimplemented from Isis::XmlStackedHandler.

◆ setReader()

void Isis::XmlStackedHandler::setReader ( XmlStackedHandlerReader * reader)
virtualinherited

Definition at line 28 of file XmlStackedHandler.cpp.

◆ startElement()

bool Isis::GuiCameraDisplayProperties::XmlHandler::startElement ( const QString & namespaceURI,
const QString & localName,
const QString & qName,
const QXmlAttributes & atts )
virtual

The XML reader invokes this method at the start of every element in the XML document.

A quick example using this function: startElement("xsl","stylesheet","xsl:stylesheet",attributes)

Parameters
namespaceURIThe Uniform Resource Identifier of the element's namespace
localNameThe local name string
qNameThe XML qualified string (or empty, if QNames are not available).
attsThe 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.

◆ switchToNewHandler()

void Isis::XmlStackedHandler::switchToNewHandler ( XmlStackedHandler * nextHandler)
inherited

Switch to a new content handler and continue processing using the new handler.
