+ \class QDeclarativeError
+ \since 4.7
+ \brief The QDeclarativeError class encapsulates a QML error.
+
+ QDeclarativeError includes a textual description of the error, as well
+ as location information (the file, line, and column). The toString()
+ method creates a single-line, human-readable string containing all of
+ this information, for example:
+ \code
+ file:///home/user/test.qml:7:8: Invalid property assignment: double expected
+ \endcode
+
+ You can use qDebug() or qWarning() to output errors to the console. This method
+ will attempt to open the file indicated by the error
+ and include additional contextual information.
+ \code
+ file:///home/user/test.qml:7:8: Invalid property assignment: double expected
+ y: "hello"
+ ^
+ \endcode
