-    \class QmlError
-    \since 5.0
-    \inmodule QtQml
-    \brief The QmlError class encapsulates a QML error.
-
-    QmlError 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(), qInfo(), 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
-
-    Note that the \l {Qt Quick 1} version is named QDeclarativeError
-
