\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() 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 QtQuick 1 version is named QDeclarativeError
