Detailed Description

TheQDeclarativeError class encapsulates a QML error.

QDeclarativeError includes a textual description of the error, as well as location information (the file, line, and column). ThetoString() method creates a single-line, human-readable string containing all of this information, for example:

file:///home/user/test.qml:7:8: Invalid property assignment: double expected

You can useqDebug() orqWarning() to output errors to the console. This method will attempt to open the file indicated by the error and include additional contextual information.

file:///home/user/test.qml:7:8: Invalid property assignment: double expected        y:"hello"^
