详细描述

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:

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

可以使用 qDebug () 或 qWarning () 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"
            ^
