Detailed Description

The QQmlError class encapsulates a QML error.

Since: 5.0 \inmodule QtQml

QQmlError 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:

file

QFile * file

Definition src_network_access_qhttpmultipart.cpp:14

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.

file:
        y: "hello"
           ^

Member Function Documentation

◆ column()

int QQmlError::column ( ) const

Returns the error column number.

Definition at line 178 of file qqmlerror.cpp.

◆ description()

QString QQmlError::description ( ) const

Returns the error description.

Definition at line 138 of file qqmlerror.cpp.

◆ isValid()

bool QQmlError::isValid ( ) const

Returns true if this error is valid, otherwise false.

Definition at line 110 of file qqmlerror.cpp.

◆ line()

int QQmlError::line ( ) const

Returns the error line number.

Definition at line 158 of file qqmlerror.cpp.

◆ messageType()

QtMsgType QQmlError::messageType ( ) const

Since: 5.9

Returns the message type.

Definition at line 223 of file qqmlerror.cpp.

◆ object()

QObject * QQmlError::object ( ) const

Returns the nearest object where this error occurred.

Exceptions in bound property expressions set this to the object to which the property belongs. It will be 0 for all other exceptions.

Definition at line 201 of file qqmlerror.cpp.

◆ operator=()

QQmlError & QQmlError::operator= ( const QQmlError & other )

Assigns other to this error object.

Definition at line 81 of file qqmlerror.cpp.

◆ setColumn()

void QQmlError::setColumn ( int column )

Sets the error column number.

Definition at line 188 of file qqmlerror.cpp.

◆ setDescription()

void QQmlError::setDescription ( const QString & description )

Sets the error description.

Definition at line 148 of file qqmlerror.cpp.

◆ setLine()

void QQmlError::setLine ( int line )

Sets the error line number.

Definition at line 168 of file qqmlerror.cpp.

◆ setMessageType()

void QQmlError::setMessageType ( QtMsgType messageType )

Since: 5.9

Sets the messageType for this message. The message type determines which QDebug handlers are responsible for receiving the message.

Definition at line 236 of file qqmlerror.cpp.

◆ setObject()

void QQmlError::setObject ( QObject * object )

Sets the nearest object where this error occurred.

Definition at line 211 of file qqmlerror.cpp.
