QScxmlError:: QScxmlError ()

Creates a new invalid SCXML error.

QScxmlError:: QScxmlError (const QString & fileName , int line , int column , const QString & 描述 )

Creates a new valid SCXML error that contains the error message, 描述 , as well as the fileName , line ，和 column where the error occurred.

QScxmlError:: QScxmlError (const QScxmlError & other )

構造副本為 other .

QScxmlError:: ~QScxmlError ()

Destroys the SCXML error.

int QScxmlError:: column () const

Returns the column in which the error occurred.

注意： getter 函數對於特性 column .

QString QScxmlError:: description () const

Returns the error message.

注意： getter 函數對於特性 description .

QString QScxmlError:: fileName () const

Returns the name of the file in which the error occurred.

注意： getter 函數對於特性 fileName .

bool QScxmlError:: isValid () const

返迴 true if the error is valid, false otherwise. An invalid error can only be created by calling the default constructor or by assigning an invalid error.

注意： getter 函數對於特性 valid .

int QScxmlError:: line () const

Returns the line on which the error occurred.

注意： getter 函數對於特性 line .

QString QScxmlError:: toString () const

This convenience method converts an error to a string. Returns the error message formatted as: "filename:line:column: error: description"

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

賦值 other to this SCXML error and returns a reference to this SCXML error.
