Since: Qt 4.7

This class was introduced in Qt 4.7.

Public Functions

QScriptProgram(const QScriptProgram &other)
QScriptProgram(const QString &sourceCode, const QString fileName = QString(), int firstLineNumber = 1)
QScriptProgram()
QScriptProgram &operator=(const QScriptProgram &other)
~QScriptProgram()
QString fileName() const
int firstLineNumber() const
bool isNull() const
QString sourceCode() const
bool operator!=(const QScriptProgram &other) const
bool operator==(const QScriptProgram &other) const

Detailed Description

QScriptProgram retains the compiled representation of the script if possible. Thus, QScriptProgram can be used to evaluate the same script multiple times more efficiently.

 QScriptEngine engine;
 QScriptProgram program("1 + 2");
 QScriptValue result = engine.evaluate(program);
