The QScriptProgram class encapsulates a Qt Script program. 更多...
头: | #include <QScriptProgram> |
qmake: | QT += script |
Since: | Qt 4.7 |
该类在 Qt 4.7 引入。
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 |
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);
