  \brief The QScriptProgram class encapsulates a Qt Script program.+
−
+
−
  \ingroup script+
−
+
−
  QScriptProgram retains the compiled representation of the script if+
−
  possible. Thus, QScriptProgram can be used to evaluate the same+
−
  script multiple times more efficiently.+
−
+
−
  \code+
−
  QScriptEngine engine;+
−
  QScriptProgram program("1 + 2");+
−
  QScriptValue result = engine.evaluate(program);+
−
  \endcode+
