详细描述

QScriptProgram class encapsulates a Qt Script program.

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);
