Script parser[solved]

[Ruzik]

Hellow, i need to create script math parser, for example i have this string: 1+2+3, and i want to find answer with scripts, how can i do it?
I try:
@ QScriptEngine scriptEngine;
QScriptValue scriptLineEdit = scriptEngine.newQObject(lineEdit);
scriptEngine.globalObject().setProperty("lineEdit", scriptLineEdit);
scriptEngine.evaluate("var answer = lineEdit.txt;" //<---
"lineEdit.text = answer;");@
How can I make so that the line was interpreted as a command, not a string?
