Scripting in Qt

[Kamalpreet]

I have a widgets application. I am trying to implement scripting in this application.

The user will create a script using javascript which will be executed on pressing a QPushButton.

The script is expected to be of the form:

function drawCircle() 
{
    center(10, 10);
    radius(10);
}

function drawCircle() 
{
    center(10, 10);
    radius(10);
}

To copy to clipboard, switch view to plain text mode 

I am trying to use QJSEngine class. How the evaluation of script is to be done?

I have tried the following code snippet in the application:

QJSValue function = jsEngine->evaluate("function drawCircle() {center(x, y); radius(r);}");
QJSValueList args;
args << 1;
QJSValue result = function.call(args);
int rslt = result.toInt();
qDebug() << rslt;

QJSValue function = jsEngine->evaluate("function drawCircle() {center(x, y); radius(r);}");
QJSValueList args;
args << 1;
QJSValue result = function.call(args);
int rslt = result.toInt();
qDebug() << rslt;

To copy to clipboard, switch view to plain text mode 

Is this the right way to add scripting to the application? Please enlighten me on this.
