    Default Scripting in Qt

    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:

    Qt Code:
    1. function drawCircle()
    2. {
    3. center(10, 10);
    4. radius(10);
    5. }
    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:

    Qt Code:
    1. QJSValue function = jsEngine->evaluate("function drawCircle() {center(x, y); radius(r);}");
    2. QJSValueList args;
    3. args << 1;
    4. QJSValue result = function.call(args);
    5. int rslt = result.toInt();
    6. 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.

    In general yes, but you might want to look at QScriptEngine instead.
    Theoretically QJSEngine was intended to be its replacement but its non-QML development has been suspended for now.

    Okay. So I should use QScriptEngine. Can you point me out to some examples having form as I need?

    There is a bunch of examples on QtScript bundled with Qt.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.
