How to add class member function in QScriptEngine

Sacha_D

I need to add class member function in QScriptEngine.
How to do this correctly?

.h file
@class MainWindow : public QMainWindow
{
Q_OBJECT
private:
QScriptEngine scriptEngine;

  void setupFirst();

public:
QScriptValue appendDevice(QScriptContext *ctx, QScriptEngine *eng);
};@

.cpp file
@void MainWindow::setupFirst() {

this->scriptEngine.globalObject().setProperty("appendDevice",
this->scriptEngine.newFunction(
boost::bind(&MainWindow::appendDevice, this, _1, _2),
3)
); // How to do this correctly?
}

QScriptValue MainWindow::appendDevice(QScriptContext *ctx, QScriptEngine *eng){

QString functionDescription = tr("Function format ") + "bool appendDevice(QString name, int address, const QString portName," +
        "const int rate = 115200," +
        "const QString config = \"\");";
if (ctx->argumentCount() < 3){
    return ctx->throwError(QScriptContext::SyntaxError, tr("Unsufficient args count. ") + functionDescription);
}
QString name;
int address;
QString portName;
if (ctx->argumentCount() >= 3){
    if (ctx->argument(0).isString()) {
        name = ctx->argument(0).toString();
    }
    else {
        return ctx->throwError(QScriptContext::TypeError, tr("Arg [0] (Device name) must be a string. ") + functionDescription);
    }

    if (ctx->argument(1).isNumber()) {
        address = ctx->argument(1).toInt32();
    }
    else {
        throw ctx->throwError(QScriptContext::TypeError, tr("Arg [1] (Device address) must be a number. ") + functionDescription);
    }

    if (ctx->argument(2).isString()) {
        portName = ctx->argument(2).toString();
    }
    else {
        throw ctx->throwError(QScriptContext::TypeError, tr("Arg [2] (Device port) must be a string. ") + functionDescription);
    }
}
int rate  = QExtSerialPortAux::rateToInt(QExtSerialPortAux::defaultRate);
QString config;

if (ctx->argumentCount() >= 4){
    if (ctx->argument(3).isNumber()) {
        rate = ctx->argument(3).toInt32();
    }
    else {
        throw ctx->throwError(QScriptContext::TypeError, tr("Arg [3] (Port baud rate) must be a number. ") + functionDescription);
    }
}
if (ctx->argumentCount() >= 5){
    if (ctx->argument(4).isString()) {
        config = ctx->argument(4).toString();
    }
    else {
        throw ctx->throwError(QScriptContext::TypeError, tr("Arg [4] (Device config) must be a string. ") + functionDescription);
    }
}

return appendDeviceFromScript(name, address, portName, rate, config);

}

Thank you for your replies.

MainWindow::appendDevice should be static function, then you can do what.
