Call object method using qtscript

[mvbhavsar]

Hi,

I want to use QtScript in one of my application. for this I have created following class.


datefunction.h

#ifndef DATEFUNCTION_H
#define DATEFUNCTION_H
 
#include <QtCore>
 
class DateFunction : public QObject
{
    Q_OBJECT
 
public:
    explicit DateFunction(QObject *parent = 0);
 
signals:
 
public slots:
    int daysInYear(QString year);
};
 
#endif // DATEFUNCTION_H

#ifndef DATEFUNCTION_H
#define DATEFUNCTION_H

#include <QtCore>

class DateFunction : public QObject
{
    Q_OBJECT

public:
    explicit DateFunction(QObject *parent = 0);
    
signals:

public slots:
    int daysInYear(QString year);
};

#endif // DATEFUNCTION_H

To copy to clipboard, switch view to plain text mode 

datefunction.cpp

#include "datefunction.h"
 
DateFunction::DateFunction(QObject *parent) :
    QObject(parent)
{
}
 
int DateFunction::daysInYear(QString year)
{
    int str=0;
    QDate d1 = QDate::fromString(year,"yyyy");
    if (!d1.isValid())
        return str;
    str = d1.daysInYear();
    return str;
}

#include "datefunction.h"

DateFunction::DateFunction(QObject *parent) :
    QObject(parent)
{
}

int DateFunction::daysInYear(QString year)
{
    int str=0;
    QDate d1 = QDate::fromString(year,"yyyy");
    if (!d1.isValid())
        return str;
    str = d1.daysInYear();
    return str;
}

To copy to clipboard, switch view to plain text mode 

Now I want user to use this in qtscript and user should be able to call daysInYear() method in QScriptEngine.evaluate() function by passing this method and required parameter as a string.
Can anybody help me on this.

What have you tried so far?

[mvbhavsar]

I have come up upto here only

#include <QtCore>
#include "datefunction.h"
#include <QtScript>
 
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    QScriptEngine eng;
    QObject *obj = new DateFunction;
    QScriptValue val = eng.newQObject(obj,QScriptEngine::ScriptOwnership);
 
    return a.exec();
}

#include <QtCore>
#include "datefunction.h"
#include <QtScript>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    QScriptEngine eng;
    QObject *obj = new DateFunction;
    QScriptValue val = eng.newQObject(obj,QScriptEngine::ScriptOwnership);
   
    return a.exec();
}

To copy to clipboard, switch view to plain text mode 

Not sure how to use val variable to get class function call

Fetch the global object and set val as a property of that object. Then you can use this property to access your function.

Additionally, have a look at registering a stand-alone function
