Fix error missing ':' before identifier 'slots'

Hi,
I create new C++ class:

myxmlclass.h:

Code:

#ifndef MYXMLCLASS_H
#define MYXMLCLASS_H
 
 
class MyXMLClass
{
public:
    MyXMLClass();
 
public slots:
    void SaveXMLFile();
    void ReadXMLFile();
};
 
#endif // MYXMLCLASS_H

myxmlclass.cpp:

Code:

#include <myxmlclass.h>
#include <QFileDialog>
#include <QXmlStreamWriter>
 
void MyXMLClass::SaveXMLFile()
{
 
    QString filename = QFileDialog::getSaveFileName(this,
                                       tr("Save Xml"), ".",
                                       tr("Xml files (*.xml)"));
 
 
    QFile file(filename);
    file.open(QIODevice::WriteOnly);
 
    QXmlStreamWriter xmlWriter(&file);
    xmlWriter.setAutoFormatting(true);
    xmlWriter.writeStartDocument();
 
    xmlWriter.writeStartElement("LAMPS");
 
    xmlWriter.writeStartElement("LIGHT1");
    xmlWriter.writeTextElement("State", "statevalue" );
    xmlWriter.writeTextElement("Room", "roomvalue");
    xmlWriter.writeTextElement("Potencial", "potencialvalue");
 
    xmlWriter.writeEndElement();
 
        file.close();
}
 
 
 
void MyXMLClass::ReadXMLFile()
{
    QXmlStreamReader Rxml;
 
    QString filename = QFileDialog::getOpenFileName(this,
        tr("Open Xml"), ".",
        tr("Xml files (*.xml)"));
 
    QFile file(filename);
    if (!file.open(QFile::ReadOnly | QFile::Text))
    {
        std::cerr << "Error: Cannot read file " << qPrintable(filename)
            << ": " << qPrintable(file.errorString())

    }
 
    Rxml.setDevice(&file);

            }
            else if (Rxml.name() == "LIGHT1")
            {
                while (!Rxml.atEnd())
                {
                    if (Rxml.isEndElement())
                    {
                        Rxml.readNext();
                        break;
                    }
                    else if (Rxml.isCharacters())
                    {
                        Rxml.readNext();
                    }
                    else if (Rxml.isStartElement())
                    {
                        if (Rxml.name() == "State")
                        {

                        else if (Rxml.name() == "Room")
                        {
                            ReadRoomElement();

                }
            }
        }
        else
        {
            Rxml.readNext();
        }
 
        file.close();
 
        if (Rxml.hasError())
        {
            std::cerr << "Error: Failed to parse file "
                << qPrintable(filename) << ": "
                << qPrintable(Rxml.errorString()) << std::endl;
        }
        else if (file.error() != QFile::NoError)
        {
            std::cerr << "Error: Cannot read file " << qPrintable(filename)

                << std::endl;
        }
    }
}
 
 
 
//Example for Room Element
 
void MyXMLClass::ReadRoomElement()
{
    while(!Rxml.atEnd())
    {
        if(Rxml.isEndElement())
        {
            Rxml.readNext();
            break;
        }
        else if(Rxml.isStartElement())
        {
            QString roomelement = Rxml.readElementText();   //Get the xml value
            Rxml.readNext();
            break;
        }
        else if(Rxml.isCharacters())
        {
            Rxml.readNext();
        }
        else
        {
            Rxml.readNext();
        }
    }
 
}

I have syntax error : missing ':' before identifier 'slots'.
