[SOLVED] can't get QTableView working

[marvin]

I'm trying to get QTableView working, from this example: http://doc.qt.nokia.com/latest/model...-example-model

so i made a new project in creator, added my custom class (a copy paste from example):
mymodel.h

#ifndef MYMODEL_H
#define MYMODEL_H
 
#include <QAbstractTableModel>
 
class MyModel : public QAbstractTableModel
{
    Q_OBJECT
public:
    MyModel(QObject *parent);
    int rowCount(const QModelIndex &parent = QModelIndex()) const ;
    int columnCount(const QModelIndex &parent = QModelIndex()) const;
    QVariant data(const QModelIndex &index, int role = Qt::DisplayRole) const;
};
#endif // MYMODEL_H

#ifndef MYMODEL_H
#define MYMODEL_H

#include <QAbstractTableModel>

class MyModel : public QAbstractTableModel
{
    Q_OBJECT
public:
    MyModel(QObject *parent);
    int rowCount(const QModelIndex &parent = QModelIndex()) const ;
    int columnCount(const QModelIndex &parent = QModelIndex()) const;
    QVariant data(const QModelIndex &index, int role = Qt::DisplayRole) const;
};
#endif // MYMODEL_H

To copy to clipboard, switch view to plain text mode 

mymodel.cpp

#include "mymodel.h"
#include "QDebug"
 
 MyModel::MyModel(QObject *parent)
     :QAbstractTableModel(parent)
 {
     qDebug() << "constructor";
 }
 
 int MyModel::rowCount(const QModelIndex & /*parent*/) const
 {
    return 2;
 }
 
 int MyModel::columnCount(const QModelIndex & /*parent*/) const
 {
     return 3;
 }
 
 QVariant MyModel::data(const QModelIndex &index, int role) const
  {
      if (role == Qt::DisplayRole)
      {
         return QString("Row%1, Column%2")
                     .arg(index.row() + 1)
                     .arg(index.column() +1);
      }
      return QVariant();
  }

#include "mymodel.h"
#include "QDebug"

 MyModel::MyModel(QObject *parent)
     :QAbstractTableModel(parent)
 {
     qDebug() << "constructor";
 }

 int MyModel::rowCount(const QModelIndex & /*parent*/) const
 {
    return 2;
 }

 int MyModel::columnCount(const QModelIndex & /*parent*/) const
 {
     return 3;
 }

 QVariant MyModel::data(const QModelIndex &index, int role) const
  {
      if (role == Qt::DisplayRole)
      {
         return QString("Row%1, Column%2")
                     .arg(index.row() + 1)
                     .arg(index.column() +1);
      }
      return QVariant();
  }

To copy to clipboard, switch view to plain text mode 

and in dialog.cpp i have push button on click, where i add the model to the table:
dialog.cpp

#include "dialog.h"
#include "ui_dialog.h"
#include "mymodel.h"
 
Dialog::Dialog(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::Dialog)
{
 
    ui->setupUi(this);
}
 
Dialog::~Dialog()
{
    delete ui;
}
 
void Dialog::on_pushButton_clicked()
{
    MyModel myModel(0);
    ui->tableView->setModel( &myModel );
    ui->tableView->show();
 
 
}

#include "dialog.h"
#include "ui_dialog.h"
#include "mymodel.h"

Dialog::Dialog(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::Dialog)
{

    ui->setupUi(this);
}

Dialog::~Dialog()
{
    delete ui;
}

void Dialog::on_pushButton_clicked()
{
    MyModel myModel(0);
    ui->tableView->setModel( &myModel );
    ui->tableView->show();


}

To copy to clipboard, switch view to plain text mode 

and when i run the example and click the button, i get this, nothing in table:

i can just guess it's something basic i have missed, but i have no idea where?

Added after 1 40 minutes:

Found the solution, i created myModel locally...
