Hi i want make CustomContextMenu in reimplement QTreeView , but i have done somting wrong ;(

.h
Qt Code: 
  1. #ifndef MYTREEVIEW_H
  2. #define MYTREEVIEW_H
  3.  
  4. #include <QtGui>
  5. #include <QtCore>
  6.  
  7. class MyTreeView : public QTreeView
  8. {
  9.     Q_OBJECT
  10. public:
  11.     explicit MyTreeView(QWidget *parent = 0);
  12.  
  13. signals:
  14.  
  15. public slots:
  16.     void slotCustomContextMenu(QPoint &point);
  17.     void slotTest();
  18.  
  19. };
  20.  
  21. #endif // MYTREEVIEW_H
To copy to clipboard, switch view to plain text mode 

.cpp
Qt Code: 
  1. #include "mytreeview.h"
  2.  
  3. MyTreeView::MyTreeView(QWidget *parent) :
  4.     QTreeView(parent)
  5. {
  6.     this->setContextMenuPolicy(Qt::CustomContextMenu);
  7.     connect(this,SIGNAL(customContextMenuRequested(QPoint &point)), this, SLOT(slotCustomContextMenu(QPoint &point)));
  8. }

  10. void MyTreeView::slotCustomContextMenu(QPoint &point)
  11. {
  12.      QMenu *menu = new QMenu;
  13.      QModelIndex index = this->currentIndex();
  14.  
  15.      QString fileName = this->model()->data(this->model()->index(index.row(), 0),0).toString();
  16.      menu->addAction(QString("Import"), this, SLOT(slotTest()));
  17.      menu->addAction(QString("Export"), this, SLOT(slotTest()));
  18.      menu->exec(QCursor::pos(&#41;);
  19. }
