Hi everyone,

I have a problem connecting a signal to a slot.
I'm making a chessgame using QGraphicsView and an array of DnDPixmaps:


Qt Code: 
  1. #ifndef DNDPIXMAP_H
  2. #define DNDPIXMAP_H
  3.  
  4. #include <QPixmap>
  5. #include <QObject>
  6. #include <QGraphicsPixmapItem>
  7. #include <QGraphicsSceneDragDropEvent>
  8. class uitzicht;
  9. class DnDPixmap:public QObject, public QGraphicsPixmapItem
  10. {
  11.     Q_OBJECT
  12.     // No Q_OBJECT macro, as QGraphicsPixmapItem is not derived from QObject!
  13.  
  14.  
  15. public:
  16.     // Constructor gets a QPixmap which it will display.
  17.     DnDPixmap(const QPixmap &pixmap, uitzicht* a);
  18.     int oudeX;
  19.     int oudeY;
  20. protected:
  21.     // Overloaded methods to enable dragging.
  22.     virtual void mousePressEvent(QGraphicsSceneMouseEvent* event);
  23.     virtual void mouseMoveEvent(QGraphicsSceneMouseEvent* event);
  24.     // Overloaded methods for dropping.
  25.     virtual void dragEnterEvent(QGraphicsSceneDragDropEvent *event);
  26.     virtual void dropEvent(QGraphicsSceneDragDropEvent *event);
  27.  
  28. signals:
  29.     void moveMade( int x,  int y,  int oudeX,  int oudeY);
  30.  
  31. private:
  32.     // This member holds the copied QPixmap resulting from a drop.
  33.     QPixmap pix;
  34. };
  35.  
  36. #endif // DNDPIXMAP_H

  11. DnDPixmap::DnDPixmap(const QPixmap &pixmap, uitzicht* a)
  13. {
  14.  
  15.     // Make sure we allow drops.
  16.     setAcceptDrops(true);
  17.     connect(this, SIGNAL(moveMade(  int,   int,   int,   int)), a, SLOT(myslot( int,   int,   int,   int)));
  18.  
  19. }
  20.  
  21. //more stuffs

my view:

  2. #include "Spelbord.h"
  3. #include <QGraphicsView>
  4. #include <QGraphicsScene>
  5. #include "dndpixmap.h"
  6.  
  7.  
  8. void uitzicht::myslot(const int x, const int y, const int oudeX, const int oudeY){
  9.     //see if the move is possible
  10.     //Schaakstuk* a = bord->geefSchaakStuk(oudeX, oudeY);
  11.  
  12.  
  13.     //if yes update the model by changing the table
  14.     bord->verplaatsSchaakStuk(oudeX, oudeY, x, y);
  15.  
  16.     //update the view, if needed
  17.     this->print();
  18. }

  24.     bool witAanZet;
  26. };
  27.  
  28. #endif // UITZICHT_H

In the constructor of DnDPixmap, I want to connect the signal 'moveMade' to the slot of the view 'mySlot', but I get this error:
dndpixmap.cpp:17: error: no matching function for call to 'DnDPixmap::connect(DnDPixmap* const, const char*, uitzicht*&, const char*)'

I already derived DnDPixmap from QObject as I learned from another thread outhere, though it's still not working

Can someone help me with this please?
Thanks in advance!
