Subclassing QGraphicsView

[sincnarf]

Using your previous tips I got compilation errors that says
iadfuqgraphicsview.h:14: error: expected `,' or `...' before '*=' token
iadfuqgraphicsview.cpp:4: error: prototype for `IADFUQGraphicsView::IADFUQGraphicsView(QGraphicsS cene*, QWidget*)' does not match any in class `IADFUQGraphicsView'
iadfuqgraphicsview.h:10: error: candidates are: IADFUQGraphicsView::IADFUQGraphicsView(const IADFUQGraphicsView&)
iadfuqgraphicsview.h:14: error: IADFUQGraphicsView::IADFUQGraphicsView(QGraphicsSc ene*, QWidget)

iadfuqgraphicsview.cpp

#include <QtGui>
#include "iadfuqgraphicsview.h"
IADFUQGraphicsView::IADFUQGraphicsView(QGraphicsScene *scene, QWidget* parent) :QGraphicsView(scene, parent) 
{
}

#include <QtGui>
#include "iadfuqgraphicsview.h"
IADFUQGraphicsView::IADFUQGraphicsView(QGraphicsScene *scene, QWidget* parent) :QGraphicsView(scene, parent) 
{
}

But I told you to include QGraphicsView in the header.

[sincnarf]

same error. sorry kind of sleepy here.

I tried to place
#include <QtGui/QGraphicsView>

also tried to place
#include <QGraphicsView>

also tried the forward declaration
class QGraphicsView;

still got the same error as before
iadfuqgraphicsview.h:16: error: expected `,' or `...' before '*=' token
iadfuqgraphicsview.cpp:4: error: prototype for `IADFUQGraphicsView::IADFUQGraphicsView(QGraphicsS cene*, QWidget*)' does not match any in class `IADFUQGraphicsView'

iadfuqgraphicsview.h:16: error: IADFUQGraphicsView::IADFUQGraphicsView(QGraphicsSc ene*, QWidget)

Try this:

the header(customgv.h):

#ifndef CUSTOMGV_H
#define CUSTOMGV_H
 
#include <QGraphicsView>
 
class QWidget;
class QGraphicsScene;
 
class customgv : public QGraphicsView
{
    Q_OBJECT
 
public:
    customgv(QGraphicsScene*, QWidget*= NULL);
    ~customgv();
};
#endif

#ifndef CUSTOMGV_H
#define CUSTOMGV_H

#include <QGraphicsView>
 
class QWidget;
class QGraphicsScene;
 
class customgv : public QGraphicsView
{
    Q_OBJECT
   
public:
    customgv(QGraphicsScene*, QWidget*= NULL);
    ~customgv();
};
#endif

To copy to clipboard, switch view to plain text mode 

the cpp(customgv.cpp):

#include <QtGui>
      #include "customgv.h"
      customgv::customgv(QGraphicsScene *scene, QWidget* parent) :QGraphicsView(scene, parent)
      {
      }

#include <QtGui>
      #include "customgv.h"
      customgv::customgv(QGraphicsScene *scene, QWidget* parent) :QGraphicsView(scene, parent)
      {
      }

You might have another class named IADF...
