C::B+QT "undefined reference to vtable"

[alfre]

    I'm sorry my english, I speak spanish.

     I use C::B + Qt on Linux,
     when I try to do my own public slots method I got an Error :  "undefined reference to vtable"  WHY???

                                                               THANKS FOR YOU HELP!!!!!!
HERE the code:

#ifndef COUNTER_H_INCLUDED
#define COUNTER_H_INCLUDED

#include <QtGui>   //include todo

class Counter : public QWidget
{
   Q_OBJECT

private:
     QPushButton * but1;
     QPushButton * but2;

public :
     Counter() : QWidget()
   {
          
         but1 = new QPushButton("the 1", this);
         but1->setGeometry(10,50,100,50);
        
         but2 = new QPushButton("the 2", this);
    but2->setGeometry(200,50,100,50);

   QObject::connect(but1, SIGNAL(clicked()), this, SLOT(Esconder2()));
      }

public slots:
       void Esconder2(){ but2->hide(); }

};

#endif // COUNTER_H_INCLUDED

This can arrive when you didn't declare and implement a destructor (virtual or not) and you defined your own contructor. I am not at home to test that with your code but, hope it helps !

It may also be that you mixed object files compiled with- and without the debug switch. Try a re-build.

#ifndef COUNTER_H_INCLUDED
#define COUNTER_H_INCLUDED

#include <QtGui>   //include todo

try
#ifndef COUNTER_H_INCLUDED
#define COUNTER_H_INCLUDED

#include <QtGui/QWidget>
#include <QtGui/QPushButton>

or
#ifndef COUNTER_H_INCLUDED
#define COUNTER_H_INCLUDED

#include <QWidget>
#include <QPushButton>

if you use your own slots, read info about MOC utility and add to Pre-Build step moc-info file generation
