Problem with custom widget

[jacek]

It probably creates the right object, but your custom widget is wrong.

It should be:

class SpreadSheet : public QTableWidget
{
   Q_OBJECT
   public :
      SpreadSheet( QWidget* a_parent = 0 );
      SpreadSheet( int a_row = 1, int a_column = 4, QWidget *a_parent = 0 );
      void CreatePopupMenu();
 
   private slots:
      void ChooseColor();
      void ExecPopupMenu( int, int );
 
   private:
      unsigned row;
      unsigned column;
      Q3PopupMenu *menu;
      QAction *colorBackAct;
      QAction *colorTextAct;
      QColor color;
 };

class SpreadSheet : public QTableWidget
{
   Q_OBJECT
   public :
      SpreadSheet( QWidget* a_parent = 0 );
      SpreadSheet( int a_row = 1, int a_column = 4, QWidget *a_parent = 0 );
      void CreatePopupMenu();

   private slots:
      void ChooseColor();
      void ExecPopupMenu( int, int );

   private:
      unsigned row;
      unsigned column;
      Q3PopupMenu *menu;
      QAction *colorBackAct;
      QAction *colorTextAct;
      QColor color;
 };

To copy to clipboard, switch view to plain text mode 

PS. Next time, please, use [ code ] tags to make your code readable.
