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.

Thanks,

I was thinking Q_OBJECT macro is used for Signals and Slots.

I have one more doubt about width and height of each cell in QTableWidget. Except using methods like setColumnWidth(), setRowHeight(), is there any function which will create all cell of same width and height.

Thanks

It is, but the problem was that you didn't declare ChooseColor() and ExecPopupMenu( int, int ) as slots.

Except using methods like setColumnWidth(), setRowHeight(), is there any function which will create all cell of same width and height.

You could try changing the size hint for QTableWidgetItems.
