hi jpn,
today i m finally done with the border highlighting part. Thanks a lot for help.

But there is one more thing that is happening. i want that only the border is highlighted and not the background turns blue. i used the paint function and overrided it in my class's .cpp file. now one problem occurs.
the paint function paints the table created to white and not the color i selected. also it suppresses the effect of the drawFocus function and no focus is seen in the table.

i tried using palette in the table but can't make it work.

can u suggest somethng in that.

my code is as follows.


Qt Code: 
  1. //griddelegate.h
  2. class GridDelegate : public QItemDelegate 
  3. {
  4.  
  5. public:
  6.  
  7. 	GridDelegate(QObject *parent = 0);
  8.  
  9. 	void drawFocus(QPainter* painter, 
  10. 			const QStyleOptionViewItem &option, 
  11. 		const QRect &rect) const;
  12.  
  13. 	void paint(QPainter * painter, 
  14. 			const QStyleOptionViewItem & option, 
  15. 				const QModelIndex & index ) const;
  16.  
  17.  
  18. };

in the constructor of my main program, i merely call the setItemDelegate function as suggested by u.
