Hey ChrisW67,

Exactly you get my point ,star delegate is a good example but i guess i don't have to go through paint() and CreateEditor() because i just have to put the combobox in my 4th and 5th column. Please have a look at the following picture

I had followed the basic tecnique of TableView by QAbstractTableModel which display all my data perfectly , but with combobox its confusing me . I also thought to use the Combobox delegate but still confused in that.

thanks
