Problem in activating a combobox at run time.

Your code is very error prone (like static casting to QComboBox). Maybe try simplifying it first to make sure something else doesn't affect it.

When i remove a row and than activate a combobox in row below than that row it give segmantaion fault while working fine above the removed row

It is difficult to understand what is going on there, but a common mistake is to use the same row index as it was before deletion, but keep in mind when you delete an item everything below it will have indexes decreased by one.

Can you debug the code and tell us the line number where does the error excatly occur?
