[RameshNani]

Hi All,

My window desing like Frozen View and QTable View are side by side . in frozen View we only shows Frozen columns , remaining all shows in QTableView .
The Frozen Columns list is not stable , it will change in different nested levels .

I am using below code , can you sugest me on this issue . I faced issue mostly , like in 1st level i have 2 frozen columns , 2nd level one column and 3rd level 1 one column . when i go back from 3rd to 2nd it's working fine . when i go back from 2nd to 1st one column showing and other one gonna hide . Please help me .
