Implement custom tree/table header view to support filtering on columns

[prasad_N]

Hi all,
I want custom header view for my tree/table view like in the attachment, I want to show a line edit below the each column header so that use can filter on each column by entering text into the line edit.
I tried with delegate & came to know that delegate can't work with QHeaderView, so tried other ways also they really didn't work.

what is the best way to achieve this, If I need to customize the QHeaderView, what are the functions I need to re-implement ?

Thanks in the advance.
