Vertical Header In tableview Problem

[Asad]

Dear All,
I am trying to resize the Vertical Header according to content.My table view is m_tableView.
for this I am using the code:
m_tableView->verticalHeader()->setSectionResizeMode(QHeaderView::ResizeToContents);
but that is not working.
I tried something other but that is a hook only.
Please can anyone suggest a solution.
Thanks.

Is it the width of the column you want to be bigger. If so you need to set this in the horizontal header(). And if not this, have you tried using a ItemDelegate and reimplementing the sizeHint
