change Qtablewidget vertical header displayrole

[advseo32]

From QTableView obtain verticalHeader()
From the vertical header obtain the model()
From the model you can call setData() to change the text, colour, font, pixmap etc. of any vertical header entry.

You might need to use a QStyledItemDelegate on the table to signal when an editor is opened/close so that you can change the vertical header on that row.

i have use this

QModelIndex index ;
  index = tableau->model()->index(0,0) ;
  tableau->verticalHeader()->model()->setData(index,"*",Qt::DisplayRole);

QModelIndex index ;
  index = tableau->model()->index(0,0) ;
  tableau->verticalHeader()->model()->setData(index,"*",Qt::DisplayRole);

To copy to clipboard, switch view to plain text mode 

but the cell was changed not the cell in vertical header
