QTreeWidgetItem one icon + one icon button

[Alundra]

Hi,
I have a QTreeWidget with each element has an icon.
I have an option to set visible or not the data each element of tree widget item has.
The goal is to have the visible button then the icon then the name.
I tried to add a column and set a widget using QToolButton but I got problem :

How achieve that correctly ?
Thanks for the help

I don't know if it is possible with a QTreeWidget (i only use QTreeView with a self made TreeModel)

If you use a QTreeView with a self made model you can attach a QStyledItemDelegate to the view that adds a button in a cell

If you don't want to make a column in your model just for a view item you can attach a modified proxymodel that adds a virtual column just for the button (I did this for a table view http://www.qtcentre.org/threads/60783-QTableView-add-a-remove-button-to-each-row)
