Help on adding children to tree view

[vieraci]

I have a TreeView and set it to a SQL model based on QAbstractItemModel.
I want to add child items to a selected item from click event which recalls data from QSqlQueryModel.
I can't find the method to use.
QTreeWidgetItem has a method called addChild() but I don't know how to get the selected item from the treeView.

Documentation should become your friend. Take a look at QTreeWidget class.
It has


QTreeWidgetItem * currentItem () const

QSqlQueryModel is a read-only flat model. You won't be able to add children to it. You have to provide your own model or use QTreeWidget instead of QTreeView.

there is soooooo much !!

Thanks, I have solved it with wysota's reply (he seems to have all the answers) :(

I read in the docs that removeChild() removes the item but not delete it.
When the node is clicked, any existing child items will need to be removed before refreshing with a new query. Should I recursively delete them as they are removed, like in a for/while loop ?
