How can I get data from the hidden column in a QTreeView?

Alternatively, you can store the ID as Qt::UserRole data for the model index: QAbstractItemModel::setData(). When you get notified of the selected index, you ask it for the UserRole data, which is returned as a QVariant.

Oh, I tried to do what you described.. It works only while my column is visible...

hm... I'll try it, thanks!

Are you using a proxy model to convert the DB result into something to display in the tree?

I am creating QStandardItem and recursively appending rows..

child_node = QtGui.QStandardItem("ITEM TEXT")
root.appendRow(child_node)

"ITEM TEXT" - is getting directly from sqlite...for each iteration...

[d_stranz]

Well then it is easy - when you create the QStandardItem, just call

child_node.setData( QVariant( ID ), Qt::UserRole )

child_node.setData( QVariant( ID ), Qt::UserRole )

To copy to clipboard, switch view to plain text mode 

When you get the selected item, then it is just

ID = selected_node.data( Qt::UserRole )

ID = selected_node.data( Qt::UserRole )

To copy to clipboard, switch view to plain text mode 

(or whatever the appropriate syntax is - I'm not a python programmer).

It works! Thanks! This is exactly what I need..

child_node.setData(QtCore.QVariant(str(chld["ID"]))) #setting data

selected_id = str(index.model().itemFromIndex(index).data().toSt ring()) #getting data
