Making only one column of a QTreeWidgetItem editable

Question

I have a QTreeWidgetItem with two columns of data, is there any way to make only the second column editable? When I do the following:

QTreeWidgetItem* item = new QTreeWidgetItem();
item->setFlags(item->flags() | Qt::ItemIsEditable);

all columns become editable.

Answer 1

Looks like you will have to forgo using QTreeWidget and QTreeWidgetItem and go with QTreeView and QAbstractItemModel. The "Widget" classes are convenience classes that are concrete implementations of the more abstract but more flexible versions. QAbstractItemModel has a call flags(QModelIndex index) where you would return the appropriate value for your column.
