Model/View one index.column as hidden UserRole

Hi

I wanna switch from item-based QTreeWidget to model/view QTreeView.
I have a 3-column-model. I need to display model-column 0 as Qt::UserRole of view-column 0, model-column 1 as Qt::DisplayRole of view-column 0 and model-column 2 as Qt::DisplayRole of view-column 1.

Before in the treewidget i did it like this:

Code:

---

QTreeWidgetItem *item = new QTreeWidgetItem();        
item->setData(0, Qt::UserRole,  index.column(0).toString());
item->setData(0, Qt::DisplayRole,  index.column(1).toString());
item->setData(1, Qt::DisplayRole,  index.column(2).toString());

---

The model is build like this:

Code:

---

void myLessonNotesModel::refresh()
{
	setQuery("SELECT noteid, date, content FROM note ORDER BY date DESC");
	setHeaderData(0, Qt::Horizontal, QObject::tr("Datum"));
	setHeaderData(1, Qt::Horizontal, QObject::tr("Notiz"));
}

---

Can anybody tell me how to connect the model columns to different view columns in different roles?

Best regards
Felix

Reimplement the data() method and return proper data from within there. Reimplement columnCount() to report the proper number of columns. Alternatively implement a very simple proxy model based on QSortFilterProxyModel where you will do the same without touching your base model.

Thx. I will try QSortFilterProxyModel.
