Model/View one index.column as hidden UserRole

[doitux]

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:isplayRole of view-column 0 and model-column 2 as Qt:isplayRole of view-column 1.

Before in the treewidget i did it like this:

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());

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());

To copy to clipboard, switch view to plain text mode 

The model is build like this:

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"));
}

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"));
}

To copy to clipboard, switch view to plain text mode 

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

Best regards
Felix
