Choosing columns for display in an QSqlTableModel

[VRonin]

the code you posted is missing the necessary smodel->insertRows() smodel->inserColumns() are you doing it?

Hi
I don't have it. Whete is this supposed to go?
Thank you

Hi,

Why not just use a QSqlQueryModel and a QStyledItemDelegate ?

If you want to have specific names for the columns you are selecting then use the SELECT myColumn AS NewName construct.

QStandardItemModel *smodel = new QStandardItemModel(this); // maybe give it a parent to avoid memory leaks

for(int row1=0;query.next (); ++row1)
    {
if(row1==0){
const QSqlRecord qRec=query.record();
smodel->insertColumns(0,qRec.count());
Q_ASSERT(query.size()>=0) // if NO COUNT is set in the database then you have to calculate the size manually
smodel->inserRows(0,query.size());

// Optional: set headers
for(int i=0;i<qRec.count();++i)
smodel->setHeaderData(i,Qt::Horizontal,qRec.fieldName(i));
}
        smodel->setData (smodel->index(row1,0), NameD = query.value(0).toString ());
        qDebug() << "row1: " << row1;
        qDebug() << "NameD: " << NameD;
        Pixmap.loadFromData (query.value (1).toByteArray ());
        smodel->setData (smodel->index(row1,1),Pixmap,Qt::DecorationRole );
        smodel->setData (smodel->index(row1,2), DescrD = query.value (2).toString ());
        qDebug() << "DescrD: " << DescrD;
    }

Thank you very much for the code. Now it shows the column headers, but still no data.
I added

ui->tableView->setModel (smodel);

to view it in tableView.Any Idea why no records show?
Thank you.

Looks like rows are still mot inserted, try this:

for(int row1=0;query.next (); ++row1)
    {
if(row1==0){
const QSqlRecord qRec=query.record();
smodel->insertColumns(0,qRec.count());

// Optional: set headers
for(int i=0;i<qRec.count();++i)
smodel->setHeaderData(i,Qt::Horizontal,qRec.fieldName(i));
}

smodel->inserRow(row1);
        smodel->setData (smodel->index(row1,0), query.value(0).toString ());
        Pixmap.loadFromData (query.value (1).toByteArray ());
        smodel->setData (smodel->index(row1,1),Pixmap,Qt::DecorationRole );
        smodel->setData (smodel->index(row1,2), query.value (2).toString ());
    }

@VRonin
Thank you. This one displays data from the database but only one record (1 line). Trying to figure out why.

[gabor53]

Any idea why this code displays only 1 record from the database?

[SGaist]

Check your query and your database content.

@SGaist Thank you. I was missing a }.
