QTableView alignment items

[repaco]

Dear Wysota,
solved with item delegate. I post for newbie like me.

With QT Designer I've created a windows named voci with QTableview object named g_lista.

Then in voci.h I coded:

...more code..

#include <QItemDelegate>

#include <QItemDelegate>

To copy to clipboard, switch view to plain text mode 

...more code

class mycoldelegate : public QItemDelegate
{
    Q_OBJECT
 
public:
 
    mycoldelegate(QObject *parent);
 
    void paint(QPainter *painter,
               const QStyleOptionViewItem &option,
               const QModelIndex &index) const;
};

class mycoldelegate : public QItemDelegate
{
    Q_OBJECT

public:

    mycoldelegate(QObject *parent);

    void paint(QPainter *painter,
               const QStyleOptionViewItem &option,
               const QModelIndex &index) const;
};

In voci.cpp:

...more code...

void Voci::lista()          /* function retreving data from DB  */
{
    QSqlQueryModel *mod_grid = new QSqlQueryModel;
 
    mod_grid->setQuery("select * from voci order by ordine");
    mod_grid->setHeaderData(0, Qt::Horizontal, "Codice");
    mod_grid->setHeaderData(1, Qt::Horizontal, "Voce");
    mod_grid->setHeaderData(2, Qt::Horizontal, "Ordin.");
 
    ui->g_lista->setModel(mod_grid);
    ui->g_lista->setColumnWidth(0, 60);
    ui->g_lista->setColumnWidth(1, 200);
    ui->g_lista->setColumnWidth(2, 50);
 
    ui->g_lista->setItemDelegateForColumn(2, new mycoldelegate(this)); //Item Delegate
 
}

void Voci::lista()          /* function retreving data from DB  */
{
    QSqlQueryModel *mod_grid = new QSqlQueryModel;

    mod_grid->setQuery("select * from voci order by ordine");
    mod_grid->setHeaderData(0, Qt::Horizontal, "Codice");
    mod_grid->setHeaderData(1, Qt::Horizontal, "Voce");
    mod_grid->setHeaderData(2, Qt::Horizontal, "Ordin.");

    ui->g_lista->setModel(mod_grid);
    ui->g_lista->setColumnWidth(0, 60);
    ui->g_lista->setColumnWidth(1, 200);
    ui->g_lista->setColumnWidth(2, 50);

    ui->g_lista->setItemDelegateForColumn(2, new mycoldelegate(this)); //Item Delegate

}

mycoldelegate::mycoldelegate(QObject *parent)
    :QItemDelegate(parent)
{
}
 
void mycoldelegate::paint(QPainter *painter,
                 const QStyleOptionViewItem & option,
                 const QModelIndex & index) const
{
 
    QString text = index.model()->data(index, Qt::DisplayRole).toString();
          QStyleOptionViewItem myOption = option;
          myOption.displayAlignment = Qt::AlignRight | Qt::AlignVCenter;
 
        drawDisplay(painter, myOption, myOption.rect,
        text);
        drawFocus(painter, myOption, myOption.rect);
 
}

mycoldelegate::mycoldelegate(QObject *parent)
    :QItemDelegate(parent)
{
}

void mycoldelegate::paint(QPainter *painter,
                 const QStyleOptionViewItem & option,
                 const QModelIndex & index) const
{

    QString text = index.model()->data(index, Qt::DisplayRole).toString();
          QStyleOptionViewItem myOption = option;
          myOption.displayAlignment = Qt::AlignRight | Qt::AlignVCenter;

        drawDisplay(painter, myOption, myOption.rect,
        text);
        drawFocus(painter, myOption, myOption.rect);

}

Thank for help.
