Delete if row checked

I try created my own model for add checkbox in first column tableview.

Code:

---

#ifndef MODELANGGOTA_H
#define MODELANGGOTA_H
 
#include <QSqlQueryModel>
 
class modelAnggota : public QSqlQueryModel
{
    Q_OBJECT
 
public:
    	modelAnggota(QObject *parent = 0);
	QVariant data(const QModelIndex &item, int role) const;
 
};
 
#endif // MODELANGGOTA_H

---

Code:

---

#include "modelanggota.h"
 
modelAnggota::modelAnggota(QObject *parent)
     : QSqlQueryModel(parent)
{
 
}
 
QVariant modelAnggota::data(const QModelIndex &index, int role) const
{
     if (role == Qt::CheckStateRole && index.column() == 0)
        return Qt::Unchecked;
 
     return QSqlQueryModel::data(index, role);
}

---

Code:

---

QSqlQueryModel *model = new modelAnggota();
model->setQuery("select * from mailbox");
 
ui->tableView->setModel( model );
ui->tableView->setSelectionBehavior(QAbstractItemView::SelectRows);
ui->tableView->setAlternatingRowColors(TRUE);
ui->tableView->setSelectionMode(QAbstractItemView::SingleSelection);
ui->tableView->setEditTriggers(QAbstractItemView::NoEditTriggers);

---

But checkbox can't checked or unchecked. I need the checkbox not for edited data on table (database), but just for checked. Then, if I Click a pushButton (delete button), row with checked will remove. And yes, row in database table will removed too.


Have any suggestion ?

Sorry. my english is bad :)

You should look at the QAbstractItemModel::flags method and return Qt::ItemIsUserCheckable and possibly some other flags for the check box column.

You mean like this ? Ah, not work.

Code:

---

Qt::ItemFlags modelAnggota::flags(const QModelIndex &index) const
 {
     if (index.column()==0)
         return Qt::ItemIsEditable|Qt::ItemIsEnabled|Qt::ItemIsSelectable|Qt::ItemIsUserCheckable;
 
 
	return QAbstractItemModel::flags(index);
 
 }
