I am writing "SQLite" database and I create the database table like this:
void MainWindow::createdata()
{
QSqlQuery query;
query.exec("DROP TABLE messages");
query.exec("CREATE TABLE messages("
"id INTEGER PRIMARY KEY AUTOINCREMENT,"
"IPAddress VARCHAR(20),"
"date VARCHAR(10),"
"message VARCHAR(30))");
query.prepare("INSERT INTO messages(IPAddress, date, message) values(?,?,?)");
query.addBindValue("192.168.1.1");
query.addBindValue("jun 3 2016");
query.addBindValue("hello");
if (query.exec()) {
qDebug() << "ok!";
}
else
{
qDebug() << query.executedQuery();
qDebug() << query.lastError();
}
}
And i create "qtablewidget" like this:
QTableWidget* table = new QTableWidget();
table->setRowCount(10);
table->setColumnCount(4);
table->setWindowTitle("Received Message");
table->setSizePolicy(QSizePolicy::Expanding,QSizePolicy::Expanding);
table->setHorizontalHeaderLabels(QString("ID;HostAddress;Date;Message").split(";"));
table->setStyleSheet("QTableView {selection-background-color: blue;}");
table->setEditTriggers(QAbstractItemView::NoEditTriggers);
table->setSelectionBehavior(QAbstractItemView::SelectRows);
table->setSelectionMode(QAbstractItemView::SingleSelection);
QSqlQuery query("SELECT * FROM messages");
but i don't know how should i fill the "tablewidget" to show with query. Can anyone please help me?Thanks
