How to get the row value from Qtable widget - qt

Question

Actually i am inserting combo box in one column on my table and when one of the combo box from the table is selected i want to get the row value . How this can be done ?
#include "mainwindow.h"
#include "ui_mainwindow.h"
#include"QComboBox"
#include "QDebug"
#include "QModelIndexList"
#include "QTableWidgetItem"
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
QComboBox *s = new QComboBox;
s->insertItem(1,"INt");
ui->tableWidget->setCellWidget(1,1,s);
}
MainWindow::~MainWindow()
{
delete ui;
}
void MainWindow::on_tableWidget_clicked(const QModelIndex &index)
{
qDebug("ROW %d",index.row());
}
I tried something like this but it didnt give the row value where i have inserted the combo box and from other places it was returning the row value

I'm not so sure what you are trying to achieve, but maybe you are looking for a ItemDelegate that can be set for specific rows or columns, but not for a specific element inside the table. Maybe the posted solution would help you to create minimal reproducible examples.
#include <QApplication>
#include <QComboBox>
#include <QDebug>
#include <QTableWidget>
#include <QStyledItemDelegate>
class ComboBoxDelegate : public QStyledItemDelegate{
public:
virtual QWidget* createEditor(QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index) const override
{
auto s = new QComboBox(parent);
s->insertItem(1, "First");
s->insertItem(2, "Second");
return s;
}
};
int main(int argc, char** args) {
QApplication app(argc, args);
auto table = new QTableWidget;
table->setRowCount(2);
table->setColumnCount(2);
table->setItemDelegateForColumn(0, new ComboBoxDelegate);
auto s = new QComboBox;
s->insertItem(1, "First");
s->insertItem(2, "Second");
table->setCellWidget(1, 1, s);
QObject::connect(table, &QTableWidget::itemChanged, [&](QTableWidgetItem* item) {
qDebug() << item->row();
});
table->show();
app.exec();
}
