learn row of qtablewidget

[ahmetturan]

i add pushbutton to qtablewidget with this code:

QPushButton *btn=new QPushButton();
ui->tableWidget->setCellWidget(currentRow,0,btn);

QPushButton *btn=new QPushButton();
ui->tableWidget->setCellWidget(currentRow,0,btn);

To copy to clipboard, switch view to plain text mode 

when i click the button how can i learn its row?
ui->tableWidget->row(btn) does not work. because btn is not qtablewidgetitem
