Solved How to get the row-index when click pushbutton in qtablewidget ?

[Limer]

QPushButton* TableWidget::createSettingBtn()
{
    QPushButton* btn = new QPushButton(tr("Settings"));
    btn->setStyleSheet("margin-left: 6px; margin-right: 6px; margin-top: 2px; margin-bottom: 2px;");
    
    return btn;
}

...

setCellWidget(0, 3, createSettingBtn());

...

When click Setting pushbutton, I will exec the corresponding settingDialog( I use QList to manage all settingDialogs ).

So, before I exec the settingDialog, I must get the row-index according to the clicked pushbutton. So I use QTableWidget::currentRow() to get the row-index, but it failed, because when I firstly exec the program and click the pushbutton, QTableWidget::currentRow() will return -1.

And then , I use QTableWidget's signals to get the row-index, such as cellActivated(int row, int column) etc..., but all failed.

So, How to get the row-index when click pushbutton in qtablewidget? Thanks in advance.
