我在QTableWidet中添加了一个QComboBox
          QComboBox *ziduan = new QComboBox;
          tableWidget->setCellWidget(rowNum,1,ziduan);
我想在currentIndexChanged信号中获取comboBox所在的行,列。
    int col = 1;
          int row=1;
           QSignalMapper* signalMapper = new QSignalMapper(this); 
          connect(ziduan, SIGNAL(currentIndexChanged(int)), signalMapper, SLOT(map())); 
          signalMapper->setMapping(ziduan, QString("%1-%2").arg(rowNum).arg(col)); 
          connect(signalMapper, SIGNAL(mapped(const QString &)),this, SIGNAL(changeZiduan(const QString &)));
void sqlGenerator::changeZiduan(const QString &position)
{
           QStringList coordinates = position.split("-"); 
           int row = coordinates[0].toInt(); 
           int col = coordinates[1].toInt(); 
}
这样写不起作用,改变index的时候,并没有响应changZiduan函数。
哪位高手能帮忙解决一下。只要能获取comboBox所在的行,列。
