It's hard to help you since you didn't show us any of your code.

This works fine for me:

#include <QtGui>
 
class Dummy : public QObject {
  Q_OBJECT
public:
  Dummy() : QObject() {}
public slots:
  void check(const QModelIndex &parent, int start, int end) {
    qDebug() << Q_FUNC_INFO << start << end;
  }
};
 
#include "main.moc"
 
int main(int argc, char **argv) {  
  QCoreApplication app(argc, argv);
  QStandardItemModel model(4,2);
  Dummy d;
  QObject::connect(&model, SIGNAL(rowsAboutToBeRemoved(QModelIndex, int, int)), &d, SLOT(check(QModelIndex, int, int)));
  model.removeRow(0);
  return 0;
}

#include <QtGui>

class Dummy : public QObject {
  Q_OBJECT
public:
  Dummy() : QObject() {}
public slots:
  void check(const QModelIndex &parent, int start, int end) {
    qDebug() << Q_FUNC_INFO << start << end;
  }
};
 
#include "main.moc"

int main(int argc, char **argv) {  
  QCoreApplication app(argc, argv);
  QStandardItemModel model(4,2);
  Dummy d;
  QObject::connect(&model, SIGNAL(rowsAboutToBeRemoved(QModelIndex, int, int)), &d, SLOT(check(QModelIndex, int, int)));
  model.removeRow(0);
  return 0;
}

To copy to clipboard, switch view to plain text mode 

Result: void Dummy::check(const QModelIndex&, int, int) 0 0
