如何在tablewidget添加按钮？

1 定义一个按钮

QPushButton * pBtn = new QPushButton();      

2 链接信号与曹

connect(pBtn, SIGNAL(clicked()), this, SLOT(OnBtnClicked()));      

3 按钮添加到单元格内

table->setCellWidget(0,0,pBtn); //如果点击按钮出现崩溃现象，就添加QTableWidgetItem  到按钮的那个单元格      

4 实现按钮的事件

void myPic::OnBtnClicked(void)
{
  QPushButton * senderObj=qobject_cast<QPushButton *>(sender());
  if(senderObj == 0)
  {
    return;
  }
  QModelIndex index =table->indexAt(QPoint(senderObj->frameGeometry().x(),senderObj->frameGeometry().y()));
  int row=index.row();
  qDebug()<<"row:"<<row;
}
