QT实现点击表格控件获取位置

---

前言

上一章讲了使用setIndexWidget可以在表格中添加控件，当我们需要获取到点QCheckBox 控件在表格中的位置

---

一、核心代码

在生成控件的时候绑定信号

	QCheckBox *tempComboBox1 = new QCheckBox(this);
    tempComboBox1->setText("Yes");
    ui->tableView->setIndexWidget(m_modelProxy.index(1, 3), tempComboBox1);
    connect(tempComboBox1 , SIGNAL(stateChanged(int)) , this , SLOT(changTableButton(int)));

槽函数中获取坐标

void Widget::changTableButton(int state)
{
   QCheckBox *senderObj = qobject_cast<QCheckBox*>(sender());
   if(senderObj == nullptr){
       return;
   }
   if(Qt::Checked == state){
       qDebug() << "checked";
   }else if(Qt::Unchecked == state){
       qDebug() << "Unchecked";
   }


   int x = senderObj->frameGeometry().x();
   int y = senderObj->frameGeometry().y();
   QModelIndex index = ui->tableView->indexAt(QPoint(x, y));
   int row = index.row();
   int column = index.column();
   qDebug() << "row:" << row << "column:" << column;
}
