windows下QT中如何删除tableview中的选中行

[萝卜条]

如题，纠结这个问题好久了，各位大神们给点意见。。。。。以下是函数代码
void MainWindow::on_deleteButton_clicked()
{
int curRow = ui->tableView->currentIndex().row();

QModelIndex index = ui->tableView->currentIndex();

int id=index.sibling(curRow,4).data().toInt();


QSqlQuery query;

query.prepare("delete from table where id =:id ");

query.bindValue(":id",id);
bool ok=query.exec();
if(ok)
{
qDebug()<<"delete success";
}
else
{
qDebug()<<"delete error"<<query.lastError().text();

}
}

QStandardItemModel *model = new QStandardItemModel(); ui->tableView->setModel(model); . . . int curRow = ui->tableView->currentIndex().row(); model->removeRow(curRow); 视图模型，model实现对数据的操作。

void XXX::DeleteITEM() { QItemSelectionModel *selectionModel = table_view->selectionModel(); if (selectionModel->hasSelection()) { QModelIndexList indexList = selectionModel->selectedIndexes(); QModelIndex index = indexList.at(1); // 第几列 QString strTaskName = index.data().toString(); qDebug() << strTaskName; } else { QMessageBox::information(NULL, tr("Information"), tr("not select")); } }

[zack8712]

void MainWindow::deleteItem() { QModelIndex index = treeView->selectionModel()->currentIndex(); treeModel->removeRow(index.row(), index.parent()); }

搞出来了，只是换了种方法 QSqlQuery query; // query.prepare("delete from student where id = 2"); // query.bindValue(curRow); int curRow = ui->tableView->currentIndex().row(); QModelIndex index = ui->tableView->currentIndex(); int id=index.sibling(curRow,0).data().toInt(); qDebug("shuzi is %d",id); query.prepare("delete from information where id = :id"); query.bindValue(":id",id);
