做数据库的话 QtableWidget 控件 应该用得很多的，做个记录
//QtableWidget 控件
//加水平表头
QStringList list1;
list1<<"姓名"<<"性别"<<"年龄";
ui->tableWidget->setColumnCount(list1.size());
ui->tableWidget->setHorizontalHeaderLabels(list1);
ui->tableWidget->setRowCount(10); //设行数
ui->tableWidget->setItem(0,0,new QTableWidgetItem("jinesc"));
QStringList nameList;
nameList<<"kiki"<<"jinesc"<<"bbb";
QList<QString> sexList;
sexList<<"女"<<"男"<<"未知";
for (int i=0;i<3;i++) {
int col=0;
ui->tableWidget->setItem(i,col++,new QTableWidgetItem(nameList[i]));
ui->tableWidget->setItem(i,col++,new QTableWidgetItem(sexList.at(i)));
ui->tableWidget->setItem(i,col++,new QTableWidgetItem(QString::number(i+20)));
}
connect(ui->addButton,&QPushButton::clicked,[=](){
bool isEmpty=ui->tableWidget->findItems("jinesc.cn",Qt::MatchExactly).empty();
if(isEmpty){
ui->tableWidget->insertRow(0);
int col=0;
ui->tableWidget->setItem(0,col++,new QTableWidgetItem("jinesc.cn"));
ui->tableWidget->setItem(0,col++,new QTableWidgetItem("网站"));
}else{
QMessageBox::warning(this,"警告","已经添加了jinesc.cn");
}
});
connect(ui->delButton,&QPushButton::clicked,[=](){
bool isEmpty=ui->tableWidget->findItems("jinesc.cn",Qt::MatchExactly).empty();
if(isEmpty){
QMessageBox::warning(this,"警告","已经删除了jinesc.cn");
}else{
//找到所在行
int row=ui->tableWidget->findItems("jinesc.cn",Qt::MatchExactly).first()->row();
ui->tableWidget->removeRow(row);
}
});
ui->tableWidget->editItem(ui->tableWidget->item(0,1));//编辑某个单元格运行如图
