【QT中判断table Widget复选框状态】

QT中判断table Widget复选框状态

1. 设置table widget复选框及其行数，列数，内容填充，表头

//设置行数
ui->tableWidget->setRowCount(5);
//设置列数
ui->tableWidget->setColumnCount(6);
//设置表头
QStringList header;
header <<"标题1"<<"标题2"<<"标题3"<<"标题4"<<"标题5"<<"标题6";
ui->tableWidget->setHorizontalHeaderLabels(header);
//隐藏第五列
ui->tableWidget->setColumnHidden(4,true);
//填充内容，及设置复选框
for(int crow=0; crow<5;crow++)
{
    //第一列设置为复选框
    QTableWidgetItem *check = new QTableWidgetItem(QString(""));
    check->setCheckState(Qt::Unchecked);
    ui->tableWidget->setItem(crow, 0 ,check);
    //填充其他列的内容
    ui->tableWidget->setItem(crow,1,new QTableWidgetItem("3"));
    ui->tableWidget->setItem(crow,2,new QTableWidgetItem("2"));
    ui->tableWidget->setItem(crow,3,new QTableWidgetItem("1"));
    ui->tableWidget->setItem(crow,4,new QTableWidgetItem("5"));
}

2.判断复选框是否被选中

void MainWindow::on_pushButton_clicked()
{
    bool flag = 0;
    QTableWidgetItem *cellItem;
    for(int i= 0; i<5; i++)
    {
        //cellItem定位到第一列
        cellItem = ui->tableWidget->item(i,0);
        //判断第一列的循环中状态
        flag = cellItem ->checkState();
        if(flag ==1)
        {
            qDebug()<<"选中了："<
