Qt hide column in QTableView
提问by laura
I want to hide the IDcolumn in the QtableViewand i can't do that on my implementation. Can anyone help me?
我想隐藏 中的ID列，但QtableView在我的实现中无法做到这一点。谁能帮我？
void MainWindow::on_actionClear_Search_triggered()
{
model = new QStandardItemModel(cars.size(),6,this);
//create header
createHeader(model);
//set data to the table view
populate(cars);
ui->tableView->setColumnHidden(6,true);
ui->tableView->setModel(model);
}
void MainWindow::createHeader(QStandardItemModel *model){
model->setHorizontalHeaderItem(0,new QStandardItem("Car"));
model->setHorizontalHeaderItem(1, new QStandardItem("Type"));
model->setHorizontalHeaderItem(2, new QStandardItem("Mileage"));
model->setHorizontalHeaderItem(3, new QStandardItem("Year"));
model->setHorizontalHeaderItem(4, new QStandardItem("Is registered"));
model->setHorizontalHeaderItem(5, new QStandardItem("ID"));
}
void MainWindow::populate(const QList<Vehicle> &vehicles)
{
int j = 0;
QList<Vehicle>::ConstIterator iter;
for( iter= vehicles.begin(); iter != vehicles.end(); iter++){
const Vehicle& car = *iter;
//set car
QString makeAndModel = car.getGeneralData().getMake() + car.getGeneralData().getModel();
QStandardItem *mAndM = new QStandardItem(QString(makeAndModel));
mAndM->setEditable(false);
model->setItem(j,0,mAndM);
//set type
QStandardItem *type = new QStandardItem(QString(car.getGeneralData().getType()));
type->setEditable(false);
model->setItem(j,1,type);
//set mileage
QString mileageString = QString::number(car.getGeneralData().getMileage());
QStandardItem *mileage = new QStandardItem(QString(mileageString));
mileage->setEditable(false);
model->setItem(j,2,mileage);
//set year
QString yearString = QString::number(car.getGeneralData().getYear());
QStandardItem *year = new QStandardItem(QString(yearString));
year->setEditable(false);
model->setItem(j,3,year);
//set registration
QString regString = VehicleHelper::convertBoolToString(car.getRegistration().isRegistered());
QStandardItem *regDate = new QStandardItem(QString(regString));
regDate->setEditable(false);
model->setItem(j,4,regDate);
//set ID column
QStandardItem *idNumber = new QStandardItem(QString(car.getVehicleID().getID()));
idNumber->setEditable(false);
model->setItem(j,5,idNumber);
j++;
}
}

You use ui->tableView->setColumnHidden(6, true);, but there is no column with index 6. You should write ui->tableView->setColumnHidden(5, true);instead, because ID column number is rather 5than 6.
您使用ui->tableView->setColumnHidden(6, true);，但没有索引为 6 的列。您应该改写ui->tableView->setColumnHidden(5, true);，因为 ID 列号是5而不是 6。
UPDATE:
更新：
You also need to hide column(s) after you set the model to the view, i.e:
将模型设置为视图后，您还需要隐藏列，即：
ui->tableView->setModel(model);
ui->tableView->setColumnHidden(5, true);
