[solved] How to disable cells in QTableView

Hareen Laks

Dear all,

I have QTableView which created using QStandardItemModel.

I also create QSpinBox delegate to edit the cells data.

But I have to disable some SpinBoxes to avoid change value by user.

So my problem is how to disable some cells of QTabelView.

I find some were recommended to use
@tableView.setEditTriggers(QAbstractItemView::NoEditTriggers);@

But it disable entire TableView.

You can use
@void QStandardItem::setFlags(Qt::ItemFlags flags)@
for that. "Flags":http://qt-project.org/doc/qt-5/qt.html#ItemFlag-enum .

qxoz,

Thank you very much for your helping hand. Your solution is working fine.

I used below code.

@
for (int row = 0; row < rows().count(); ++row){
for (int col = 0; col < cols().count(); ++col){

     QModelIndex index = item_model->index(row,col,QModelIndex());

      if(toBeDisabled()){
             QStandardItem *my_item = item_model->itemFromIndex(index);
              my_item->setFlags(!Qt::ItemIsEditable);
      }
      else{
                table_view->openPersistentEditor(index);
      }
      item_model->setData(index,0);
 }

}@

Thanks again.

How do you write this code in PyQt ? I wish I could translate Qt to PyQt code by just looking at it, but I can't.

VRonin

model.item(row,column).setFlags(Qt.NoItemFlags)

I wish I could translate Qt to PyQt code

As a general rule if there is a symbol you don't understand replace it with . and it works :)

@Echeban
I see that the OP, @Hareen-Laks , wrote as his own solution 5 years ago:

my_item->setFlags(!Qt::ItemIsEditable);

If you're thinking of translating that into Python/PyQt, I wouldn't. 'coz it's wrong ;-) (Compiles but isn't the right code.)
