How do I make a QTableView readonly?

jdent

Hi,

I need to prevent the user to- editing the columns in a QTableView, yet I don't find setReadOnly(). How is this accomplished?

Regards,
Juan

Try :

tableView->setEditTriggers(QAbstractItemView::NoEditTriggers);

or in your item model :

Qt::ItemFlags  flags(const QModelIndex &index) const
               {
               return Qt::ItemIsEnabled;
               }

@jdent don't return that it's editable in flags()

@Christian-Ehrlicher No, that would make the model readonly - I only want the QTableView readonly...

Christian Ehrlicher

@jdent The flags are for the view. Please read the docs.

@Christian-Ehrlicher sorry did not find any info on ItemFlags for QTableView
can you please be more specific?

In Qt's model-view paradigm the flags are returned by the model: Qt::ItemFlags QAbstractItemModel::flags(const QModelIndex &index) const, values flags Qt::ItemFlags. Qt::ItemIsEditable determines whether the model tells the view items are editable or not. A view like QTableView will call this, behind the scenes without you doing anything, and make its interface correspond to what the model wants. @mpergand's implementation does not return Qt::ItemIsEditable so items won't be editable. QTreeView will show items as non-editable.
