HOWTO get a ComboBox in a TableView to activate on a single click?

scarleton

I have placed a ComboBox in a TableView. Currently the user needs to double click to get it into edit mode. What do I need to do get it into Edit mode with a single click?

You can change the editTrigger of the view.

Well, that is a good start, the only problem is that I don't want all cells to be editable. The best option I have found, which I am not a huge fan of, is to subclass the TableView and implement my own custom edit to return false for columns that I don't want to be editable. Is there a better way?

Hi,

You can try the following approach.

For your tableView change the editTrigger

@ui->tableView->setEditTriggers(QAbstractItemView::AllEditTriggers);@

Then you need to override the Flags function for your model. For eg i have :
@class MyStandardItemModel : public QStandardItemModel
{
public:
MyStandardItemModel();
protected:
Qt::ItemFlags flags(const QModelIndex &index) const;
};@

and in the implementation file you can write:

@Qt::ItemFlags MyStandardItemModel::flags(const QModelIndex &index) const
{
Qt::ItemFlags flags = QAbstractItemModel::flags(index);
if (index.column() == 2) /* here i want column no 2 only to be editable */
{
flags |= Qt::ItemIsEditable;
return flags;
}
return QAbstractItemModel::flags(index);
}@

This worked for me :)

Thank you! You provided me with the road map I needed to get my results. What I did differently was how I handled the flags. The key was to only enable the edit on the columns I wanted to allow editing. Works like a champ, thank you!!!

@Qt::ItemFlags InvoiceItemSqlModel::flags(const QModelIndex &index ) const
{
Qt::ItemFlags flags = QSqlTableModel::flags(index);

if( index.column() == productIdNo() ||
index.column() == qtyNo() ||
index.column() == priceNo())
flags |= Qt::ItemIsEditable;
else
flags &= ~Qt::ItemIsEditable;

return flags;
}@
