[SOLVED] Can I return NULL in QItemDelegate::createEditor(...) ?

[yanbellavance]

In the following method for the following class:

@QWidget * QItemDelegate::createEditor ( QWidget * parent, const QStyleOptionViewItem & option, const QModelIndex & index ) const [virtual]
@

Just curious to know if it's a safe thing to do.

Why don't you just DON'T return Qt::ItemIsEditable from the model's flags() implementation?

well because I am using a QTableWidget but I ended up calling:

myTableWidget->item(row,col)->setFlags(Qt::ItemIsSelectable|Qt::ItemIsEnabled);

thanks.

You can safely return a null pointer (NULL or 0). Qt handles that case and your application will not crash.
