Use of QAbstractItemDelegate::closeEditor

Maybe you should reimplement QItemDelegate::createEditor() instead and assign the validator to the editor there?

The problem with that is that it still allows you to TAB to the next cell. It just doesn't store the data in the model. It doesn't provide any cursor control.

I finally solved the problem. QItemDelegate re-implements the virtual function eventFilter. So I just created a new class derived from QItemDelegate.
In eventFilter, if it's not a TAB key:

return QItemDelegate::eventFilter(editor, event);

return QItemDelegate::eventFilter(editor, event);

If it is a TAB and validates OK:

emit commitData(lineEdit);
emit closeEditor(lineEdit, QAbstractItemDelegate::EditNextItem);
return true;

emit commitData(lineEdit);
emit closeEditor(lineEdit, QAbstractItemDelegate::EditNextItem);
return true;

If not:

emit closeEditor(lineEdit, QAbstractItemDelegate::NoHint);
return true

emit closeEditor(lineEdit, QAbstractItemDelegate::NoHint);
return true
