how to suppress model::data DecorationRole when the QTableView cell editor is active

[davidb]

Turns out to be very easy. I reimplemented updateEditorGeometry in the delegate as follows, and that took care of it!

void MapTextDelegate::updateEditorGeometry(QWidget *editor, const QStyleOptionViewItem &option, const QModelIndex &index) const { 
  QStyledItemDelegate::updateEditorGeometry(editor, option, index); 
  editor->setGeometry(option.rect); 
}

void MapTextDelegate::updateEditorGeometry(QWidget *editor, const QStyleOptionViewItem &option, const QModelIndex &index) const { 
  QStyledItemDelegate::updateEditorGeometry(editor, option, index); 
  editor->setGeometry(option.rect); 
}
