@Qt-embedded-developer
since you need to create a custom widget subclassed from QTableWidget and override a method from it you cant use the designer directly (unless you create a custom plugin for it)
But you can add the widget on runtime into the layout. The layout is defined in the designer. Access the layout via the ui variable and call addWidget() on it. -

ok, i see.
Alternatives are:Via the view:
Subclass your item view and reimplement QAbstractItemView::selectionCommand() and always returnQItemSelectionModel::NoUpdatein it.Via model:
Create a custom QSortFilterProxyModel subclass and reimplement QSortFilterProxyModel::flags():Qt::ItemFlags NoSelectionModel::flags(const QModelIndex &index) const { return QSortFilterProxyModel::flags(index) & ~Qt::ItemIsSelectable; } -
