[Qt-interest] error: passing `const QLabel' as `this' argument of `void QLabel::setText(const QString&)' discards qualifiers

[Paul Colby]

QList::at() does indeed return a const T &, so that makes sense ;)

Try either of these instead:

label_list->value(i).setText("checked"); // or...
label_list[i].setText("checked"); // Might need to de-reference the
list_label pointer first?
