And here in beginning of line 1. debugger says that "linemodel not accessible". Doesn't the *linemodel in constructor hold the data? And the private members are available to everywhere inside that class? This is inside a slot (shouldn't make any difference?)

Line oneline = linemodel->get(0);
qDebug() << oneline.article();

Line oneline = linemodel->get(0);
qDebug() << oneline.article();
