QHeaderView setSectionResizeMode "segmentation fault"

[Evgeny Siberia]

Hi. I need ResizeToContents for VerticalHeader. My attempt:

QHeaderView *vHeader = new QHeaderView(Qt::Orientation::Vertical, this);
vHeader->setSectionResizeMode(Entity::SomeColumn, QHeaderView::ResizeToContents);
ui->_tv->setVerticalHeader(vHeader);

And I get segmentation fault in this line: setSectionResizeMode.
How I can set heigh for my rows by context?

I'm pretty sure it does not crash there but one line below. Please provide a minimal, compilable example to reproduce your problem.

The crash is probably caused by the fact that the view sections are not initialized until after you set the view's model. You must ensure that use of the two-parameter version of setSectionResizeMode happens after setModel. Take it out of the view constructor and put it somewhere else.
