How to set height for QListWidget?

Question

Qt

There is a form on it QLineEdit and QListWidget placed in QVBoxLayout, sizePolicy fixed for QListWidget and method QSize sizeHint() const overridden;

QSize CommandListWidget::sizeHint() const
{
    return QSize(1, 1);
}

But for some reason, the size is not set to less than some value and it is clearly greater than 1 by 1.

Answer 1

Try setting a minimum size for the widget:
list.setMinimumSize(QSize(1, 1));

Answer 2

If there are more items in the list than the visible area, it is better not to use QListWidget, QTableWidget but only QListView and QTableView
