[Interest] QTreeView, QHeaderview, ResizeToContents and Interactive

[Etienne Sandré-Chardonnal]

Sorry, I wrote too fast

The proper way to get the column width ist tableView->sizeHintForColumn(i)

So just do

for(int i=0;i<header->count();++i)
    header->resizeSection(i, qMax(header->sectionSizeHint(i),
tableView->sizeHintForColumn(i)));
