How to scroll to current index?

I am making a file browser using QTreeView and QFileSystemModel. It must be selected and scroll the tree to a selected item automatically. But it doesn't work scroll automatically without getting keyboard.

QString strFile = "/usr/bin/qmake";

QFileInfo fi(strFile);
QString dirFile = fi.dir().absolutePath();

QFileSystemModel model;
model.setRootPath("/");
model.setFilter(QDir::AllEntries | QDir::NoDotAndDotDot);

QTreeView view;
view.setModel(&model);
tree.setCurrentIndex(model.index(strFile));
tree.scrollTo(model.index(strFile));

view.show();

When executing above code, scroll is top but file is selected.

What's the problem not to scroll to selected item?

You can use scrollTo

view.scrollTo(view.currentIndex());

Optional pass the option where you want your item as a second parameter, like: QAbstractItemView::PositionAtTop or other

LE: i noticed that you actually call scrollTo, but you call it for some tree (that we can't see what it is) you should call that for view, same applies for setCurrentIndex.
