[solved] programatically expand a particular path in QTreeView
I have a QTreeView in combination with QFileSystemModel, showing the entire content of my computer (all drives on Windows).
@m_model = new QFileSystemModel(this);
m_treeView = new QTreeView(this);
I need to show the tree view expanded to initialPath from the beginning. I tried this:
But it works only when initialPath is one of the drives (like C:). In that case the drive is shown expanded.
I also tried this, which doesn't seem to work.
@auto rootIdx = m_model->setRootPath(initialPath);
Since the QFileSystemModel loading is threaded, I would rather call expand in a slot connected to "directoryLoaded":http://doc.qt.io/qt-5/qfilesystemmodel.html#directoryLoaded
Hope it helps
it also ensures that all parent nodes are expanded
QTreeView::scrollTo() does the trick!
directoryLoaded() wasn't helpful.
