As Andreas points out in his post, the QFileDialog static methods like
getExistingDirectory() use the native dialog, so only limited customization
is possible.

However, if you create a QFileDialog instance, you get a dialog that can
be customized - as long as you're happy messing with a live dialog.

For example, this should show a tree view with expandable directories that
you can select:

fd = QFileDialog()
tree = fd.findChild(QTreeView)
tree.setRootIsDecorated(True)
tree.setItemsExpandable(True)
fd.setFileMode(QFileDialog.Directory)
fd.setViewMode(QFileDialog.Detail)
result = fd.exec_()
if result:
  directory = fd.selectedFiles()[0]

Beware: if you double click on a directory, the dialog will navigate into it.
