title: QTreeView : get a list of the items highlighted only (Multiple selection)
body: <p>I would like to get the folder pathes of a multiple selection. I wish to get only the ones that are highlighted when clicking. Ideally, a list would be updated interactively. I mean, if one folder is deselected, it is automatically removed from the list.</p>
  
  <p>Here an example of QTreeView below ... Can you provide support please?</p>
  
  <p>Thank you </p>
  
  <pre><code>from PyQt4 import QtCore, QtGui
  
  class Ui_Dialog(object):
      def setupUi(self, Dialog):
          Dialog.resize(1150, 905)
          self.gridLayout_2 = QtGui.QGridLayout(Dialog)
          self.groupBox     = QtGui.QGroupBox(Dialog)
          self.gridLayout   = QtGui.QGridLayout(self.groupBox)
          self.treeView     = QtGui.QTreeView(self.groupBox)
          self.gridLayout.addWidget(self.treeView, 0, 0, 1, 1)
          self.gridLayout_2.addWidget(self.groupBox, 0, 0, 1, 2)
          self.fileSystemModel = QtGui.QFileSystemModel(self.treeView)
          self.fileSystemModel.setFilter(QtCore.QDir.AllDirs | QtCore.QDir.NoDotAndDotDot | QtCore.QDir.AllEntries)
          self.fileSystemModel.setReadOnly(True)
          self.root = self.fileSystemModel.setRootPath('/home/')
          self.treeView.setModel(self.fileSystemModel)
          self.treeView.setRootIndex(self.root)
          self.treeView.setSelectionMode(QtGui.QAbstractItemView.ContiguousSelection)   
  
  if __name__ == "__main__":
      import sys

      ui.setupUi(Dialog)
      Dialog.show()
