Make sure you inherit from the classes correctly. In your case, you 
should inherit from the QTreeView class and then overload the method 
mouseDoubleClickEvent().

This snippet below works.

Best regards,

import sys
from PyQt4 import QtGui

class DirView(QtGui.QTreeView):
    def __init__(self, parent =None):
        QtGui.QTreeView.__init__(self, parent)
        self.model = QtGui.QDirModel()
        self.setModel(self.model)
        self.setGeometry(10,750,400,200)

    def mouseDoubleClickEvent(self, event):
        print "event"

if __name__ =="__main__":
    app = QtGui.QApplication(sys.argv)

    view = DirView()
    view.show()

    sys.exit(app.exec_())
