[PyQt] treeview

[lucaberto at libero.it]

Hello can you explain me why if i do this :

import sys
from PyQt4 import QtCore, QtGui


if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    
    model = QtGui.QDirModel()
    tree = QtGui.QTreeView()
    tree.setModel(model)
    
    tree.setWindowTitle(tree.tr("Dir View"))
    tree.resize(640, 480)
    tree.show()
    
    sys.exit(app.exec_())

All works

But if i do this:

main file:

import sys
from PyQt4 import *
from PyQt4 import  QtGui
from form_rinomina_file_impl import Form
app = QtGui.QApplication(sys.argv)
form = Form()
form.show()
app.exec_()

Form implementation file :

# -*- coding: utf-8 -*-

"""
Module implementing Form.
"""

from PyQt4.QtGui import QWidget
from PyQt4.QtCore import pyqtSignature
import sys
from PyQt4 import QtCore, QtGui

from Ui_form_rinomina_file import Ui_Form

class Form(QWidget, Ui_Form):
    """
    Class documentation goes here.
    """
    def __init__(self, parent = None):
        """
        Constructor
        """
        QWidget.__init__(self, parent)
        self.setupUi(self)
    
    @pyqtSignature("")
    def on_pushButton_clicked(self):
        """
        Slot documentation goes here.
        """
        # TODO: not implemented yet
        #raise "Not implemented yet"
        self.faccio_lista()
    
    
    def faccio_lista(self):
        modello = QtGui.QDirModel()
        self.treeView.setModel(modello)


Qtdesigner compiled file

from PyQt4 import QtCore, QtGui

class Ui_Form(object):
    def setupUi(self, Form):
        Form.setObjectName("Form")
        Form.resize(QtCore.QSize(QtCore.QRect(0,0,659,300).size()).expandedTo(Form.minimumSizeHint()))

        self.treeView = QtGui.QTreeView(Form)
        self.treeView.setGeometry(QtCore.QRect(350,50,256,192))
        self.treeView.setObjectName("treeView")

        self.pushButton = QtGui.QPushButton(Form)
        self.pushButton.setGeometry(QtCore.QRect(40,50,75,25))
        self.pushButton.setObjectName("pushButton")

        self.retranslateUi(Form)
        QtCore.QMetaObject.connectSlotsByName(Form)

    def retranslateUi(self, Form):
        Form.setWindowTitle(QtGui.QApplication.translate("Form", "Form", None, QtGui.QApplication.UnicodeUTF8))
        self.pushButton.setText(QtGui.QApplication.translate("Form", "PushButton", None, QtGui.QApplication.UnicodeUTF8))



if __name__ == "__main__":
    import sys
    app = QtGui.QApplication(sys.argv)
    Form = QtGui.QWidget()
    ui = Ui_Form()
    ui.setupUi(Form)
    Form.show()
    sys.exit(app.exec_())

in the treeview nothing is show
