Tabbed progra with pyqt

[viandante]

Hello!

I am trying to create a tabbed program with Pyqt4. The idea is that I want to be able to add python scripts in a folder. Those scritps should be then be accessible from a main framework/program. Finally, when I run the python script I want the window to be displayed in a tab of the main program.

Below you can find what I have got until now. It's a simple tree structure. When I double clik the second level items, I will run my script. At the moment the script runs in it's own dialog window. I would like it to run in a tab of the framework.

import sys
from PyQt4.QtCore import *

from prova import Ui_MainWindow


data = [("Hyperion related", [("Hyperion imports", [("Create tables", []), ("Create hyperion import file", [])])])]

	def __init__(self, parent=None):

		#Models

		fileSelectionModel =QItemSelectionModel(self.model, self.ui.treeView)
		self.ui.treeView.setSelectionModel(fileSelectionModel)

		self.model.setHorizontalHeaderLabels([self.tr("Object")])

		indexes = self.ui.treeView.selectedIndexes()
		if len(indexes) > 0:

			level = 0

				index = index.parent()
				level += 1

		menu = QMenu()
		if level == 0:
			entry=menu.addAction(self.tr("Edit person"))
			self.connect(entry,SIGNAL('triggered()'), lambda item="Edit person": self.doStuff())
		elif level == 1:
			menu.addAction(self.tr("Edit object/container"))
		elif level == 2:
