[PyQt] Examples for uic module in PyQt

[Shriramana Sharma]

I would like to contribute the following examples for the PyQt 
documentation. They relate to using the uic module.

-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-

When using PyQt4.uic.loadUi, the following examples apply:

In the direct approach:

-------------------------------------------------------------------------
#! /usr/bin/env python

import sys
from PyQt4 import QtGui, uic

app = QtGui.QApplication(sys.argv)
window = uic.loadUi("imagedialog.ui")
window.show()

sys.exit(app.exec_())
-------------------------------------------------------------------------

In the single inheritance approach:

-------------------------------------------------------------------------
#! /usr/bin/env python

import sys
from PyQt4 import QtCore, QtGui, uic

class ImageDialog(QtGui.QDialog):
     def __init__(self):
         QtGui.QDialog.__init__(self)

         # Set up the user interface from Designer.
         self.ui = uic.loadUi("imagedialog.ui")
	self.ui.show()

         # Make some local modifications.
         self.ui.colorDepthCombo.addItem("2 colors (1 bit per pixel)")

         # Connect up the buttons.
         self.connect(self.ui.okButton, QtCore.SIGNAL("clicked()"),
                      self, QtCore.SLOT("accept()"))
         self.connect(self.ui.cancelButton, QtCore.SIGNAL("clicked()"),
                      self, QtCore.SLOT("reject()"))

app = QtGui.QApplication(sys.argv)
window = ImageDialog()
sys.exit(app.exec_())
-------------------------------------------------------------------------

-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-

I hope these are useful. I never tried the multiple inheritance approach 
but I presume it would work out similar to the single inheritance 
approach. Please also take this as a request to improve the PyQt uic 
module documentation. Thank you.
