Using KWallet in PyQt4

Question

It would be great if someone could show me how to use KWallet with pyqt4

Answer 1

Python Command Line Tutorial

First, I'll show how kwallet can be used from the Python command line to read and write a password:

$ python # We import the necessary modules. >>> from PyKDE4.kdeui import KWallet >>> from PyQt4 import QtGui # We create a QApplication. We will not use it, but otherwise # we would get a "QEventLoop: Cannot be used without # QApplication" error message. >>> app = QtGui.QApplication([]) # We open the wallet. >>> wallet = KWallet.Wallet.openWallet( KWallet.Wallet.LocalWallet(), 0) # We create a folder in which we will store our password, # and set it as current. >>> wallet.createFolder('myfolder') True >>> wallet.hasFolder('myfolder') True >>> wallet.setFolder('myfolder') True # We read the password (which does not exist yet), write it, # and read it again. >>> wallet.readPassword('mykey') (0, PyQt4.QtCore.QString(u'')) >>> wallet.writePassword('mykey', 'mypassword') 0 >>> wallet.readPassword('mykey') (0, PyQt4.QtCore.QString(u'mypassword')) 

Tutorial as a Python module

Usually you want to create some simple functions for wrapping around kwallet methods. The following Python module can open a wallet, receive and set a password:

 #!/usr/bin/python from PyKDE4.kdeui import KWallet from PyQt4 import QtGui def open_wallet(): app = QtGui.QApplication([]) wallet = KWallet.Wallet.openWallet( KWallet.Wallet.LocalWallet(), 0) if not wallet.hasFolder('kwallet_example'): wallet.createFolder('kwallet_example') wallet.setFolder('kwallet_example') return wallet def get_password(wallet): key, qstr_password = wallet.readPassword('mykey') # converting the password from PyQt4.QtCore.QString to str return str(qstr_password) def set_password(wallet, password): wallet.writePassword('mykey', password) 

It can be used as follows:

 $ python >>> import kwallet_example >>> wallet = kwallet_example.open_wallet() >>> kwallet_example.set_password(wallet, 'mypass') >>> kwallet_example.get_password(wallet) 

Answer 2

Well, I found a good example about this in here , you will also need to use PyKDE4 not only PyQt.
