Starting a GUI application out of an console application

Hello! I am currently working on an alternative for the gnome-volume-manager for multiseat systems based on HAL and DBus. Whenever the signal 'DeviceAdded' is received I would like to start a GUI-Interface where the user can choose from different options. But now I am wondering how I should st

Recursive function returning a list

Hello! I have got a Python "Device" Object which has got a attribute (list) called children which my contain several other "Device" objects. I implemented it this way in order to achieve a kind of parent/child relationship. Now I would like to get all children of a given "Device" object and t

Flushing standard input

Splitting device addresses into parts

I often have to deal with strings like "PCI:2:3.0" or "PCI:3.4:0" and need the single numbers as tuple (2, 3, 0) or (3, 4, 0). Is there any simple way to achieve this? So far I am using regular expressions but I would like to avoid them ... Regards, Fabian Steiner -- ht

General Type Checks (int, str, tuple, etc.)

Hello! So far, I am using something like »if isinstance(var, int):« to determine, whether var's value is an integer. Now I would like to know if there is any better possibility to do such general checks or may a construct with isinstance() even fail in certain cases? Cheers, Fabian -- http://

Re: PyQt: QListView how to retrieve selected items?

Hi! Sorry for adopting your post for my own question, but since it is related to PyQT I think it's ok: Does anybody of you know where the openbook »GUI Programming with Python: QT Edition« has gone? It's not available any more: http://www.opendocs.org/pyqt/ points now to a non-existing site.

chmod directories recursively

Hello! As far as I can see os.chmod() doesn't adjust permissions on directories recusively. Is there any other possibility to achieve this aim except for calling os.system('chmod -R /dir') directly? Thanks, Fabian -- http://mail.python.org/mailman/listinfo/python-list

Creating an event loop

Hello! I am currently wondering how to write something like an "event loop". For example, if I want to write a function that checks whether a file was added or removed in a directory I would think of a "while 1: ..." construct that checks the mtime of the directory. Is this the right way to achiev
