Re: pyZui - anyone know about this?
Hi, Yes, the toolkit used is PyQt. The ZUI is implemented using a simple QPainter, and employs pyramidal tiling for efficiency (I haven't used any Qt/KDE voodoo in this regard). I'm using Gnome at the moment, but it should work just as well on KDE. Web pages are rendered using QtWebKit, and PDF with the pdftoppm utility. The project is opensource (GPLv2), but just hasn't been published yet :) . I'll try to make a release over the next few days, and I'll post a link here when I do. -- David Roberts http://da.vidr.cc/ On Dec 15, 10:33 am, Donn wrote: > On Tuesday 15 December 2009 01:43:52 David Boddie wrote:> I managed to catch > his address and sent him a message saying that people > > were discussing PyZUI in this thread. > > Oooh.

Sure, it was just a quick mockup of a potential application.

Obviously there will be some applications that suit more traditional GUIs better than ZUIs, just like there's plenty of applications more suited to the command-line than a GUI. After all, things such as the web and the desktop metaphor came into being long before ZUIs.

OverflowError in RLock.acquire()
Hi, I'm trying to port a Python application to Windows, and I'm getting the following error (which did not occur when running on Linux): Exception in thread Thread-4: Traceback (most recent call last): File "C:\Python26\lib\threading.py", line 525, in __bootstrap_inner self.run() File "C:\Documents and Settings\David\My Documents\pyzui\pyzui\tileprovider.py", line 97, in run self.__tilecache[tile_id] = Tile(tile) File "C:\Documents and Settings\David\My Documents\pyzui\pyzui\tilecache.py", line 165, in __setitem__ with self.__lock: File "C:\Python26\lib\threading.py", line 115, in acquire me = current_thread() File "C:\Python26\lib\threading.py", line 803, in currentThread return _active[_get_ident()] OverflowError: can't convert negative value to unsigned long Where __lock is an RLock object. The error only occurs for a single class (which is derived from the TileProvider class in tileprovider.py, which in turn is derived from threading.Thread), which would lead me to believe that there's an error in my code, but the traceback doesn't help much, and I haven't been able to find any similar problems with google. Any help would be appreciated. -- David Roberts http://da.vidr.cc/ -- http://mail.python.org/mailman/listinfo/python-list

Re: idiom for list looping
To the best of my knowledge the second way is more pythonic - the first is a little too reminiscent of C. A couple of notes: - you don't need the parentheses around "i, e" - if you were going to use the first way it's better to use xrange instead of range for iteration -- David Roberts http://da.vidr.cc/ On Wed, Jul 29, 2009 at 19:02, superpollo wrote: > hi clp. > > i want to get from here: > > nomi = ["one", "two", "three"] > > to here: > > 0 - one > 1 - two > 2 - three > > i found two ways: > > first way: > > for i in range(len(nomi)): > print i, "-", nomi[i] > > or second way: > > for (i, e) in enumerate(nomi): > print i, "-", e > > which one is "better"? is there a more pythonic way to do it? > > bye > > ps: > > m...@192.168.1.102:~/test$ python -V > Python 2.3.4 > m...@192.168.1.102:~/test$ uname -a > Linux fisso 2.4.24 #1 Thu Feb 12 19:49:02 CET 2004 i686 GNU/Linux > m...@192.168.1.102:~/test$ > -- > http://mail.python.org/mailman/listinfo/python-list > -- http://mail.python.org/mailman/listinfo/python-list
