And it depends on what your trying to do. But a short list: -- a Python Binding for Quartz <http://tinyurl.com/9gfj8>. -- anti-grain <http://www.antigrain.com> has Tk, Wx, and PIL backends, as well. -- Python GD <http://tinyurl.com/de9la>. -- Python OpenGL <http://pyopengl.sourceforge.net>. I am sure I left many out.

SplashScreens...

I'll take a look and let you know. The only issue that might prevent me from exploring it is that this is a Cross-platform Windows/Macintosh application.... And since Quartz does not exist on the Windows side, I would have to explore a different solution there... - Benjamin

But.... I am not seriously researching it, and did not ask about it here... I am playing with some code... As to wxPython's Splashscreen... I was attempting to eliminate the need for wxPython during the "boot up" phase. So wxPython is not necessarily a perfect fit for the splashscreen... The application takes a few moments to start, and I want to get the splash screen as close to beginning as possible. That means not loading a lot of imported modules.. WxPython seems to be just *slightly* bulky... in that regard... If it had been possible, PIL just displaying a JPG would have been nice.. Since I don't use PIL, it was suprising to me that it required Tkinter to display an image... But in hindsight, it makes perfect since. We are not always perfect... - Benjamin

The question is, can I do it from Python? Could you clarify what you mean by a "Keyboard wedge"? Do you mean that it shows up on the USB bus as a keyboard? If so, you may not need to do anything.... I'll double check tonight... I have a USB barcode scanner that the MOSX detects as a keyboard.... I believe that MacPython / Python can read if from a simple readline.... - Benjamin

> Don't do that. Instead: > > - install Python 2.4.1 from http://undefined.org/python > - install PIL from http://www.pythonmac.org/packages I did that.... But it still didn't seem to work.... Then I remembered that 2.41 is /usr/local/bin/python2.4 ... The default is v2.3... So it was mostly user error.... But I don't think that PIL will help at this point... I'm attempting to add a splashscreen to an cross-platform (Windows / Mac) application... PIL appears to use Tkinter? Or at least the code that I found as a starting point is using Tkinter / PIL.... Since my application is using PythonCard / wxPython, I don't think that it would be a great idea to use anything that involves Tkinter..... Just as a lark... Here's the code that I was thinking of modeling from...

Newbie troubles with MacPython 2.4.1 / Tiger 10.4.3
by Mark Asbach Jan. 5, 2006

Jan. 5, 2006

Hi everybody, I know this should / could be a FAQ, but unfortunately I didn't find anything appropriate on the MacPython pages or the Python Wiki. Here's my problem: I started with a iMac G5 with all Apple updates installed. Then I installed MacPython-OSX-2.4.1-1, directly after that I installed the TigerPython24Fix-r2. Then I started up the PackageManager and tried to get those modules that I need. I successfully installed PIL-1.1.5- binary, but when I tried to install numarray-1.2.3-binary, the install failed. Now there's an incomplete numarray on my disk that fails to import into python2.4 with the error "no module named numarrayall". When I enable "Show Hidden" in PackageManager, the pseudo packages "WriteableBin-hidden" and "WriteableInclude-hidden" appear not to be installed. It's also interesting, that when I disable "For Current User Only", I get a warning that says "Install directory '/Library/ Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages' is not writeable or not readable". That's correct: iMac:~ asbach$ ll /Library/Frameworks/Python.framework/Versions/2.4/ lib/python2.4/site-packages total 8 -rw-r--r-- 1 root admin 119 Mar 31 2005 README Hm. Did I overlook something? What should I do to get numarray installed? chown the installed version of Python 2.4 so that I own them (instead of root), chmod g+w all modules, or do something more advanced? Thanks in advance, Mark

From Package Manager you obtain PIL. At least, that is what I read from the MacPython homepage. I never used PIL on the Mac. There are plenty of native Python binding to other (better?) imaging libraries. --Brian <http://brianray.chipy.org>

PIL for Python 2.4x? (Mac OS 2.4.x)

Folks, I am under the impression that PIL was bundled automatically with MacPython? Am I wrong? - Benjamin

Cleanest way to access IOKit from Python?
by David Warde-Farley Jan. 4, 2006

Jan. 4, 2006

I've been grokking the mailing list archives and I can't seem to find anything but vague references to IOKit. Basically, I want to mess with a USB Input device (it acts kind of like a keyboard wedge) directly. It seems like the best way to do this would be through IOKit. The question is, can I do it from Python? Is my best option writing a Python module in C and then calling that from my application? Thanks, - Dave

I keep reminding myself to start adding stuff :) BTW, what happened to the ReStructuredText as a formatting option on pythonmac.org wiki? I tried to add some Carbon documentation a while back in ReST, but it gave me an error. Docutils? See the problem is I already have some of it in ReStructedText.
