EasyDialog? ID Values?
by Schollnick, Benjamin Nov. 28, 2001

Nov. 28, 2001

Folks, I have noticed that in EasyDialogs, there are ID numbers, that appear to be associated with each dialog style? Is there any place, I can lookup these ID's? To see if there is a different dialog window style, I'd like to implement? - Benjamin

Re: [Pythonmac-SIG] Python-friendly Databases for the Mac

Hi- If you need SQL-ish capability, this won't help you. But if you just need a handy and very Pythonic way to store and retrieve objects, I've compiled the Zope Object Database (ZODB) for the Mac. I will put it online soon, but I'm swamped this week (and out of town most of it), so it won't happen for at least a week. If you need it more quickly, drop me an email and I'll try to email you a Stuffit file. It is for MacPython 2.1.1 on the PPC. -Tom Loredo

First, note the 3 line count was an embarrassing typo I noticed when I got the message back from the list. It's about 30 lines. In another message to the list, I have posted the code, though. h >Hello, > >"Marcus H.

Last time I >looked at it at sourceforge.net I didn't find any working package or only a >clone of an elder Piddle package afair. The reason I haven't said more about sping is that I am still using Piddle. I couldn't get Sping to work without a bunch of messing around and, as I mentioned, the last time I tried the QD backed didn't exist. Since Piddle works awfully well (after one figures out how to use it and its sidekick, graphite, a scientific graphing package). Marcus

sample Piddle code

From what I can tell printing is still one of >the weaknesses of Python. the Piddle module is your friend for printing. It is in the process of being superseded by Sping, but I don't think the quickdraw backend is in Sping, and it works great in Piddle. Piddle is a platform-independent (reasonably) graphics interface for Python. The most important part of it is that it generates pdf's beautifully, which gives a nice interface for printing documents. I use it for label printing, etc. routinely. I have a (very crude) label printing package built on Piddle (it's only about 30 lines of code) which, if you are interested, I can send along as an example of using Piddle. In this round of the message, I have attached a sample label-printing utility. I gzipped it to prevent line-break problems that mailers tend to create. It should be moderately self-explanatory, but I can give help as needed. Marcus Mendenhall >Any help would be appreciated. > >Thanks, >Gordon R. Vaughan

You should try and get to read this error message, or try to get a stack trace from your program and/or the IDE. What you could try doing is running the IDE from source, with a couple of runtime options turned on that may allow you to see the output. Option-drag PythonIDE.py (it's in :Mac:Tools:IDE) to the PythonInterpreter, and in the initial options dialog set at least "interactive after script" and "keep console open always". There's a chance that this is good enough to make the flashing dialog stay. If it doesn't there's a good chance that after the IDE crashes you'll get a normal interpreter prompt in the normal interpreter window. Type "import pdb ; pdb.pm()" and you can start doing post-mortem debugging. -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen(a)oratrix.com | ++++ if you agree copy these lines to your sig ++++ www.cwi.nl/~jack | see http://www.xs4all.nl/~tank/spg-l/sigaction.htm

Problem with W and shelve (Python 2.11)
by Josh English Nov. 26, 2001

Nov. 26, 2001

Hello all, After my Mac crashed I had to reinstall Python 2.1.1 from scratch, and now my old files aren't working properly. I had a database of my books in a shelve file, and I had created a program using W to give me a GUI editor for the database. It worked fine before the crash, now the IDE just quits as soon as I run the file. I started over and this file shuts the IDE down as soon as I hit run: import W import shelve def endprogram(): db.close() root.close() db = shelve.open('mybooks') l = len(db) root = W.Window((500,340), "Booklist", minsize = (240,180)) root.closebtn = W.Button((-74,-54,58,20),"Save&Quit",endprogram) root.open() It seems that any code that accesses the database file causes this problem. I can access the 'mybooks' file in the interpreter without any difficulty. Does anyone have any suggestions to trouble shoot this one. I think an error message pops up in it's own window, but it is just a flash before it all disappears. Josh English english(a)spiritone.com

Python-friendly Databases for the Mac
by Gordon R. Vaughan Nov. 26, 2001

Nov. 26, 2001

I'm still pretty new to Python but looking to do some basic database work on the Mac. I'm aware of PostgreSQL and MySQL for example but not sure how well they actually work with Python at present. Are these good choices for Mac OS 9? Also, I'm concerned about practical stuff such as reporting and label printing. Are there Python modules for these tasks that work well, or other means for accomplishing this? From what I can tell printing is still one of the weaknesses of Python. Any help would be appreciated. Thanks, Gordon R. Vaughan

MacPython 2.2b2 available
by Jack Jansen Nov. 25, 2001

Nov. 25, 2001

Folks, MacPython 2.2b2 is available. For your eyes only for the next 24 hours, and then I'll announce it to the rest of the world. Download it from http://www.cwi.nl/ftp/jack/python/mac . I'd really like people to beta test this release, as there are two changes to the lowlevel infrastructure that may have more consequences than intended (i.e. bad ones:-): there's a new GUSI library used for I/O and the handling of events and command-. has been changed significantly to fix some really old bugs. Please let me know about problems ASAP, -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen(a)oratrix.com | ++++ if you agree copy these lines to your sig ++++ www.cwi.nl/~jack | ++++ see http://www.xs4all.nl/~tank/ ++++

Macintosh Distribution of PIL ?
by Sean Hummel Nov. 24, 2001

Nov. 24, 2001

I know there used to be a distribution of the Python Imaging Library for the Macintosh version of Python. However I don't seem to be able to find a distribution for it any longer. Anyone still have a working distribution somewhere out there?
