This should all work, if your original program was a pure unix program. The WaitNextEvent comments you can safely ignore unless your program has a Mac GUI (using WaitNextEvent) in which case you may have to be aware of the interaction between WaitNextEvent and select(). Could you elaborate on what you mean by "things go blank (literally)"? What is happening, and what had you expected to happen? -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen(a)oratrix.com | ++++ if you agree copy these lines to your sig ++++ www.oratrix.nl/~jack | see http://www.xs4all.nl/~tank/spg-l/sigaction.htm

Well, this probably isn't much of a priority at this point, but I had two problems. [1] I loaded v. 2.0c1 on a Mac OS X machine and the IDE launched fine under Classic, except the very first time there was a huge version of the icon that was on top of everything except the menubar (it was even on top of title bars for items that were dragged "under" it after the fact. When I quit the IDE the huge icon *faded* away -- very weird. I tried to duplicate this but wasn't successful. This was cosmetic and it went away so I don't think it is a big problem. [2] I tried installing the Sherlock sites (or whatever one is supposed to call those files) and I was able to make them appear as a channel in the Mac OS X Sherlock, but when I searched using them they did not work. "Python FAQ" always says there is a network error (the only site to give such error and it always gives it), and the other two always return no items. I even searched for "python" figuring that would hit on *something* but it didn't. (Again, to be clear, I tried the other channels, like alta vista, and that worked fine, then switched back and got nothing). Probably not a high priority, but I thought I would let people know.

Porting assistance.
by Suresh L Konda Oct. 12, 2000

Oct. 12, 2000

Hi all, I am porting a "pure" python app (a server actually) from unix to the Mac and find myself considerably lost. Specifically, the original app relied completely on a select() based eventloop to deal with all io including console io, socket io, file io, pipe io etc. When I ported to the NT, I was forced to create a tcp-based "console" since stdin etc. are not selectable on that platform but the rest worked fine. With the Mac, I seem to be in trouble with conflicting eventloops -- at least my select based eventloop and some other eventloop(s?). From what I can figure out (after doing the dumb thing of a "straight" port of the unix version including the select() based console), select() does get the io read-ready on stdin and appropritely writes to stdout. However, after that, things go blank (literally) on me leading me to believe that there is some other eventhandler that I should be calling (or registering my select() based eventloop with it). There were some tantalizing comments in the SIG archives regarding interleaving WaitNextEvent() and select() but, I am afraid, I remain lost. A couple of other issues that I need to deal with: currently the server uses os.system(), os.popen(), and the like to get other applications to do work for it. Are there any equivalents or workarounds on the Mac for these? Also, how does one pass arguments to another application? Any and all assistance would be most appreciated. Thanks in advance. Suresh

Gadfly and mac
by tom smith Oct. 12, 2000

Oct. 12, 2000

hi, I've got the gadfly database going on my mac, but I needed to use the EditPythonPrefs utility and run some of the scripts in the python folder. There is a slight problem, along the lines of, I have to open and run Gadfly.py before import gadfly will import without erroring. It says.. call of non function (type module) ..yet gadfly appears in the modules window. any ideas? tom p.s I'm using python 2

I set up a wiki at http://tony.lownds.com/macosx/wiki/ - the only thing left to do is actually post a todo list. I'll do that soon, in the meantime, feel free to sign on and do the wiki thing to it. -Tony Lownds

Qd questions
by Nick Collier Oct. 11, 2000

Oct. 11, 2000

Hi, I'm trying to use Qd to draw in a window of my own creation, but I'm think I'm missing something basic here. I start an interactive interpreter under the Python IDE and do the following: w = Window((300, 300), "hello") w.open() So far so good, a window appears. I then do: Qd.SetPort(w.wid) Qd.MoveTo(10, 10) Qd.LineTo(150, 150) And the line appears in the interpreter window not in the "hello" window. I've also tried doing Qd.SetPort(w.wid.GetWindowPort()) w.SetPort() and then the line draw, but the result is the same. It looks like Qd is not drawing to the correct GrafPort. I also ran the above code as a script as the result was the same. So, how do I this? On a related note, how can I use Win.NewCWindow to create a visible window on the screen? Do I need to wrap it somehow? Details are very much appreciated. thanks, Nick -- Nick Collier Social Science Research Computing University of Chicago http://repast.sourceforge.net

QuickDraw

Oct. 11, 2000

Hi, Are there any tutorial, examples, etc. of working with QuickDraw and W out there. Specifically, I'd like to be able to set up a full screen window (i.e. no title bar, no menu, no frame, etc.) and then draw some lines in it. thanks, Nick -- Nick Collier Social Science Research Computing University of Chicago http://repast.sourceforge.net

It may be there for CW Pro 6, but I wouldn't count on it. If you can point me to a publicly available and distributable strptime C routine I'll gladly incorporate it in MacPython. -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen(a)oratrix.com | ++++ if you agree copy these lines to your sig ++++ www.oratrix.nl/~jack | see http://www.xs4all.nl/~tank/spg-l/sigaction.htm

Oh, gosh, that reminds me! Tony, I tried your patches to get 2.0b2 to compile, and I ran into a few problems. My set of compiler tools didn't recognize "-undefined ignore". It wanted "-undefined suppress" instead. After that switch, it worked fine. Has anyone else run into this? I guess I should try 2.0c1 now. Also, I had to resort to a bit of hackery to get Numeric-17.0 to compile, but now I'm uncertain whether it's just my set of compilation tools, which I "borrowed" from the Darwin 1.0.2 distribution. --J
