PyObjC has limited support for GNUstep on Linux/ix86.

My primary linux box is headless, which is why I didn't get around=20
porting the GUI parts (of PyObjC) yet. I also have no idea if GNUstep=20
supports the API's used by the pdf2tiff script.

There's your problem... No, this application is not valid for Windows.=20=

PyObjC is a binding to the Cocoa libraries on MacOS X.

thanks for the line to setup:)

look at what I do:
"	c:\python setup.py install
	running install
	running build
	running build_py
	running install_lib

	c:\python pdf2tiff.py
	PyObjC not found - get it from http://pyobc.sf.net

did I make another mistake?

did this aplication is valid for windows?

I know this is an old post, my apologies... just wanted a

factory method without having the real class?

Any pointers to some example code for this?

You forgot the last step: run 'python setup.py install' from the shell=20=

[Pyobjc-dev] problem with launching pdf2tiff demo script

[PIGEYRE B. <bas...@in...>]

hello all,

I'have unzip the unzip file fro the web site, then when I right click on =
the pdf2tiff.py I choose open with idle. then I try to lauch it like =
this:

>>> import pdf2tiff
PyObjC not found - get it from http://pyobjc.sf.net
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in ?
    import pdf2tiff
  File "C:\bastien\pdf2st33\pdf2tiff.py", line 56, in ?
    showUsage("PyObjC not found - get it from http://pyobjc.sf.net")
  File "C:\bastien\pdf2st33\pdf2tiff.py", line 50, in showUsage
    sys.exit(1)
SystemExit: 1

but it doesn't find the pyobjc so i download the pyobjc1.0.tar and untar =
in my working directory but I have always the same error.

did someone as an idea?

thanks a lot and have a happy new year:)

Multiple NIBs with PyObjC really isn't any different than multiple NIBs 
with ObjC.   You just need to make sure that the classes used in the 
NIB file are loaded (import ClassName) before you load a NIB file that 
uses them.   The main.py/__main__.py does exactly this with the app 
delegate.

The project builder templates will work with Xcode just fine.  If your 
applications are targeted to 10.3 and framework python on 10.2, then 
you will want to modify the project builder template to use the 
embedded interpreter based main.   The resulting app will launch faster 
and be a lot easier to debug with gdb, if necessary.  It also allows 
you to freely intermix Objective-C and python in a single project 
without the embedded framework goofiness of the Python-ObjC-Cocoa 
project template.

There is a single working Xcode template in the repository;  the Xocde 
Cocoa Application (not Document Based).   The main .m file in that 
template can be used directly.

(I really need to upgrade that template...)

WebServicesTool in the Examples directory is a document-based 
application that uses multiple NIBs.

It uses a Project-builder project and Xcode should be able to use that.

[Pyobjc-dev] multiple-nib example?

[Steven D.A. <st...@ne...>]

Hi,

Is there an example of a full XCode-based PyObjC project that uses 
multiple NIBs?  I looked through the examples but didn't see anything.  
Are there any open-source projects that utilize PyObjC that I might 
look at?

Thanks in advance for any pointers,

It seems I forgot to update the status of the 1.0 release, it should be

I thought I'd start the new year by updating my PyObjC installation.
In the process I noticed a couple of small problems on the PyObjC
website.  (Apologies if y'all are already aware of these.)

Here's the short form:
One of the main hyperlinks to the PyObjC 1.0 distribution seems to point
to the wrong place.  And it would be great if references to 
PackageManager
were hyperlinks to the MacPython addons installer.

Here's the long form.

I've implemented this, but have not yet checked it in because I do not 
yet have a unittest that
will crash the current version of PyObjC. I'd like to have a unittest 
that triggers this behaviour without using a GUI or NIB files.

As a side-effect of this change I also fixed some bugs in code that I 
don't think will ever be used (anyone writing subclasses of NSData in 
python?).

[Pyobjc-dev] Dubious unittest

[Ronald O. <ous...@ci...>]

Background: objc.classAddMethods can be used to add new methods to an 
Objective-C class (like categories in Objective-C). One of the 
unittests does something like this:

# Start of code
class NewMethods:
	def method1(self):
		pass

objc.classAddMethods(NSObject, [ NewMethods.method1 ])
# End of code


This unittests fails because of an exception when trying to use 
NSObject.method1. This raises and exception because NSObject.method1 is 
actually an method of NewMethods and self is therefore of the wrong 
type. The same effect can be observed like this:

# Start of code
class C1:
	def printme(self): print "me"

class C2: pass

C2.printme = C1.printme

c = C2()
c.printme()
# End of code

It would be possible to change the code so that the unittest would 
pass, but given the behaviour of normal class I'd prefer to declare the 
current behaviour correct.

It's not necessarily 'evil', just exploiting the dynamic nature of the 
ObjC runtime. PyObjC incorrectly assumes that nobody will play such 
games, and that is a, fixable, bug.

Not really. The ObjC method dispatch table currently contains a 
method-stub that dispatches again to find the Python callable that 
actually implements the method, basically:

	id imp_foo(id self, SEL _meth, ...)
	{
		PyObject* selfObj;
		PyObject* methObj;

		selfObj = PyObjC_IdToPython(self);
		methObj = PyObject_GetAttrString(selfObj, (char*)_meth);

		// Gather the arguments in a tuple and call 'methObj'
	}

By using libffi even more than we do now we can basically pass the 
'methObj' as an extra argument to 'imp_foo'. That way we loose one 
level of dynamic dispatch, which could be slightly faster.

If this is implemented correctly the user of PyObjC won't notice a 
thing (other than KVO not crashing anymore). I've done a quick test and 
this actually works, I'm going to work on the correct implementation of 
this.

This might not even work with the current implementation, if Python 
methods get replaced in C code the Python side won't pick up the 
changes. I'll look into this as well :-)

See above.

The interesting question: should the __setattr__ of Objective-C objects 
implement KVO? E.g. should 'self.foo = bar' notify observers or should 
we rely on accessors. I'd say that the assignment should notify 
observers, especially because accessors are not necessary to be able to 
use KeyValueCoding.

That is exactly what is happening.   As others have discovered, 
automatic KVO works leveraging posing type behavior to override the 
setters and getters such that change notification can be automated.

Somewhat evil, yes, but it is efficient and transparent in the case 
where you aren't playing intense games with the runtime (as does 
PyObjC).

This would defeat the dynamic dispatch inherit to both objc and python, 
correct?   I.e. if I write...

x.doSomething()
y.editTheRuntime()
x.doSomething()

... and editTheRuntime() does exactly that, then the second invocation 
could lead to a completely different implementation of doSomething().

KVO is somewhat misnamed -- it isn't limited to key/value coding.    
That is the whole point behind doing some relatively low level edits to 
the runtime to make KVO work the way it does.   By doing so, it breaks 
the dependency on the developer always changing the value through the 
NSKeyValueCoding methods, thus making change observation transparent to 
the usage of the class (as long as the developer uses the setters and 
getters, directly or indirectly, the changes will be observed).

Could the existing functionality be modified such that the presence of 
the notifying posed class does not break the dispatch into Python?

Re: [Pyobjc-dev] Problem with PyObjC-HEAD on Jaguar?

[Ronald O. <ous...@ci...>]

Could you try removing PyObjC from site-packages and reinstalling it, 
I'm pretty sure some of the extension modules were moved after the 1.0 
release and you seem to be getting an old version of one of those 
modules.

[Pyobjc-dev] Problem with PyObjC-HEAD on Jaguar?

Any thoughts?

Re: [Pyobjc-dev] Controller Layer

[Ronald O. <ous...@ci...>]

I finally found some time to look into this, and this seems to be 
caused by an implementation trick in Cocoa.

For some reason the instance of 'Converter' is an instance of 
'NSNotifying_Converter' during the call to 'getAmount', and 'getAmount' 
is not recognized as a Python method which is causing infinite 
recursion. The class of the object is probably changed to implement 
some feature of KVO.

This is fixable by using libffi more agressively, although this may 
have other negative effects. E.g., we should use libffi to find the 
exact Python function to the method stub, instead of looking up the 
Python method in the class when it is called.

rum for addressing commercial developments in high-brightness LEDs, as wel=
l as an unparalleled networking opportunity for suppliers and users of the=
se devices. The growing interest in, and expanding attendance at, this eve=
nt, reflects the excitement associated with a market that has grown by 50=
% since 2000, while other semiconductor and optical component industries h=
ave stagnated or experienced large declines.



ON-SCREEN=99 TECHNOLOGY

OnScreen=99 is expected to create a broad-range of products with much bett=
er resolution and brighter pictures than the current generation of display=
s. OnScreen=99 will be visible in direct sunlight yet avoid many of the is=
sues associated with current displays including sun-loading, wind-loading =
and excessive weight.  In addition, the new LED architecture produces an a=
dvantage that is not available in today's marketplace: a more lightweight,=
 pliable display that can fit any application.  These are important advant=
ages as the High Brightness LED market is expected to grow from 1.2 billio=
n dollars in 2000 to 4 billion in 2006.  In addition, according to Stanfor=
d Resources, the LED sign market value alone is expected to exceed 1 billi=
on by 2006. These projections are made based on existing technology and do=
 not take into account emerging technologies, such as OnScreen=99, that ca=
n rapidly alter the size and shape of this market.



COMMERCIAL MARKET & STRATEGY

NMMG's initial marketing strategy revolves around licensing intellectual p=
roperty (IP) to worldwide manufacturers of LED display products and compon=
ents. The LED sign market is projected to reach over 1 billion dollars by =
2006. Lumiled's projects that high brightness LED's, used in LED signs alo=
ne, will exceed 1.2 billion by 2007. If these projections hold, the fully =
manufactured signs would represent a $5 billion market. Whichever number i=
s accurate, they both point towards a robust market for these new LED disp=
lays. Many projections don't take into account emerging high growth applic=
ations such as the Amber Alert project, Homeland Security and roadway =93i=
ntelligent message transfer=94.



THE MARKET

An article in Media Post's Media Daily News in March of 2003 noted that th=
e outdoor industry has successfully weathered the recession and that =93ou=
r large members say they're having a great first quarter=94 in 2003. They =
go on to note that technology is expected to transform both the display an=
d measurement of outdoor advertising. According to Media Daily the most ex=
citing news is coming on the display side, where =93Lamar Advertising is c=
onverting their key boards to LED units whose messages can be changed at w=
ill and sold in day-parts by the hour or even the minute.=94 They added th=
at =93Clear Channel's backlit subway panels in stairwells are being conver=
ted to LED as well=94. Together these companies represent two of the three=
 largest outdoor US advertisers.  

Recent Federal Government legislation has also placed a spotlight on expan=
ding the =93Amber Alert=94 network nationwide. The highly publicized succe=
ss in locating a number of kidnapped children shortly after their abductio=
n in California has now triggered federal funding for U.S.-wide expansion =
of these variable-message signs.  Homeland Security issues have also incre=
ased the number of early warning signs being planned and funded as part of=
 an overall information sharing network. Traffic safety is also becoming a=
 much higher priority in the U.S.. It is estimated that just over 60,000 r=
oadway dynamic message signs are in operation in the United States. In Jap=
an alone there are over 1.5 million of these signs. The United States repr=
esents a huge growth market for LED displays.



GROWTH OPPORTUNITES

In addition to the outdoor television market, another interesting and exci=
ting application for OnScreen=99 arrays is artistic lighting in dramatic c=
urved and shaped displays in places like Las Vegas, New York City or reall=
y virtually any venue. The tensile, flexible structure of OnScreen=99 prov=
ides unlimited opportunity for creativity. 

The anticipated cost reductions of OnScreen=99 will also provide ample opp=
ortunity for growth of the large-scale LED display market itself. OnScreen=
=99's unique architecture opens the door for new applications such as curv=
ed implementations, billboards on the sides of buildings where tenants can=
 still see out, and lower cost mobile applications on the sides of existin=
g vehicles. 

Homeland Security, Amber Alert variable message signage and instant messag=
e transfer applications can also benefit significantly from the advantages=
 of OnScreen=99. Reduced wind-loading and weight can significantly lower t=
he cost of the superstructures required to support these signs and also re=
duce the cost to install and maintain them.

Re: [Pyobjc-dev] Comparing int and floats fails?

[Francesco P. <fpi...@no...>]

Ummm...

For some reason, Python doesn't read my mind: it keeps reading my code, 
instead! :-)

I was comparing strings and floats, of course...
