Re: [Pyobjc-dev] Calling python from objc

[Akhar <ak...@gm...>]

I seem to have been able to fix my problem by taking out (pyScript)
----Script.m,
#import "Script.h"

@implementation Script(pyScript) //<- offending line
+ instantiateSubclassNamed:(NSString*) aClassName
{
	Class aClass = NSClassFromString(aClassName);
	return [[aClass alloc] init];
}

@end
BUT i do get another error which is :
creating object
*** -[scr test]: selector not recognized
An uncaught exception was raised
*** -[scr test]: selector not recognized
*** Uncaught exception: <NSInvalidArgumentException> *** -[scr test]: 
selector not recognized

QuickShell has exited due to signal 5 (SIGTRAP).

[Pyobjc-dev] Calling python from objc

[Akhar <ak...@gm...>]

I seem to have a bit of a problem with calling python objects from 
cocoa apps. I did find your post on soureforge about how it could be 
done (http://sourceforge.net/mailarchive/message.php?msg_id=7503787).  
I tried to do as the poster did however I need to call the python code 
from another object that is linked to a custom view. Here is what I 
have :
-----main.m
#import <Cocoa/Cocoa.h>
#import <PythonGlue.h>
#import <Script.h>
int main(int argc, const char *argv[])
{
     return NSApplicationMain(argc, argv);
}

-----myoutput.h,
/* outputView */

#import <Cocoa/Cocoa.h>
#import <PythonGlue.h>
#import <Script.h>
@interface outputView : NSView
{
	NSString *command;
	NSColor *bgColor;
	NSMutableDictionary *attributes;
	Script *script;
}
- (void)prepareAttributes;
- (void)drawStringCenteredIn: (NSRect)bounds;
- (void)setBgColor:(NSColor *)c;
- (NSColor *)bgColor;
- (void)setString: (NSString *)cmd;
- (NSString *)command;
@end

----myoutput.m,
#import "outputView.h"

@implementation outputView

- (id)initWithFrame:(NSRect)rect
{
	if (self = [super initWithFrame:rect]) {
	[[PythonGlue alloc] init];
	scr = [Script instantiateSubclassNamed:@"pyScript"]; // this is where 
it should run the python code
	NSLog(@"initializing view the big one");
	[self prepareAttributes];
	[self setBgColor:[NSColor yellowColor]];
	[self setString:@"Nothing to see here! move on!"];
	}
	return self;
}
... more ... but ... cut ...
@end
----Script.h,
/* Shell */

#import <Cocoa/Cocoa.h>

@interface Script : NSObject
+ instatiateSubclassNamed: (NSString *) aClassName;
@end
@interface Script (pyScript)
- (void) test;
@end

----Script.m,
#import "Script.h"

@implementation Script(pyScript)
+ instantiateSubclassNamed:(NSString*) aClassName
{
	Class aClass = NSClassFromString(aClassName);
	return [[aClass alloc] init];
}

@end

----pyScript.py
from objc import *
from Foundation import *
from AppKit import *

Script = lookUpClass("Scipt")
class pyScript(Script):
     def init(self):
         print "creating object"
         return self
     def test_(self, obj):
		print "in python here test worked"

and the pythonglue.h/.m and the python framework.
 From that standpoint all seems great. I have the exact same setup as he 
does except for the main.m that was left as is. instead in myoutput.h I 
created the Script *py; variable to my knowledge this is not the 
problem, I get a:
  objc.nosuchclass_error: 'Script' is not defined. error.
What am i doing wrong?

Changing the signature is only necessary when the method will be called 
from Objective-C *and* PyObjC cannot know the signature (you never have 
to supply an explicit signature when overriding an existing method).

For this class it's totally worthless (as-is, at least), so I wouldn't 
have it in there..

This is taken straight from some example (I forget which)  - as a 
"pythonic constructor" so I can use this class in another python file 
more pythonically...

Mainly, I use it for unit testing... (if ever)

You don't.  You want class methods.

self is allowed to change after an init call!

         self = super(BaseView, self).initWithFrame_(frame)

Note that you did misspell paperSize ...

     def initWithPrintInfo_(self, info):
         frame = self.__class__.getFrameFromPaperSize_(info.paperSize())
         self = self.initWithFrame_(frame)
         return self

     # this should technically have a signature that returns NSRect and

[Pyobjc-dev] Inheritance questions....

[Jiva D. <ji...@de...>]

How do I call functions in a class which inherits from an objc class 
*before* i have finished initializing self?  My goal here is to call 
some subfunctions in my constructor before calling the inherited 
constructor.  But self is not yet initialized, so it doesn't work...

So, say I have the following code in a python file:

from Foundation import *
from AppKit import *

class BaseView(NSView):
     def __new__(cls, *args, **kwargs):
         return cls.alloc().init()

     def initWithFrame_(self, frame):
         super(BaseView, self).initWithFrame_(frame)
         return self

     def initWithPrintInfo_(self, info):
         self.info = info

         self.frame = self.getFrameFromPaperSize(info.papersize())

         self.initWithFrame_(frame)

         return self

     def getFrameFromPaperSize(self, size):
         return ((0, 0), (10, 10))

class Inherit1(BaseView):
     def getFrameFromPaperSize(self, size):

This cannot be solved in plain python, because the first argument is 
used to return an array of objects.

This is fixed in revision 1.6 of 
Modules/AppKit/_AppKitMapping_NSView.m, which should surface in a day 
or so. With that you can do::

    rects, count = myView.getRectsBeingDrawn_count()

[Pyobjc-dev] getRectsBeingDrawn:count: signature help

[Ted H. <ho...@ub...>]

I would like to use getRectsBeingDrawn:count: in a python NSView subclass,  
but I don't know how to declare the signature properly.  I tried:

setSignatureForSelector('NSView', 'getRectsBeingDrawn:count:',  
'v@:o^{_NSRect={_NSPoint=ff}{_NSSize=ff}}o^i')

and I get a rect back, but the data is bogus (not surprisingly).  If I use:

setSignatureForSelector('NSView', 'getRectsBeingDrawn:count:',  
'v@:o^^{_NSRect={_NSPoint=ff}{_NSSize=ff}}o^i')

I get something back (a PyObjCPointer), but I don't know how to access it.

What is the proper signature and usage of a method like this (ie one that  
returns a variable length list of struct through a pointer to a pointer).

Thanks,

Ted

It has nothing to do with sockets really, you probably just need to 
include the encodings package, the _codecs extension, and the codecs 
module.  These are all imported implicitly by Python internals 
as-needed, so BundleBuilder isn't necessarily going to pick it up on 
its own.

It's unlikely that the python installation from Panther will work on 
Jaguar. But anyway, you need to tell bundlebuilder that it must include 
the encodings package.

[Pyobjc-dev] PyObjC Standalone applications socket problem

[David G. <dg...@da...>]

Hello all,

I have been using PyObjC for a few weeks now and as a rule, I love it. 
I have hit a snag though. When I bundle an application using the 
--standalone option it builds, but the program fails when it goes to 
use a socket. This problem doesn't occur when I build with the 
--sem-standalone option, only when using the --standalone. The program 
actually continues to run, no crash or anything, but it does not do 
it's socket communications. The actual error that I find in the console 
is:

no codec search functions registered: can't find encoding

Any help with this would be appreciated. I am running on Panther with 
all the latest updates. The whole reason I need the --standalone option 
is because I have been getting requests for programs I have written 
from users on Jaguar, and the programs won't run on Jaguar as 
--semi-shared.

Thanks,

It's not a NSDictionary or a subclass of NSDictionary so PyObjC doesn't  
know that it needs the __getitem__ mapping.  It can't automatically say  
that all bridged objects should use valueForKey: for __getitem__  
because some should map to objectAtIndex:

You'll have to use the literal translation, at least for now:
prefs.valueForKey_(u'FontName')

Note that unicode strings are the literal translation of ObjC  
@"strings".  Regular Python strings can potentially hit an exception at  
the bridge and always incur additional encoding overhead... and  
besides, you should probably get in the habit of using unicode for all  
text anyway.

It is an NSCOP because it is not a static dictionary of values.  It is  
literally a proxy to the NSUserDefaultsController.

This raises a slightly different issue -- one that we have sort of  
punted on for a while.

Since KVC -- key/value coding -- is implemented on NSObject [both  
-valueForKey: and -setValue:forKey:] is there any reason to not support  
subscript style access to all Obj-C objects passed to the python side  
of the bridge?

It is a trivial change to make it so, I believe.

[Pyobjc-dev] NSUserDefaultsController

[Paul D. <pa...@do...>]

Hi,

I'm trying to use the new NSUserDefaultsController (part of Cocoa  
Bindings). I've got some example code in Obj-C (from  
http://homepage.mac.com/mmalc/CocoaExamples/controllers.html), but I'm  
having trouble converting it to PyObjC.

The original Obj-C code is:

	// Get font name and size from user defaults
	NSDictionary *values = [[NSUserDefaultsController  
sharedUserDefaultsController] values];
	NSString *fontName = [values valueForKey:@"FontName"];

So I've converted it to this:

		prefs =  
NSUserDefaultsController.sharedUserDefaultsController().values()
		print prefs
		print prefs['FontName']

Results in:

<_NSControllerObjectProxy: 0x1123830>
2004-04-13 00:12:22.453 Test[19056] An exception has occured:
Traceback (most recent call last):
   File

   File  
"/System/Library/Frameworks/Python.framework/Versions/2.3/lib/

RatingsModel.py", line 29, in makeLibrary
     print prefs['FontName']
TypeError: unsubscriptable object

I'm not sure why the type of 'prefs' is an NSControllerObjectProxy. I  
was expecting it to be an NSDictionary* (and hence a python  
dictionary). I have an instance of an NSUserDefaultsController in my  
nib file, so I'm a bit stuck at this point.

I'm using pyobjc from anonymous CVS as of a couple of days ago, on  
10.3.3.

Cheers,

Paul
