It is used in nearly every single example, though. I guess it should be reworded to be more obvious in the docs. -bob ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig

def init(self):
self = super(PySayTextAppDelegate, self).init()
return self
Also, READ THE DOCS and examples please, this is most definitely
covered a thousand times :)

Aldo --
PyObjC classes (that is, Python classes that extend ObjC ones, like
you're trying there) don't use the standard __init__ mechanism (at
least, not in a useful way). They do use the standard alloc/init
mechanism from ObjC, so you're on the right track in your last try:

The only think you're missing is a "return self" -- ObjC init methods
always return self, so you have to do the same from PyObjC.
Hope that helps,

[Pythonmac-SIG] Right init method
Dear list,
I have decided to try to practice pyObjC by translating (or trying to..)
the Objective-C examples of Aaron Hillegass' Cocoa Programming for MacOS
X, as I need to get up to date on Cocoa through Python.
I am trying to figure out how to translate the obj-C init method of the
SpeakLine example, chp 4.
The original obj-C is:
- (id)init
{
[super init]
NSLog(@"init");
speechSynth = [[NSSpeechSynthetizer alloc] initWithVoice:nil];
return self;
}
This is the init method of an application controller class, created
inside InterfaceBuilder..
I tried to translate it as:
class PySayTextAppDelegate(NibClassBuilder.AutoBaseClass):
#IB defined outlets
#textField
#speechSynthetizer
#
#IB defined actions
#sayIt_
#stopIt_
def __init__(self):
super.__init__(self)
NSLog("init")
self.speechSynth = NSSpeechSynthetizer.alloc().initWithVoice_(nil)
This is a regular Python init method; I do not see the ''init" string in
the Console app . And therefore the synthetizer object is not created.
The same happens for this 'version':
def init_(self):
super.init_(self)
NSLog("init")
self.speechSynth = NSSpeechSynthetizer.alloc().initWithVoice_(nil)
The last one does 'build' but does not start:
def init(self):
super.init(self)
NSLog("init")
self.speechSynth = NSSpeechSynthetizer.alloc().initWithVoice_(nil)
Where can I findout how to initialize objects?
Thanks
Aldo
