One way to do this is giving the first class a number of outlets that can be connected to NSTextFields or MyViews. If you then implement 'setFloatValue_' in MyView you can connect your outlets to MyView to show the results. BTW. This is a very basic Cocoa question. May I suggest looking for a Cocoa tutorial?

[Pythonmac-SIG] simple pyobjc question
I have 2 classes, one which responds to user input, calculates stuff and displays the result in a series of NSTextFields, and a second class that is a subclass of NSView called MyView, which can display the same type of information graphically. What I'd like is for the first class to be able to use MyView to display its results, but I don't know how to get them to talk to each other. If I had an instance of MyView I could pass in data and call setNeedsDisplay(True) via a button in the interface. How should I do this?

I really noticed that the APIdocumentation that apple provides is extremely hard to navigate. Mybuddy told me that there are programs to read the documentation. Of all the programing languages and all the API's I have learned, this is thefirst time I've heard of such a thing. I'm not sure what exactly thissays about the API, but I'm thinking its not good. I don't really have a point to make here. And with that...I think it's a very good point. It would be really nice if Apple had all the documentation in the header files, so that documentation in different formats (like Apple's current docs, or like Java html docs, or whatever) could be autogenerated, in particular so that people could generate whatever kind of docs they wanted. If that were the case, it should even be easy to even generate PyObjC-syntax docs for the frameworks.

However, the API documentation is all installed along with XCode, ready for there to use. You can browse the docs within XCode, but instead I'd recommend AppKiDo:
http://homepage.mac.com/aglee/downloads/appkido.htmlIt looks through the installed API documentation, and provides a slick, quick interface to search browse the class libraries, more quickly and effectively than a print book could ever provide (IMHO).

Two things: 1. appscript only works for applications that have an aete/sdef
terminology resource, and 2. it doesn't support the special 'ascrbsbr' event,
which is not something used outside of AppleScript applets. You'd need to use
aem instead:
from aem import *
Application(a).event('ascrpsbr', {'snam':'processevent', '':['system',
'start']}).send()
Anyway, the usual approach would be to define a standard AE handler, e.g.
'PCAVProE', with named parameters, '' (direct) and 'Par2'. That allows you
to write:
Application(a).event('PCAVProE', {'':'system', 'Par2':'start'}).send()
or:
tell application a
set r to «event PCAVProE» "system" given «class Par2»:"start"
end tell
You can then add an aete/sdef resource to provide terminology for that command
if you want.
