[Pyobjc-dev] Changing the dock icon

[David C. <da...@ne...>]

I am now trying to change the application's icon in the dock, depending on
different conditions.  I have found a URL that describes how to do this with
Objective C (http://cocoa.mamasam.com/COCOADEV/2002/12/1/51192.php), but I
am unsure of how to access the right NSApp to tell it to
setApplicationIconImage_ ... and then I assume I pass in an NSImage object
which I specified earlier.

FYI, I am now using the Python Template Project that comes with pyobjc, so
the current code that I'm working in is of class MyAppDelegate (subclassed
from AppKit.NibClassBuilder.AutoBaseClass).

Thanks,
David.

You can use either AppKit.NSApp(), a function instead of a global 
variable, or  NSApplication.sharedApplication() to access the 
NSApplication instance for your application.

OK, I've got AppKit.NSApp() going, but I need to feed an NSImage into

The line I'm using is --

closed_image = NSImage.initWithContentsOfFile_(
'/Users/david/Documents/gr-star.tif' )

-- which results in the following error --

2003-01-08 20:10:31.855 NewTunnels[851] First argument must be an
objective-C object, got '/Users/david/Documents/gr-star.tif'

-- the documentation for NSImage seems to suggest that I can put a path into
the function.  What is the correct way to create the NSImage so I can then
put that image into NSApp().setApplicationIconImage_ to change my dock icon?

Thanks,
David.

Try NSImage.alloc().initWithContentsOfFile_()...

-initWithContentsOfFile: is an instance method, not a class method.   
That error message is slightly obscure, but that is what it means.
