I'm trying to write a dylib extension to the Tcl/Tk scripting language
that updates an application icon with a call to [NSApp
setApplicationIconImage]. My code works as expected until it is time for
me to restore the original application icon. At that point my app quits
with this error:
Terminating app due to uncaught exception
'NSInternalInconsistencyException', reason: 'Creating more than one
Application'
I have multiple calls to NSApp, which is apparently the problem--I am
not correctly setting the NSApp global. I've been advised to call
NSApplicationLoad(), since Tcl/Tk is currently based on Carbon, but I'm
not sure where to do this.
The relevant code is below. Any advice is appreciated. --Kevin

#import "cocoadock.h"
@implementation CocoaDock
// cocoa command to set the dock icon.
-(int) switchIcon: (NSString *) iconPath {
//set up autorelease pool
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
//convert file path to URL
iconURL = [[NSURL alloc] initFileURLWithPath: iconPath];
//create image from URL
newIcon = [[NSImage alloc] initWithContentsOfURL: iconURL];
//set the new icon
[NSApp setApplicationIconImage: newIcon];
//release the memory
[newIcon release];
[iconURL release];
[pool release];
return 0;
}
-(int) origIcon {
//set up autorelease pool
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
//restore the app icon
[NSApp setApplicationIconImage:nil];
[pool release];
return 0;
}
@end
