Re: GNUstep's GTK theme now changes when user selects a new theme...

[Eric Wasylishen]

Hi Greg,
I think I fixed the problem.. the GTK theme was forgetting to remove the 
existing slider/radio/switch images by calling -setName: nil, so the 
replacement images weren't being registered since [NSImage setName:] does 
nothing if the name is already in use.

In the longer term I'd like to come up with a more clearly defined API on 
NSImage for updating system images programatically. Currently GSTheme uses the 
+_setImagePath:name: method used when loading image files in theme bundles.

Maybe something like:

+[NSImage registerThemeImage: (NSImage *)anImageGeneratedByTheTheme
                         forName: (NSString *)aName];

This could use the same type of trick that +_setImagePath:name: does of reusing 
the existing registered NSImage instance, removing all of its reps, and copying 
in the reps from anImageGeneratedByTheTheme.
