OK, while that's a very handy thing to know, I think I have worked out a
simpler way that does not require an intermediate class - I'll state it here
for the archives (and any comments welcome...)
I show the window using the following code:
@implementation Camera
-(void)showSettingsWindow
{
if (settingsWindowController == NULL)
[NSBundle loadNibNamed:@"Camera Settings" owner:self];
[settingsWindowController showWindow:self];
}
@end
... and the NIB file (File's Owner = Camera) contains the window and a
controller object (linked together), with the window controller linked to the
outlet "settingsWindowController" in File's Owner placeholder.
