i'm assuming this is simple, but i can't solve the problem. at launch
of the application, an NSRect is drawn with a userdefault color:

- (void)drawRect:(NSRect)rect
{
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSData *colorAsData;
colorAsData = [defaults objectForKey:@"aColor"];
NSColor *menuBarColor = [NSKeyedUnarchiver
unarchiveObjectWithData:colorAsData];
[menuBarColor set];
NSRectFill([self bounds]);
}

that works... but now i want that rect to redraw itself when notified
to do so, but i can't figure out how to notify the NSRect to draw
again... all my NSUserDefaults colorAsData is in place, as well as my
NSNotifications. it will print to NSLog so i know that notification
is being called, but how do direct that notification to the drawRect
method?

- (void)awakeFromNib
{
[MenuBarWindow setAlphaValue:0.0];
NSNotificationCenter *notificationCenter = [NSNotificationCenter
defaultCenter];
NSString *changeColorNotification = @"changeColorNotification";
[notificationCenter addObserver:self selector:@selector(changeColor:)
changeColorNotification object:nil];
}
- (void)changeColor:(NSNotification *)notification
{
NSLog(@"Call drawRect");
//call "drawRect:(NSRect)rect" method
Let me cover the obvious part....... ( just to see that no stone is
unturned )
you mean , even after when you tried [self setNeedsDisplay:YES] ????
I guess you know that , you are not supposed to invoke the drawRect
directly ......
Are you sure this what you wanted ? or I didn't get the tone of
obvious tricky question ??
