Yes. As I answered before, you have to get things scheduled in the right
runloop mode. But once you do, it's quite easy:
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
NSStatusItem *item = [[[NSStatusBar systemStatusBar]
statusItemWithLength:24] retain];
[item setImage:[NSImage imageNamed:NSImageNameApplicationIcon]];
[item setEnabled:YES];
NSMenu *m = [[NSMenu alloc] init];
[item setMenu:m];
NSTimer *t = [NSTimer timerWithTimeInterval:1.0 target:self
selector:@selector(updateMenu:) userInfo:m repeats:YES];
[[NSRunLoop currentRunLoop] addTimer:t forMode:NSDefaultRunLoopMode];
[[NSRunLoop currentRunLoop] addTimer:t forMode:NSEventTrackingRunLoopMode];
}
- (void)updateMenu:(NSTimer *)t {
NSMenu *m = [t userInfo];
NSString *s = [[NSDate date] description];
NSMenuItem *i = [[NSMenuItem alloc] initWithTitle:s action:nil
keyEquivalent:@""];
[m addItem:i];
[m update];
}
Run that, open the poorly-iconed status item, and don't touch your mouse.
Yes, this code is terrible and leaks and all that. It's just to illustrate the
point.
