Re: Windows and Default Notification Center

Thanks, I looked in the documentation of NSWindow for these functions but I
missed them.

I agree that the responder chain is the correct way to do this, but I am
having trouble making it work. At the end of my windowDidLoad function in
my NSWindowController I have the following command:

[[self window] makeFirstResponder:self];

And the window controller object contains the processCommandTest function.
In my dialog handler I pass the message to the first responder as follows:

NSApplication *thisApp = [NSApplication sharedApplication];
if ([thisApp respondsToSelector:(SEL)@"processCommandTest"]){

[thisApp tryToPerform:(SEL)@"processCommandTest" with:command];
}

But the respondsToSelector method always returns NO.
