Title Body

I found out how to create a window in Cocoa programmatically but can't figure out how to react to events. The window is not reacting to a Quit request or button click. I tried adding the following controller and used setDelegate/setTarget without luck: @interface AppController : NSObject { } - (IBAction)doSomething:(id)sender; @end @implementation AppController - (IBAction)doSomething:(id)sender; { printf("Button clicked!\n"); } @end int main(int argc, char **args){ NSRect frame = NSMakeRect(0, 0, 200, 200); AppController *controller = [[AppController alloc] init]; > [[NSApplication sharedApplication] setDelegate:controller]; NSWindow* window = [[NSWindow alloc] initWithContentRect:frame styleMask:NSBorderlessWindowMask|NSClosableWindowMask|NSMiniaturizableWindowMask|NSResizableWindowMask backing:NSBackingStoreBuffered defer:NO]; [window setBackgroundColor:[NSColor blueColor]]; NSButton *button = [ [ NSButton alloc ] initWithFrame: NSMakeRect( 30.0, 20.0, 80.0, 50.0 ) ]; [ button setBezelStyle:NSRoundedBezelStyle]; [ button setTitle: @"Click" ]; > [ button setAction:@selector(doSomething:)]; > [ button setTarget:controller]; [ [ window contentView ] addSubview: button ]; [window makeKeyAndOrderFront:NSApp]; [[NSRunLoop currentRunLoop] run]; return 0; }
