使用Cocoa和Objective-C++向NSWindow添加事件

#import <Cocoa/Cocoa.h>

@interface MyWindowDelegate : NSObject<NSWindowDelegate>

@end

@implementation MyWindowDelegate

- (void)windowDidBecomeKey:(NSNotification *)notification {
    NSLog(@"Window became key");
}

- (void)windowDidResignKey:(NSNotification *)notification {
    NSLog(@"Window resigned key");
}

@end

int main(int argc, const char * argv[]) {
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
    
    [NSApplication sharedApplication];
    
    NSWindow *window = [[NSWindow alloc] initWithContentRect:NSMakeRect(0, 0, 200, 200)
                                                   styleMask:NSWindowStyleMaskTitled
                                                     backing:NSBackingStoreBuffered
                                                       defer:NO];
    
    MyWindowDelegate *delegate = [[MyWindowDelegate alloc] init];
    [window setDelegate:delegate];
    
    [window makeKeyAndOrderFront:nil];
    
    [NSApp run];
    
    [pool drain];
    
    return 0;
}
