Stopping modal when window is closed (Cocoa)

Question

I am currently displaying a modal window by using this code:

[[NSApplication sharedApplication] runModalForWindow:mainWindow];

However, when I close this window, the other windows are still inactive. How do I run the stopModal method when the window is closed using the "red x"?

Thank you,

Michael

You can create a delegate for the window and have it respond to either the
-(void)windowWillClose:(NSNotification *)notification or the
- (void)windowShouldClose:(NSNotification *)notification methods like so:

- (void)windowWillClose:(NSNotification *)notification {
   [[NSApplication sharedApplication] stopModal];
}
