NSWindow configuration guide to keyboard events after focus change on macOS 13.6
I've looked through the documentation and I'm still confused about I've looked through the documentation and I'm still confused about I'm developing a macOS app using AppKit, and I've encountered a frustrating scenario where my `NSWindow` does not respond to keyboard events after I switch focus between different application windows....... This happens specifically when the window loses focus and regains it. I have implemented the `keyDown:` method to handle keyboard inputs, but it seems like the method is not being called when the window regains focus. Here’s the relevant code snippet: ```swift class MyWindow: NSWindow { override func keyDown(with event: NSEvent) { super.keyDown(with: event) print("Key pressed: \(event.keyCode)") } } ``` I’ve checked to ensure that the window is the key window using the `isKeyWindow` property, and I've confirmed that the responder chain is correctly set up. To troubleshoot, I tried calling `makeKeyAndOrderFront(nil)` on the window when it appears, but this does not seem to resolve the scenario. Additionally, I have tried overriding the `didBecomeKey()` method to add some logging, and it does log correctly when the window becomes key: ```swift override func didBecomeKey() { super.didBecomeKey() print("Window has become key") } ``` However, the `keyDown:` method still fails to capture any keyboard events after the window regains focus. I have checked the app's settings in System Preferences to ensure there are no accessibility options interfering with keyboard events. This scenario is occurring on macOS 13.6, and I am not sure whether it is a bug with the operating system or if I am missing something in my implementation. Has anyone experienced similar behavior or found a workaround for this? Any insights would be greatly appreciated! For context: I'm using Swift on macOS. Has anyone else encountered this? I'm working on a service that needs to handle this. Any help would be greatly appreciated! The stack includes Swift and several other technologies. I'd really appreciate any guidance on this.
