macOS NSWindow HideOnDeactivate - event

[kwicher]

Hi

How do you detect that NSWindow lost focus and got hidden due to the HideOnDeactivate set to TRUE?

THanks

Do you know how to use delegate methods? Note that hideOnDeactivate means that the application itself is dropping back behind another one, so you could either use a window delegate method or notification or an app delegate or notification. Refer to the guides and documentation to learn how to handle this.

I know how to delegate etc but what message is sent to when the window disappears? It is not hidden because a simple test will show you that isVisible=TRUE.
Thanks

I'm not sure if it's what you are after, but the NSApplicationDelegate protocol has an applicationDidResignActive: method which is called when your app loses focus. There's also the [NSApplication isActive] method - if the app is inactive then you can infer that a window which is set to HideOnDeactivate is probably hidden.
