pub unsafe static NSApplicationDidChangeOcclusionStateNotification: &'static NSNotificationNameAvailable on crate feature
NSApplication only.Expand description
Upon receiving this notification, you can query the NSApplication for its occlusion state. Note that this only notifies about changes in the state of the occlusion, not when the occlusion region changes. You can use this notification to increase responsiveness and save power, by halting any expensive calculations that the user can not see.
