# allowsWindowActivationEvents(_:) Configures whether gestures in this view hierarchy can handle events that activate the containing window. ``` nonisolated func allowsWindowActivationEvents(_ value: Bool?) -> some View ``` ## Parameters `value` A Boolean value that indicates whether gestures in this view hierarchy can handle events that activate the containing window. If `nil`, or if the modifier is not present, the behavior will be inherited from the view’s ancestors. ## Discussion Views higher in the hierarchy can override the value you set on this view. In the following example, the tap gesture on the `Rectangle` won’t handle events that activate the containing window because the outer `allowsWindowActivationEvents(_:)` view modifier overrides the inner one: ``` HStack { Rectangle() .onTapGesture { ... } .allowsWindowActivationEvents() } .allowsWindowActivationEvents(false) ``` > Note: It’s only possible to disallow handling events that activate the > containing window for views that allow it by default or that inherit > this behavior from their ancestors. Views that explicitly already > disallow this functionality can’t have it turned on. > Note: Prefer using ``doc://com.apple.SwiftUI/documentation/SwiftUI/View/allowsWindowActivationEvents()`` if the > parameter is always `true` and it never changes. --- Copyright © 2026 Apple Inc.
