# dismissWindow

A window dismissal action stored in a view’s environment.

## Declaration

```swift
var dismissWindow: DismissWindowAction { get }
```

## Discussion

Discussion Use the dismissWindow environment value to get an DismissWindowAction instance for a given Environment. Then call the instance to dismiss a window. You call the instance directly because it defines a callAsFunction(id:) method that Swift calls when you call the instance. For example, you can define a button that dismisses an auxiliary window: @main struct MyApp: App {     var body: some Scene {         WindowGroup {             ContentView()         }         #if os(macOS)         Window("Auxiliary", id: "auxiliary") {             AuxiliaryContentView()         }         #endif     } }

struct DismissWindowButton: View {     @Environment(\.dismissWindow) private var dismissWindow

var body: some View {         Button("Close Auxiliary Window") {             dismissWindow(id: "auxiliary")         }     } } If the window was opened with pushWindow, the presenting window will reappear when this action is performed.
