# DismissBehavior

Programmatic window dismissal behaviors.

## Declaration

```swift
struct DismissBehavior
```

## Overview

Overview Use values of this type to control window dismissal during the current transaction. For example, to dismiss windows showing a modal presentation that would otherwise prohibit dismissal, use the destructive behavior: struct DismissWindowButton: View {     @Environment(\.dismissWindow) private var dismissWindow

var body: some View {         Button("Close Auxiliary Window") {             withTransaction(\.dismissBehavior, .destructive) {                 dismissWindow(id: "auxiliary")             }         }     } }
